Neurectomy

A neurectomy is a neurosurgical procedure involving the surgical transection or partial resection of a peripheral nerve, typically targeting small sensory nerves to interrupt pain signals and induce localized numbness for the management of intractable chronic pain.^[1] This intervention is generally considered a last-resort option after failure of conservative therapies, such as medications or less invasive neurolytic blocks, due to its potential for permanent nerve damage.^[1] Commonly performed under local or general anesthesia, the procedure entails precise identification and severing of the affected nerve, often guided by prior diagnostic nerve blocks or imaging to ensure accuracy and limit collateral effects.^[1] Neurectomies are categorized by anatomical location and nerve type, with peripheral neurectomy being the most frequent, involving postganglionic branches of nerves like the trigeminal for facial pain or ilioinguinal for groin discomfort.^[2]^[3] Other variants include dorsal rhizotomy, which targets spinal nerve roots, and specialized approaches like vestibular neurectomy for balance disorders. Key indications include refractory trigeminal neuralgia, where peripheral avulsion of terminal branches provides relief lasting 15–24 months or longer with preventive measures against regeneration; chronic pelvic pain syndromes; and neuropathic pain following procedures such as hernia repair, with studies showing significant pain reduction in many cases across various neurectomy techniques.^[1]^[2] It is particularly suitable for elderly patients or those in remote areas lacking advanced neurosurgical facilities.^[2] Neurectomy is also employed in veterinary medicine, particularly for managing chronic lameness in horses.^[4] Despite its efficacy, neurectomy carries risks including deafferentation pain (hypersensitivity in denervated areas), formation of painful neuromas from nerve regrowth, permanent sensory deficits, and rare motor impairments if mixed nerves are involved; complication rates are low in reported series but underscore the need for careful patient selection.^[1]

Definition and Overview

Definition

A neurectomy is a neurosurgical procedure involving the surgical excision, transection, or resection of part or all of a peripheral nerve.^[5]^[6] The term derives from the Greek "neuron," meaning nerve, combined with "-ektomia," a New Latin form of the Greek "ektomē," denoting a cutting out, from "ek" (out) and "temnein" (to cut).^[7] This etymology reflects the procedure's core action of excising neural tissue to achieve therapeutic outcomes. The basic mechanism of neurectomy entails the permanent interruption of nerve conduction, thereby eliminating the transmission of pain signals or aberrant neural activity along the targeted nerve pathway.^[6]^[8] Unlike temporary interventions such as nerve blocks, which use pharmacological agents to transiently block nerve function for diagnostic or short-term analgesic purposes, neurectomy produces a lasting disruption, often reserved for refractory cases where less invasive options fail.^[9] This permanence distinguishes it as a more definitive, albeit irreversible, approach to managing chronic neuropathic conditions. Neurectomy is strictly limited to peripheral nerves, excluding interventions in the central nervous system due to the higher risks and complexities involved. It encompasses a range of techniques, from complete surgical resection of the nerve segment to partial ablation methods, tailored to the nerve's size, location, and sensory versus motor function.^[8]^[6]

Classification of Procedures

Neurectomy procedures are classified based on anatomical location, surgical techniques, and therapeutic purposes to guide clinical decision-making and optimize outcomes. Anatomically, neurectomies target peripheral nerves, classified by their location, such as intracranial peripheral nerves within the cranium or spinal canal (e.g., the vestibular nerve for vertigo management), or extracranial peripheral nerves outside these areas (e.g., the intercostal or lateral femoral cutaneous nerves for localized pain syndromes).^[10]^[11] Furthermore, classifications distinguish autonomic neurectomies, which interrupt sympathetic or parasympathetic pathways (e.g., presacral neurectomy for pelvic visceral control), from those targeting sensory or motor nerves, such as sensory branches in trigeminal neuralgia or motor branches in spastic muscle denervation.^[12]^[13] Technique-based classifications emphasize the method of nerve interruption, including traditional surgical resection via open or laparoscopic approaches, which physically excise or transect the nerve for definitive denervation, as seen in open triple neurectomy for post-herniorrhaphy pain achieving up to 98% improvement rates.^[14] Minimally invasive methods, including endoscopic or robotic-assisted procedures, reduce tissue trauma; for instance, endoscopic thoracic sympathectomy employs small incisions for precise nerve clipping in hyperhidrosis treatment.^[15]^[16] Purpose-based categorizations align procedures with clinical goals, primarily pain relief for neuropathic or chronic conditions, where peripheral neurectomy of trigeminal branches provides short- to medium-term relief in refractory cases.^[13] Functional disablement targets symptom control, such as vestibular neurectomy to eliminate aberrant vestibular signals causing vertigo while preserving hearing in unilateral peripheral disorders.^[10] Autonomic modulation addresses dysregulations like hyperhidrosis through sympathectomy, which interrupts sympathetic chains to halt excessive glandular activity, with endoscopic variants yielding high success rates in primary cases.^[17]^[18] These classifications overlap in practice, allowing tailored selection based on patient anatomy and pathology.

