Study Summary
The Auditory Nerve Test System (ANTS) is a novel device that stimulates the auditory nerve much like a cochlear implant. The purpose of this study is to demonstrate feasibility of the ANTS during translabyrinthine surgery for vestibular schwannoma resection. If the auditory nerve is kept intact, then the patients will also receive a cochlear implant at the same time potentially alleviating the morbidities caused by a vestibular schwannoma and asymmetric sensorineural hearing loss.
Primary Outcome
Reliability of electrically-evoked direct auditory nerve monitoring at the brainstem (eCNAP) and far-field auditory brainstem response (eABR). The auditory nerve signal will be monitored before, during, and after vestibular schwannoma resection. Elements like signal amplitude, latency, and preservation of eABR waveforms III and V will be measured.
