Objective:
To evaluate the effectiveness and safety of the endoscope-assisted microscopic view in hemifacial spasm.

Methods:
A total of 26 patients underwent endoscope-assisted microscopic facial nerve microvascular decompression through retrolabytinthine approach from January 2013 to December 2016 were retrospectively reviewed in Ear Institute, Shanghai Jiaotong University School of Medicine. The pre- and post-operative Cohen Classification for hemifacial spasm, House-Brackmann Grade for facial nerve function, hearing level and complication rates were reviewed.

Results:
Satisfactory symptom-relief was achieved in all patients. No facial paralysis and other lower cranial nerve dysfunction were observed. No hearing loss was observed. No postoperative complications such as cerebrospinal fluid leakage occurred during follow-up. No recurrence was seen during follow-up.
Conclusions An angled endoscope as an adjunct to microscope contributes to the diagnosis of the offending vessel in the REZ of the facial nerve and avoid injury of adjacent structures to decrease the complication rates and improve the postoperative quality of life
