[Study of 288 stapedectomies performed between 1986 and 1991]

A review of 288 stapedectomies performed between 1986 and 1991 was carried out. Pre- and post-surgical (within six to nine months) audiometries were studied, analyzing the 250 Hz, 500 Hz, 1,000 Hz, 2,000 Hz and 4,000 Hz frequencies. No significant differences between age and sex, type of prosthesis or final auditive gain were found. Patients were distributed in six groups according to their initial audiometry, achieving higher auditive gain those with and worse initial audition.
