The effects of 4-aminopyridine and methylprednisolone on recovery of the facial nerve crush injury.

Objective: 4-Aminopyridine (4-AP) is a potassium channel blocker that enhances nerve excitability. In this study, rat models that have facial nerve crush injury (FNCI) were grouped and treated with methylprednisolone (MP), 4-AP, and a combination of these two drugs. Electrophysiologic and histopathologic outcomes of these groups will be compared with a control group.
