[Preservation of auditory function in the excision of acoustic neuroma].

Selection criteria for the preservation of auditory function during excision of acoustic neurinoma have been defined for a long time, and the means for a successful achievement of such a goal are widely known. Recruitment of special patients, for whom maintenance of an even deeply altered hearing capacity constitutes a requisite for continuation of professional work has lead us to extend indications for the pre- and retrosigmoid approaches recommended by J.M. Sterkers. The authors present a series of 16 patients, in which a single case of cophosis was deplored.
