Peripheral Nerve Surgery: Ulnar, Radial, and Facial Nerve Repair

A doctor who operates on nerves outside the brain and spinal cord — the peripheral nerves — is generally referred to as a peripheral nerve surgeon. In the upper limb, this overlaps closely with hand and reconstructive plastic surgery.

Ulnar Nerve Surgery (Cubital Tunnel)

The ulnar nerve can become compressed at the elbow — often called cubital tunnel syndrome — causing numbness in the ring and little fingers. Surgery decompresses or repositions the nerve, and a splint or cast is sometimes used afterward to protect the area while it heals.

Radial Nerve Surgery

The radial nerve controls wrist and finger extension; injury or compression can cause wrist drop or numbness on the back of the hand. Surgery may involve decompression or, after trauma, nerve repair — with incision placement planned to keep resulting scarring as inconspicuous as possible.

Facial Nerve Surgery

Facial nerve repair and reconstruction is a distinct area within reconstructive plastic surgery, addressing facial nerve injury or paralysis — restoring as much facial movement and symmetry as possible, often as part of a broader reconstructive plan.

The Common Thread: Decompression and Repair

Whether it's the median nerve at the wrist, the ulnar nerve at the elbow, or the radial or facial nerve, most peripheral nerve procedures fall into two broad categories: decompressing a nerve that's become trapped or compressed, or repairing a nerve that's been directly injured.
