Phenol or alcohol nerve ablation is a minimally invasive procedure used to reduce chronic pain or muscle stiffness caused by nerve-related conditions. It works by injecting phenol or alcohol into specific nerves, blocking pain signals or reducing muscle tightness. This treatment is often used for trigeminal neuralgia, postherpetic neuralgia, intercostal neuralgia, or severe muscle spasticity from cerebral palsy, stroke, or spinal cord injuries.

The goal is to provide at least six months of relief, though nerves do regenerate, and repeat treatments may be needed.

Most procedures are done under local anesthesia, but sedation may be used if necessary. Fluoroscopy or ultrasound imaging helps guide the needle precisely to the targeted nerve. Once confirmed, the chemical is slowly injected to block pain signals.

Alternatives include botulinum toxin injections for spasticity or surgical nerve resection for longer-lasting relief.

Risks are low but may include temporary burning or tingling at the injection site. Rare but serious risks include nerve damage or systemic effects, particularly with phenol, which is processed by the liver. This procedure may not be suitable for patients with advanced liver disease.

You’ll be monitored after the procedure for any immediate effects. Pain relief can take a few days to weeks and typically lasts several months. Some patients require repeat treatments for ongoing relief.
