[Our surgical approach in the treatment of otosclerosis over the past 10 years].

Abstract

The most frequently used technique of surgery of otosclerosis used during the past ten years in the Central Military Hospital was Schuknecht's technique of wire and fat. 575 thus operated patients account for 89.4% of the total number of 643 operations. A compensation of the bone reserve to 0-10 dB was achieved in the late results of 56.3% of the operated patients, in another 30% there were auditory gains of speech frequencies, on average above 10 dB. Favourable late results were thus achieved in 86.3% of the operated patients, deterioration of hearing was recorded in 4.8% (13 operated patients). Pistons of Schuknecht's type were used in 23 patients with the obliterating form of otosclerosis. As to late results, in 21 of the evaluated patients compensation of the bone reserve to 0-10 dB was recorded in 28.6%. The mean auditory gains as regards speech frequencies higher than 10 dB were achieved in 47.6%. Favourable late results were thus recorded in 76.2% of operated patients with the obliterating form of otosclerosis. Deterioration of hearing occurred in this group in one operated patient (4.8%).
