Cochlear deafness in the presentation of a large acoustic neuroma.
It is exceptional for a large tumour, as presented, to present a cochlear pattern of hearing loss. Only a rigid adherence to a battery of audiological, vestibular and radiological tests can exclude neuroma. The possibility of hearing conservation in neuroma surgery (Clemis et al., 1981) demands further understanding of the mechanism of cochlear damage produced by CP angle tumours.
