title: Initial experience of peroperative electrocochleography monitoring in stapedectomy.
abstract: Clinical experience of intraoperative ECochG monitoring during stapes surgery is reported. Selected surgical phases have been taken into consideration, laying particular stress on the phase corresponding to the opening of the labyrinthine spaces. Compound action potential (CAP) amplitude and latency showed, a supposed, an inversely proportional relationship in most of the cases. Abnormal findings were also recorded in some patients, thus giving rise to different electrophysiological hypotheses. A proposal for an "in vivo" model for the study of the electrophysiological changes due to the opening of labyrinthine spaces is made.