History

Early Surgical Developments

The 19th century marked the introduction of neurectomy as a deliberate surgical intervention, primarily for trigeminal neuralgia, a debilitating facial pain condition. Peripheral neurectomies, involving the cutting of trigeminal nerve branches, were first attempted around 1830, with initial successes reported in alleviating tic douloureux symptoms through resection of supraorbital or infraorbital nerves. Systematic documentation and reviews of these procedures proliferated between 1869 and 1895, as surgeons refined techniques to target peripheral branches while minimizing complications like anesthesia dolorosa. By the late 1800s, more invasive approaches emerged, such as the 1856 trans-antral exposure of the trigeminal ganglion by John Murray Carnochan and the 1891 intradural sectioning of preganglionic rootlets by Victor Horsley, establishing neurectomy as a viable option for intractable neuralgia when medical therapies failed. Early 20th-century milestones expanded neurectomy's applications beyond the face, with pioneering work in pelvic and vestibular domains. Presacral neurectomy, targeting sympathetic nerves for severe dysmenorrhea, gained traction in the 1930s at institutions like Massachusetts General Hospital, where surgeons performed the procedure alongside dilatation and curettage to interrupt pain transmission from the uterus; by 1946, 111 cases had been completed there, demonstrating moderate relief in select patients with primary or secondary dysmenorrhea. Concurrently, vestibular neurectomy for vertigo associated with Meniere's disease was advanced by Walter E. Dandy at Johns Hopkins Hospital, who began selective procedures via the suboccipital (retrosigmoid) approach in 1932 after initial total eighth nerve sections from 1924; by his death in 1946, Dandy had conducted 692 such operations, the largest series to date, achieving high rates of vertigo control while preserving hearing in many cases.

Advancements in the 20th and 21st Centuries

In the mid-20th century, vestibular neurectomy gained prominence through the extensive work of neurosurgeon Walter Dandy, who performed 692 procedures between 1924 and 1946 primarily to treat vertigo associated with Ménière's disease, achieving low mortality rates with only two fatalities attributed to infection.^[19] Building on such foundational efforts, singular neurectomy emerged as a targeted approach when Richard Gacek introduced the transection of the posterior ampullary nerve in 1974 specifically for managing intractable benign paroxysmal positional vertigo, offering a selective denervation of the posterior semicircular canal to alleviate positional symptoms without broadly affecting vestibular function.^[20] The late 20th century marked a shift toward minimally invasive techniques, with laparoscopic presacral neurectomy introduced in the late 1980s and gaining traction in the 1990s as an alternative to open surgery for central pelvic pain and severe dysmenorrhea linked to conditions like endometriosis.^[21] This approach reduced recovery times and complications compared to traditional methods, with early series reporting pain relief in over 70% of cases.^[22] Concurrently, pulsed radiofrequency ablation emerged in the 1990s as a non-destructive neuromodulation technique for chronic pain management, delivering short bursts of radiofrequency energy to nerves without causing full ablation, thereby minimizing risks like neural damage while providing sustained relief for conditions such as facet joint pain.^[23] Entering the 21st century, robotic-assisted surgery enhanced precision in neurectomy procedures, particularly with the da Vinci system applied to presacral neurectomy since the 2010s, enabling three-dimensional visualization and improved maneuverability in the pelvic cavity for better outcomes in chronic pelvic pain.^[24] Refinements in vidian neurectomy for refractory rhinitis also advanced, with post-2020 endoscopic studies demonstrating 80-90% symptom relief in nasal hypersecretion and congestion among patients unresponsive to medical therapy, attributed to more accurate nerve targeting via transnasal approaches.^[25]

