The effect of n‐acetyl‐cysteine on recovery of the facial nerve after crush injury

Objective Facial nerve dysfunction can vary in severity and recovery is dependent on the character of the injury. N‐acetyl‐cysteine prevents oxidative stress and cellular damage, and its use in the setting of nerve dysfunction from crush injury has not yet been established. In this study, rats with facial nerve crush injury will be treated with n‐acetyl‐cysteine or control and functional recovery and electrophysiologic outcome will be compared.
