Abstract

Introduction

This study aims to review the causative factors and various treatment modalities for iatrogenic facial nerve palsy.

Methods

This is an analytical prospective study carried out at a tertiary care hospital in Department of ENT at Seth GS Medical College & KEM Hospital between Jan 2013 to Jan 2017 with a sample size of 12 patients.

Results

6 patients developed iatrogenic facial nerve palsy after mastoidectomy, 3 secondaries to parotidectomy, 1 post stapedotomy, 1 after cochlear implant and 1 secondary to acoustic neuroma excision. 7 out of them were surgically re-explored and rest were given conservative management. 10 patients had partial recovery and 2 of them have complete return of facial nerve function.

Conclusion

There is no substitute for thorough knowledge of anatomy of facial nerve during otologic surgeries. In cases of iatrogenic facial nerve palsy surgical exploration should be considered when there is an immediate onset complete facial nerve palsy.

Recommendation

Intraoperative facial nerve monitoring is a recommended technique during mastoidectomy, despite the fact that it cannot replace anatomical identification of the facial nerve or surgical expertise