Indications

In Humans

Neurectomy is indicated in humans for various chronic pain conditions, particularly those involving neuropathic mechanisms that are refractory to conservative treatments. In cases of chronic neuropathic pain, such as post-herniorrhaphy neuralgia, selective neurectomy targets the affected nerves to interrupt aberrant signaling and provide relief. For instance, ilioinguinal neurectomy has demonstrated significant pain reduction in patients with chronic groin pain following inguinal hernia repair, with studies reporting lower pain severity at multiple postoperative intervals compared to nerve preservation. Similarly, for trigeminal neuralgia, peripheral neurectomy of the trigeminal nerve branches offers a minimally invasive option, achieving pain control in a substantial proportion of patients unresponsive to medications, with success rates exceeding 80% in long-term follow-up for selected cases.^[26]^[13] Pelvic pain syndromes, including severe dysmenorrhea and endometriosis-related pain, represent another key indication where presacral neurectomy is employed to denervate pain pathways from the uterus and surrounding structures. This procedure enhances cure rates when combined with conservative laparoscopic surgery, particularly in women with midline pelvic pain, leading to over 70% reduction in dysmenorrhea symptoms in responsive patients. Nerve entrapment syndromes, such as intercostal neuralgia or meralgia paresthetica involving the lateral femoral cutaneous nerve, also benefit from targeted neurectomy to alleviate localized neuropathic pain; for example, intercostal neurectomy has shown effectiveness in reducing chronic abdominal wall pain due to nerve impingement, with many patients experiencing substantial improvement.^[27]^[28]^[29] Beyond pain management, neurectomy addresses functional disorders like vertigo in Ménière's disease, where vestibular neurectomy selectively ablates vestibular nerve fibers to control disabling episodes while preserving hearing in most cases. Sympathetic neurectomy, often performed thoracoscopically, is a standard treatment for severe hyperhidrosis, effectively reducing excessive sweating in the palms, axillae, or face with success rates above 95% for primary hyperhidrosis refractory to medical therapy. Vidian neurectomy targets the vidian nerve to treat vasomotor rhinitis, providing long-term symptom relief in patients with intractable nasal hypersecretion and congestion unresponsive to other interventions.^[30]^[31]^[18]^[32] In addition, neurectomy serves as an option for refractory spasticity in the upper limbs, with hyperselective neurectomy—first described in 1912 and refined through modern protocols—focusing on specific motor nerve branches to reduce tone without compromising voluntary function. This approach yields durable improvements in spasticity for conditions like cerebral palsy, enhancing limb positioning and daily activities in pediatric and adult patients. For chronic post-surgical pain, such as ilioinguinal neuralgia after hernia repair, neurectomy achieves 70-90% pain relief in carefully selected cases, underscoring its role in managing persistent neuropathic sequelae.^[33]^[34]^[14]

