Abstract

Introduction: Introduction: -The facial nerve (FN) is at risk for an injury through its course by accidental or surgical trauma. FN trauma management is a challenging as spontaneous recovery is unpredicted.
Patient and Methods: A prospective study was conducted on patients (22 cases) with posttraumatic LMN FN paralysis (accidental /iatrogenic etiology) who were candidates for surgical intervention.
Results: At final post intervention (1 year) follow-up, 7/22 patients (31.82%) had mild dysfunction (House–Brackmann (HB) grade II), 12/22 cases (54.55%) had a moderate dysfunction (HB grade III), 2/22 cases (9.09%) had moderately severe dysfunction (HB grade IV) and 1/22 case (4.55%) had total dysfunction (HB grade VI).
Conclusion: The outcome of the FN function following the surgical repair is significantly better in cases with accidental trauma compared to those with surgical trauma. This means that the insult of the surgeon on FN is much worse than accidents.
