A neurectomy is a surgical procedure that removes all or part of a nerve to stop it from sending pain signals. It’s typically reserved for chronic pain conditions that haven’t responded to less invasive treatments, and it works by permanently interrupting the nerve pathway between a painful area and the brain. The trade-off is straightforward: you lose sensation in the area that nerve supplies, but you also lose the pain.
How a Neurectomy Works
Nerves carry signals in two directions: sensory signals travel toward the brain (telling you what you feel), and motor signals travel away from the brain (telling muscles to move). Neurectomy targets purely sensory nerves, meaning small peripheral nerves that only carry feeling, not movement. This is a critical distinction. Cutting a nerve that controls muscle function would cause paralysis in that area, so surgeons limit the procedure to nerves where the only consequence is numbness.
During the procedure, the surgeon identifies the problem nerve, cuts it, and then relocates the remaining stump into nearby muscle or soft tissue. This relocation step matters because a cut nerve end left exposed near bone or scar tissue can form what’s called a stump neuroma, essentially a painful knot of nerve tissue that recreates the original problem. Burying the cut end in muscle helps prevent that.
Some neurectomies are performed under local anesthesia as outpatient procedures, while others require general anesthesia depending on the location and complexity. A triple neurectomy for groin pain after hernia repair, for example, can be done under local anesthesia in a single operation.
Conditions Treated With Neurectomy
Neurectomy isn’t a first-line treatment for anything. It’s the option that comes after medications, injections, physical therapy, and sometimes other surgeries have failed. The most common conditions where it’s used include:
- Morton’s neuroma: A thickening of nerve tissue between the toes that causes sharp, burning pain in the ball of the foot. Neurectomy for this condition has an 82% success rate, with some studies reporting long-term relief as high as 93%.
- Post-hernia repair pain: Chronic nerve pain after inguinal hernia surgery is one of the most studied indications. About 90% of patients experience pain improvement after neurectomy, with only a 9.4% complication rate.
- Endometriosis-related pelvic pain: A presacral neurectomy cuts the nerves that supply the uterus and cervix to relieve midline pelvic pain. When added to standard endometriosis surgery, it reduces the risk of ongoing pain by 57% compared to surgery alone. At one year, only about 9% of patients who had the neurectomy reported treatment failure, compared to 25% without it.
- Facial nerve pain: Neurectomy can be particularly useful for trigger-point areas on the face where a small sensory nerve is the clear source of pain.
- Chronic rhinitis: For persistent runny nose and sneezing that doesn’t respond to medication, neurectomy of the posterior nasal nerve has shown significant improvement in symptoms, with particular benefit for sneezing.
What Recovery Looks Like
Recovery varies significantly depending on where the neurectomy is performed. Foot neurectomies, among the most common, offer a useful example of the general timeline.
For the first week after surgery, you’ll be at half your normal weight-bearing capacity and will need crutches or a walker. You’ll keep the foot elevated as much as possible. At three to four weeks, you can start increasing weight on the foot and weaning off the crutches. You’ll transition back to a regular shoe around this time, though it will likely need to be a size larger because of swelling.
Low-impact exercise like cycling, swimming, or using an elliptical becomes an option at four to six weeks. High-impact activities like running or jumping are off limits until three months post-surgery. Full resolution of soreness and swelling at the surgical site takes three to six months. Many patients find that shoe choices remain limited for a while. In Morton’s neuroma cases, 71% of patients reported ongoing difficulty wearing tight or fashionable shoes even after a successful procedure.
Groin and pelvic neurectomies have different recovery profiles, but the general pattern holds: several weeks of restricted activity followed by a gradual return to normal over two to three months.
Risks and Complications
The most common side effect is a change in sensation. About 5% of patients develop hypersensitivity or unusual skin sensations in the area after surgery. This might feel like tingling, heightened sensitivity to touch, or an “electric” quality to the skin. For most people this fades over time, but it can persist.
Numbness in the area supplied by the removed nerve is expected and permanent. This is the intended effect, not a complication, but it’s worth understanding clearly before surgery. If a nerve supplying part of your foot is removed, that patch of skin will have no feeling going forward.
About 3.4% of patients find that their pain actually worsens after neurectomy. This can happen when the cut nerve end forms a stump neuroma, essentially creating a new source of pain at the surgical site. The technique of burying the nerve stump in muscle was developed specifically to reduce this risk, but it doesn’t eliminate it entirely.
Pain Can Return
One reality of neurectomy that catches some patients off guard is that nerves can regenerate. The recurrence rate after a successful neurectomy is approximately 20%. Researchers have confirmed this by finding nerve tissue during repeat surgeries in patients whose pain returned, suggesting the cut nerve actually grew back.
When pain does recur, the timeline varies widely. In one study tracking patients after neurectomy for abdominal nerve pain, recurrences appeared at 9, 10, 12, 16, and 72 months after surgery. So while most recurrences show up within the first year or two, pain can return years later.
The encouraging finding is that a repeat neurectomy can still work. Some patients in that study underwent up to five repeat procedures and still achieved pain relief. The fact that the nerve regrows is what makes it possible to cut it again successfully.
Neurectomy vs. Less Invasive Alternatives
Before committing to surgical neurectomy, many patients are offered less invasive nerve-targeting procedures. Radiofrequency ablation uses heat to damage nerve tissue, and cryoablation uses extreme cold. Both can be done in an office setting without general anesthesia.
For chronic rhinitis, both surgical neurectomy and in-office ablation produced significant improvements in symptoms. Neurectomy showed a greater reduction in sneezing specifically, but overall symptom scores were similar between the two approaches. One notable finding: patients who had ablation first and then moved to neurectomy didn’t see clear additional improvement, suggesting that if ablation works partially, a follow-up neurectomy may not add much benefit.
For facial nerve pain like trigeminal neuralgia, less invasive percutaneous (through-the-skin) procedures are often preferred for older patients or those who aren’t good candidates for open surgery. These shorter procedures can be done as day cases, and many elderly patients prefer them over a longer, more involved operation. Open surgical approaches are typically offered to patients under 75 who are in good health.
Neurectomy in Veterinary Medicine
Neurectomy isn’t limited to human medicine. It’s a well-established procedure in horses, where palmar digital neurectomy is used to manage pain from navicular disease, a chronic condition affecting a small bone in the hoof. The procedure relieves pain by cutting the sensory nerves to the back of the foot, allowing the horse to move comfortably again. Veterinarians note that the procedure carries real risks and isn’t considered benign, so it’s used only after other treatments have been exhausted.