In Veterinary Medicine

In veterinary medicine, neurectomy is primarily employed to alleviate chronic pain and improve mobility in animals suffering from specific lameness conditions, particularly in equine and bovine species. One common application is the treatment of navicular syndrome, a frequent cause of caudal heel pain and lameness in horses, especially Quarter Horses, where palmar digital neurectomy (in forelimbs) or plantar digital neurectomy (in hindlimbs) severs the respective nerves to interrupt pain signals from the heel region. This salvage procedure is indicated when conservative management, such as shoeing adjustments or anti-inflammatory medications, fails to resolve the lameness associated with navicular bone pathology or deep digital flexor tendon issues. In a retrospective study of 50 horses with MRI-confirmed chronic foot pain treated with palmar or plantar digital neurectomy between 2005 and 2011, the procedure improved or resolved lameness in most cases, though 36% experienced postoperative complications, including residual lameness, painful neuromas, or early pain recurrence.^[35]^[36] Neurectomy also addresses neuromuscular disorders in livestock, notably spastic paresis in cattle, a hereditary condition causing progressive spastic contractions of the gastrocnemius muscle and hindlimb hyperextension. Tibial neurectomy, which transects branches of the tibial nerve innervating the affected muscles, is a standard treatment that preserves normal anatomy while targeting the hyperactive neural response, offering satisfactory long-term outcomes compared to tenotomy. Since 2023, a modified tenectomy approach has emerged as a simpler surgical alternative, involving partial tendon resection to reduce spasms more accessibly and improve animal welfare and performance without the full extent of traditional neurectomy risks.^[37]^[38] Additional indications include proximal suspensory ligament desmitis in horses, where neurectomy of the deep branch of the lateral plantar nerve is performed to relieve chronic pain from ligament inflammation or nerve entrapment in the hindlimb. This procedure targets the nerve's proximity to the suspensory ligament origin, potentially reducing compartment pressure, but carries a risk of neurogenic muscle atrophy in the proximal suspensory ligament's muscular portion, which could alter biomechanics and predispose to further injury.^[39]^[40]

Surgical Procedures

Presacral Neurectomy

Presacral neurectomy is a surgical procedure that interrupts the superior hypogastric plexus, a network of autonomic nerves located in the presacral space, to alleviate central pelvic pain by blocking sensory pathways from the uterus and cervix. The technique typically involves accessing the sacral promontory through an incision below the navel, where the peritoneum overlying the area is incised approximately 1 cm caudal to the aortic bifurcation to expose the plexus. The nerve fibers are then skeletonized using blunt and sharp dissection, followed by coagulation, clipping, or excision of a segment of the plexus to ensure complete transection while preserving adjacent structures like the middle sacral artery and presacral veins.^[41]^[42]^[43] The procedure can be performed via open, laparoscopic, or robotic approaches, each differing in invasiveness and recovery profile. Open presacral neurectomy requires a larger abdominal incision for direct access, typically resulting in a 4- to 6-week recovery period due to greater tissue trauma. In contrast, the laparoscopic approach uses multiple small incisions (e.g., umbilical and suprapubic ports) for insufflation and instrumentation, allowing for a shorter 2- to 4-week recovery with reduced postoperative pain and scarring. Robotic-assisted neurectomy, utilizing systems like the da Vinci platform, offers enhanced precision and three-dimensional visualization through similar port sites, often enabling same-day discharge and a recovery of about 2 weeks. A notable 1990s study involving 176 women (median age 30 years) combined laparoscopic presacral neurectomy with endometriosis excision, demonstrating feasibility and safety in this minimally invasive format.^[42]^[44] This intervention is primarily indicated for severe dysmenorrhea or pelvic pain attributed to endometriosis, particularly when conservative treatments fail and pain is midline-focused. Initial pain relief occurs in 80% to 90% of patients, with studies reporting over 50% reduction in symptoms for 70% to 85% of cases depending on endometriosis stage. However, approximately 13% of patients may experience postoperative constipation due to disruption of sympathetic innervation to the rectosigmoid, though this is often transient and manageable. Long-term efficacy emphasizes patient selection for central pain patterns to optimize outcomes.^[45]^[46]^[47]

