Peripheral nerve surgery for the treatment of postherpetic neuralgia.

Postherpetic neuralgia is a chronic pain condition that develops in some patients after the resolution of herpes zoster, and has no medical cure. Medications used to treat chronic pain do not hasten resolution of the disorder and may impair function. In this brief case report, we describe our experience with excision and implantation to muscle of peripheral sensory nerves in the affected dermatomes as a novel surgical treatment to reduce pain and improve quality of life for patients with this condition. Of the 3 treated patients, all had resolution of chronic pain after surgery. It is concluded that peripheral nerve surgery offers a promising option to improve pain and quality of life in postherpetic neuralgia patients, without affecting systemic functioning.
