[Pre- and postoperative hearing thresholds and brain stem potential in acoustic neuroma. Is neuroma-induced hearing loss reversible?].
Following acoustic neuroma excision through the middle fossa route hearing was maintained in 30% (8.8% of all patients with acoustic neuroma) within 20 dB compared with preoperative thresholds. Acoustic evoked brain stem responses had the tendency to normalise within 2 to 6 months following surgery. In individual cases hearing function was improved.