Vestibular Neurectomy

Vestibular neurectomy involves the selective surgical severance of the vestibular portion of the vestibulocochlear nerve (cranial nerve VIII) to eliminate vertigo symptoms while preserving the cochlear branch responsible for hearing.^[48] This procedure targets the superior and inferior vestibular nerves, which transmit balance signals from the inner ear, interrupting aberrant vestibular input without affecting auditory function.^[49] The technique requires precise identification and transection of the vestibular fibers within the internal auditory canal or at the cerebellopontine angle, typically under microscopic guidance to avoid damage to adjacent structures like the facial nerve or cochlear nerve. Common surgical approaches include the middle cranial fossa approach, which provides direct access to the superior vestibular nerve through a temporal bone craniotomy; the retrosigmoid approach, involving a suboccipital craniotomy for exposure of the nerve bundle at the pontocerebellar angle; and the suboccipital approach, which offers broad visualization similar to the retrosigmoid but with variations in patient positioning for enhanced access.^[50]^[51] These methods allow for complete sectioning of vestibular afferents while minimizing risks to hearing preservation.^[52] Primarily applied in cases of Ménière's disease or other forms of intractable peripheral vertigo unresponsive to conservative treatments, vestibular neurectomy effectively controls debilitating episodes by ablating the source of vestibular imbalance. Neurosurgeon Walter Dandy performed 692 such procedures between 1924 and 1946 at Johns Hopkins Hospital, reporting high success rates in vertigo resolution, which established the surgery as a standard intervention for the era.^[53] Variations include singular neurectomy, first described by Richard Gacek in 1974, which specifically targets the posterior ampullary nerve innervating the posterior semicircular canal to treat benign paroxysmal positional vertigo (BPPV) confined to that structure.^[54] Additionally, the endoscopic middle fossa approach enhances precision by using endoscopes for minimally invasive visualization and sectioning of the vestibular nerve, reducing the need for extensive bone removal.^[55] As a less invasive alternative, pulsed radiofrequency ablation can sometimes be considered for vestibular nerve modulation without full sectioning.^[56]

Neurectomy for Nerve Entrapment

Neurectomy for nerve entrapment targets compressed peripheral sensory nerves, typically involving neurolysis to release the nerve from surrounding scar tissue or adhesions, followed by partial resection of the affected segment to alleviate chronic pain while preserving motor function where possible. This approach addresses mechanical compression causing neuropathic symptoms, such as burning or tingling, and is reserved for cases refractory to conservative treatments like physical therapy or medications. The procedure minimizes disruption to larger nerve trunks by focusing on distal branches, reducing the risk of widespread sensory loss. In cases of intercostal nerve entrapment leading to chronic thoracic pain, often post-thoracotomy or due to scar tissue, surgical intervention combines neurolysis with neurectomy of the intercostal cutaneous branches. Outcomes show substantial relief, with one study reporting an 84% success rate in reducing chronic postoperative pain in the thoracic region through targeted resection. Similarly, for meralgia paresthetica involving entrapment of the lateral femoral cutaneous nerve under the inguinal ligament, neurectomy after initial neurolysis yields high efficacy, with 94% of patients achieving significant symptom relief, though it may result in persistent numbness in the anterolateral thigh.^[57]^[58] Ilioinguinal neurectomy addresses post-herniorrhaphy neuropathic pain from nerve entrapment in scar tissue, where partial resection follows decompression to target neuromas. Long-term follow-up indicates complete or partial pain relief in approximately 67% of patients, though pain recurrence occurs in about 68% over an average of 35 months, highlighting the need for careful patient selection. For peripheral trigeminal branch entrapment causing neuralgia, particularly in resource-limited rural settings, selective neurectomy of terminal branches like the infraorbital or supraorbital nerves provides effective palliation, with good outcomes in 65% of cases and suitability as a low-resource intervention.^[59]^[60] These procedures are generally performed on an outpatient basis under local anesthesia, posing low risk especially for terminal sensory branches, and are often combined with decompression to optimize nerve gliding and prevent re-entrapment. Pulsed radiofrequency ablation may serve as an adjunct in select cases to modulate pain transmission prior to resection.^[13]^[61]

