OBJECTIVE: The present study proposes an evolution of an intraoperative video-based facial nerve monitoring system for otologic and otoneurosurgical procedures in comparison with classical electromyographic (EMG) monitoring method.
STUDY DESIGN: Single-subject design study.
SETTING: Tertiary referral center, university clinic.
PATIENTS: Fifteen patients undergoing a translabyrinthine approach for removal of 2 cm or less acoustic neuroma.
INTERVENTION: Intraoperative monitoring during acoustic neuroma removal.
MAIN OUTCOME MEASURES: Measurement of mouth angle displacement and EMG peak amplitude at different stimulation intensities were measured and compared to evaluate the validity and reliability of the proposed new system.
RESULTS: The electrophysiologic method has been shown to be slightly more sensitive, although it shows limitations especially in terms of electrical artifacts during cauterization, totally masking the EMG monitoring.
CONCLUSION: The present version of video system can be considered as valid and reliable as EMG; its main advantages are the absence of electrical artifacts, less invasivity, and much less cost.
