Stapedotomy: the JB Causse technique.
The Jean-Bernard Causse technique of stapedotomy, derived from Jean René Causse "Teflon-interposition" technique, offers an optimum reconstitution of the function of the annular ligament of the stapes footplate. The quantity and quality of hearing depend significantly, among other things, on the function of the stapes footplate annular ligament. Its impedance keeps the perilymph motion within a physiological acoustic amplitude quantum level unless the movements are so excessive as in barotrauma and acoustic trauma which would have overworked even the annular ligament of a normal footplate. This surgical technique permits snorkling, scuba-diving, airplane landing, eustachian tube dysfunction after surgery as in a normal individual who did not undergo otosclerosis surgery. A comparative study on the postoperative hearing based on 3,000 out of 14,000 cases done by J C Bausse technique, 127 cases with small fenestra technique and 267 cases of complete platinectomy showed too large stapedotomy gives poor high tones and too small stapedotomy poor low tones. Five year follow-up on the hearing loss indicated that total platinoctomy has 1.7 times more alteration of 4 kHz frequency in comparison to the technique reconstituting the annular ligament. Yearly audiogram to check the evolution of cochlear otospongiosis may lead the surgeon to prescribe sodium fluoride if the mid-frequencies are deteriorating and vascular drugs if the high pitch frequencies are deteriorating.
