Abstract

Objective

The current study evaluated the effectiveness of endoscopic transcanal facial nerve decompression in patients with post-traumatic facial nerve paralysis.

Methods

This retrospective study included 10 patients with post-traumatic complete facial nerve paralysis who underwent endoscopic transcanal facial nerve decompression. The surgical technique was explained step by step, and the surgical complications, hearing status and facial nerve function 12 months post-operatively were reported.

Results

Endoscopic transcanal facial nerve decompression allowed exposure of the geniculate ganglion to the mastoid segment. The facial nerve function improved from House–Brackmann grade VI to grades I and II in 8 of 10 (80 per cent) patients, and 2 patients experienced partial recovery (House–Brackmann grades III and IV). No severe complication was reported.

Conclusion

Endoscopic transcanal facial nerve decompression, involving the nerve from the geniculate ganglion to the mastoid segment, is a safe and effective approach in patients with post-traumatic facial nerve paralysis.
