Abstract

A patient with neurofibromatosis two (NF2) presented with bilateral acoustic neuroma. Pre-operative audiometry revealed a dead right ear and severe left-sided sensorineural hearing loss. Following surgical removal of the larger right acoustic neuroma we have documented a sensorineural improvement of 45 dB in the contralateral ear on pure tone audiometry, which as far as the authors are aware has not previously been described.
