[Technics and indications of limited petrosectomy. Value of the combined transcochlear and infratemporal approach].

The authors describe the extended trans-cochlear approach and define its indications on the basis of a series of 10 cases operated by the transcochlear approach, 6 of which were extended. This approach has a well defined indication between the trans-cochlear approach described by W. House and the infra-temporal approach described by Fish.