Risks and Complications

General Risks

Neurectomy, as a surgical procedure involving the intentional transection of a nerve, carries inherent risks associated with nerve interruption, alongside standard perioperative hazards. Common general surgical complications include infection at the incision site, excessive bleeding or hemorrhage, and adverse reactions to anesthesia, such as respiratory depression or allergic responses.^[62] Direct consequences of nerve severance often manifest as sensory disturbances, including numbness or loss of sensation in the denervated area, which is an expected outcome but can lead to functional impairments or patient dissatisfaction. Painful neuroma formation, resulting from disorganized axonal regrowth at the proximal nerve stump, is a known risk after transection. In peripheral neurectomies, incidence is typically 10–30% despite preventive techniques like nerve burial, though higher rates (up to 60% for symptomatic cases) have been reported in contexts like limb amputations. This contributes to chronic neuropathic pain triggered by mechanical stimuli.^[63]^[64]^[65] Additionally, anesthesia dolorosa—a severe deafferentation pain characterized by burning sensations in a numb region—is rare overall but arises in 0.2% to 4% of patients undergoing more extensive nerve ablation procedures such as trigeminal rhizotomy, with lower incidence in targeted peripheral neurectomies.^[66] Interruption of nerves with autonomic components can result in systemic effects, such as dysregulation of visceral functions. For instance, presacral neurectomy has been associated with worsened urinary retention or bladder dysfunction in approximately 19% of patients and constipation in 12.5%, reflecting disrupted pelvic innervation, though these issues improve or remain stable in most cases.^[67] Risk profiles vary by indication: therapeutic neurectomies, performed to alleviate preoperative neuralgia, carry a 35% chance of persistent or recurrent pain, potentially necessitating reoperation in 9% of cases, whereas prophylactic neurectomies—conducted intraoperatively to prevent future issues—exhibit low complication rates, with no reported postoperative neuralgia in recent analyses.^[68]

Procedure-Specific Complications

Procedure-specific complications of neurectomy vary depending on the targeted nerve and surgical approach, often involving disruption of adjacent neural or autonomic functions unique to the anatomical site. In presacral neurectomy, performed to alleviate chronic pelvic pain by severing sympathetic nerves near the sacral promontory, patients may experience autonomic disturbances such as constipation, which developed or worsened in 13% of cases in one study of 100 patients, urinary urgency in 3%, and painless first stage of labor in 2%.^[69] Vestibular neurectomy, aimed at controlling intractable vertigo by sectioning the vestibular portion of the eighth cranial nerve, carries risks to nearby structures in the cerebellopontine angle, particularly with the retrosigmoid approach. Potential complications include hearing loss due to cochlear nerve involvement, reported in up to 20% of cases with significant threshold shifts; persistent tinnitus, which may not resolve if incomplete section occurs; residual dizziness in approximately 20% of patients from incomplete deafferentation; transient facial weakness or paresis, occurring in 15% of cases and typically reversible; and cerebrospinal fluid (CSF) leak, with rates of 5-10% in retrosigmoid procedures, sometimes requiring reoperation.^[70]^[71]^[72]^[73]^[10] For neurectomy in nerve entrapment syndromes, such as meralgia paresthetica involving the lateral femoral cutaneous nerve, recurrence of entrapment symptoms can occur in about 15% of cases due to incomplete resection or neuroma formation at the proximal stump. In veterinary applications, analogous procedures like deep branch lateral plantar neurectomy in horses for proximal suspensory desmopathy risk iatrogenic damage to the suspensory ligament, leading to adhesions or rupture in reported cases.^[74]^[39]

Pulsed Radiofrequency Ablation (as a Neurolytic Alternative)

Pulsed radiofrequency ablation, a minimally invasive technique using thermal energy to disrupt nerve conduction without full transection, is sometimes considered an alternative to traditional neurectomy. It has a lower complication profile than surgical methods, with transient paresthesia affecting less than 5% of patients and resolving within weeks. However, unintended thermal injury to adjacent tissues remains a concern, potentially causing localized neuropathic pain or dysesthesia if heat diffusion exceeds the target zone. As of 2023, emerging guidance techniques like ultrasound continue to reduce these risks.^[75]^[76]^[77]

