How do you heal facial nerves?

In many cases of facial nerve weakness, providers may prescribe an oral steroid that will help to reduce inflammation (irritation) of the facial nerve. Multiple research studies have shown that high doses of medication, started within 72 hours of the paresis (weakness) or paralysis, will improve chances for recovery.

Can you fix nerve damage in face?

There are three basic approaches to facial nerve repair: direct nerve repair, cable nerve grafting or nerve substitution. Direct nerve repair is the preferred option whenever possible and is performed by removing the diseased or affected portion of the nerve, then reconnecting the two nerve ends.

  1. Electromyography (EMG): An EMG measures a muscle's electrical activity when stimulated and how fast the muscle responds. ...
  2. CT or MRI scans: These tests can help determine other causes of facial nerve damage, such as a fracture, infection, or tumors in the head or neck area.
