Encoche De Carhart Et Chirurgie Stapédienne

Abstract

The authors, in the light of an observation of a Carhart notch recovered after a bilateral otosclerosis operated on at the same time during the same stay in hospital, emphasize on one hand the possibility to forsee the postoperative gain with the modern techniques of deafness surgery in otosclerosis by adding to the audiometric Rinne the otosclerotic Carhart notch, (rectified by Fournier according to the calibration of european audiometers); on the other hand the absence of unknown elements owing to the contro-lateral ear, that does not have an effect at all upon the rate of the post-operative B.C. of the ear operated on. The techniques through which those results have been achieved, are stapedectomy with vein graft and polyethylene tube, and “teflon-interposition”.
