Correlation of Facial Nerve Function and Electrical Stimulation During Vestibular Schwannoma Surgery.

ABSTRACT:

Objective

The aim of the present study is to identify electrophysiological parameters in facial nerve monitoring that provide the best predictive values in vestibular schwannoma surgery.

Study design

Retrospective study.

Setting

Tertiary care hospital.

Methods

In total, 76 patients undergoing translabyrinthine vestibular schwannoma resection were included. Facial nerve monitoring was conducted with free-running electromyography and direct electrical stimulation. Direct electrical stimulation protocol was predicated on a constant-current delivery at the root exit zone before and after tumor excision; specifically, recordings were made with increasing current settings: 0.05, 0.1, and 0.3 mA. The maximum amplitude measured from either of the two muscle groups was