Postoperative Care and Outcomes

Recovery Process

Immediate postoperative care following neurectomy in humans emphasizes pain management, wound care, and monitoring for complications to promote healing and minimize risks like infection or neuroma formation. Analgesics such as acetaminophen, non-steroidal anti-inflammatory drugs (NSAIDs), or short-term opioids are typically prescribed to control pain and inflammation, with multimodal approaches preferred to reduce opioid reliance.^[78] Patients are monitored for signs of infection, bleeding, or sensory changes, with particular attention to numbness in the denervated area, which requires protection to prevent inadvertent injury. Hospitalization duration varies by procedure and location. Peripheral neurectomies, such as those for Morton's neuroma or trigeminal neuralgia, are often performed outpatient or with a 1-day stay, allowing discharge once stable, with instructions for rest and elevation if applicable.^[79] More invasive procedures, like laparoscopic presacral neurectomy or vestibular neurectomy, may require 1-5 days of inpatient monitoring for neurological status and vital signs.^[80] For trigeminal peripheral neurectomy, follow-up visits are scheduled on postoperative days 2, 7, and 30, then every 6 months up to 3 years to assess pain relief and complications.^[13] Rehabilitation focuses on adapting to sensory deficits and restoring function. Physical therapy, including gentle exercises and gait training, may begin within days for ambulatory patients to prevent stiffness, particularly after lower extremity procedures. Patients are counseled on managing numbness, such as protective footwear for foot neurectomies to avoid ulcers.^[79] Recovery timelines typically range from 1-6 weeks for full return to normal activities, depending on the nerve targeted and surgical approach; for example, Morton's neuroma neurectomy allows partial weight-bearing immediately in a surgical shoe, with sutures removed at 2 weeks and full activity by 3 months.^[79] Follow-up includes clinical exams and, if needed, imaging to evaluate healing and detect neuromas early.^[13]

Long-Term Efficacy and Success Rates

Neurectomy procedures demonstrate variable long-term efficacy in providing sustained pain relief, typically ranging from 70% to 95% in carefully selected patients across different indications, though outcomes depend on the specific nerve targeted and underlying pathology. For instance, in cases of presacral neurectomy for endometriosis-related pelvic pain, more than 50% reduction in symptoms was reported in 74% of patients for overall pelvic pain, 61% for dysmenorrhea, and 55% for dyspareunia, with follow-up extending up to 72 months postoperatively.^[46] Similarly, vidian neurectomy for allergic or vasomotor rhinitis yields significant and durable improvements, with visual analog scale scores for nasal symptoms dropping from preoperative levels of approximately 7-8 to 2.6-3.7 at three years post-procedure, alongside enhanced quality-of-life metrics in domains such as sleep and emotional function. In Morton's neuroma, long-term pain relief reaches 80-90%, though up to 35% of patients may experience residual discomfort.^[81] These success rates highlight neurectomy's role in achieving substantial, multi-year symptom control when applied to appropriate candidates. Key factors influencing long-term durability include patient selection criteria, such as prior abdominal surgery, ongoing use of pain medications, presence of paravertebral tender points, and response to diagnostic nerve blocks, which can predict treatment failure with odds ratios ranging from 1.8 to 3.7. Younger age has been associated with potentially higher recurrence risk in certain contexts, such as ilioinguinal neurectomy for post-herniorrhaphy pain, where overall recurrence approached 68% at a mean follow-up of 35 months, though complete or partial relief was achieved in 67% of cases, correlating with improved quality of life.^[82] Recurrence rates in therapeutic neurectomies generally fall between 20% and 35%, as seen in 23% of posterior neurectomies for anterior cutaneous nerve entrapment syndrome at 58 months, often occurring after a median pain-free interval of 8 months. Prophylactic neurectomy, such as ilioinguinal nerve excision during hernia repair, lowers the incidence of chronic groin pain to 0-7.5% at six months compared to 10-22.5% with nerve preservation, based on 2022-2023 prospective data.^[83] Illustrative studies underscore these patterns; in human anterior neurectomy for chronic abdominal pain, approximately 50% achieved ≥50% relief at long-term follow-up, with higher success (61%) in recurrent versus ongoing pain cases.^[82] These findings emphasize the procedure's value in reducing neuralgia over years while highlighting the need for diagnostic validation to optimize selection and mitigate recurrence.

