[Tinnitus and intrapetrous cholesteatoma].

The authors exposed his surgical experience with 10 cases of intrapetrous cholesteatomas specially in view of clinical diagnosis. In fact, no special clinical signs were found except perhaps "facial tic" and intolerable tinnitus in this study. They emphasised upon the necessity of evoked potentials, CT-Scan with contrast and eventually MNR examination specially usefull in cholesteatoma when some doubt subsists.
