[Successful decompression of the acoustic nerve after postarachnitic hearing damage (author's transl)].

Abstract

Arachnitic adhesions of the pontine angle can damage the VIIIth cranial nerve to complete hearing loss. If there exists only a circumscript damage of the myeline sheet, this functional loss is reversible after decompression of the nerve. Preoperatively, the electrocochleography and the cisternoscopy discover this type of nerve damage and so, the probability of the postoperative hearing recovery is quite predictable.