Applications in Veterinary Medicine

Use in Horses

Neurectomy in horses primarily involves palmar or plantar digital neurectomy, a surgical procedure targeting the palmar (forelimbs) or plantar (hindlimbs) digital nerves to alleviate chronic foot pain. This technique is most commonly applied to treat navicular disease or chronic heel pain that has not responded to conservative therapies such as shoeing modifications, anti-inflammatory medications, or corrective farriery. The procedure typically entails making a small incision over the pastern region to expose and sever the digital nerves, often using the guillotine method where a 2-cm incision is made dorsal to the flexor tendons, the nerve is isolated, and a 1-2 cm segment is removed to prevent regeneration.^[84]^[4] Indications for palmar/plantar digital neurectomy are limited to cases of long-term lameness originating from the foot, particularly when magnetic resonance imaging (MRI) confirms lesions such as deep digital flexor tendon damage or navicular bone pathology unresponsive to medical management. In a retrospective study of 50 horses treated between 2005 and 2011, the procedure was performed on animals with chronic foot pain verified by MRI, serving as a salvage option after failure of other interventions. This approach is considered a last-resort measure due to its irreversible nature and potential for complications, reserved for severe cases where quality of life is significantly impaired.^[85] Outcomes of the procedure show variable but often temporary relief, with 80% of horses in the aforementioned study returning to previous athletic use for a median duration of 20 months (range: 12-72 months), though 36% (18/50) experienced complications including residual lameness, painful neuromas, or early recurrence of heel pain. Broader reviews indicate that approximately 65-70% of horses achieve lameness resolution post-neurectomy, typically lasting 12-18 months before potential nerve regrowth or symptom return. A 2024 study on 85 horses undergoing palmar digital neurectomy with dorsal-to-palmar branch neuroanastomosis to prevent neuromas found no reduction in neuroma formation, with 95% initial lameness resolution but only 68% remaining sound at 1 year and 22% complications.^[85]^[4]^[86] Risks include seroma formation at the incision site, curb-like swellings from post-operative inflammation, and damage to the suspensory ligament or deep digital flexor tendon due to loss of sensation leading to self-trauma, emphasizing the need for strict stall rest and bandaging in the recovery period.^[85]^[4]

Use in Other Animals

In veterinary medicine, peripheral neurectomy is employed in dogs to address chronic pain and lameness associated with peripheral nerve sheath tumors or injuries, where medical management proves refractory. For instance, ulnar neurectomy has been performed to excise neurofibromas in the carpal canal, resulting in resolution of chronic thoracic limb lameness without recurrence at 11 months postoperatively.^[87] Similarly, partial neurectomy for malignant peripheral nerve sheath tumors enables limb-sparing surgery, eliminating pain and lameness on long-term follow-up.^[88] These procedures often target sensory nerves, producing permanent desensitization of the affected area to alleviate ongoing discomfort.^[89] Non-selective cutaneous sensory neurectomy serves as an alternative for managing chronic self-mutilation lesions in dogs following arthrodesis, a complication driven by neuropathic pain. Performed under general anesthesia via a proximal skin incision to transect relevant sensory branches, the technique resolves self-trauma within 24 hours, with wounds healing uneventfully and no recurrence over periods up to 3 years.^[90] Such interventions are typically straightforward, allowing for outpatient recovery in suitable cases, though general anesthesia is required.^[91] In cattle, neurectomy addresses spastic paresis, a hereditary neuromuscular disorder causing hindlimb spasms and impaired mobility. Partial tibial neurectomy, which involves resecting a segment of the tibial nerve to denervate the gastrocnemius muscles, has been refined in recent applications, such as a 2023 case in a Simmental calf where a 1 cm nerve section was removed via a 15 cm incision, leading to immediate resolution of spasms and pain.^[92] This approach targets the underlying neuromuscular hyperactivity by denervating the affected muscles, restoring gait and enhancing welfare; alternative procedures like tenectomy address the tendons and may offer different advantages in access and risks.^[92] Outcomes for neurectomy in small animals like dogs demonstrate low complication rates, with case series reporting no postoperative issues such as neuroma formation in treated cohorts.^[90]^[93] In livestock, emerging applications for paresis yield high efficacy, with partial tibial neurectomy achieving good to excellent results in over 80% of cases, including 83% success in a study of 113 Belgian Blue calves where most exhibited normalized function without severe hyperflexion.^[94]^[38]
