Monitoring auditory evoked potentials during acoustic neuroma surgery. Insights into the mechanism of the hearing loss.
By recording cochlear, auditory nerve, and brainstem potentials while monitoring acoustic neuroma (vestibular schwannoma) surgery, different patterns of changes occur that suggest different causes for the hearing loss. Having identified the putative mechanism of the hearing loss, suggestions are made about how such hearing loss might be avoided.
