[The influence of age and previous thresholds on stapedectomy results].
This is a retrospective study dealing with 719 primary stapedectomies and 48 reoperations done between 1975 and 1993 by the AA. of the paper. They consider the audiometric tracings before and after surgery (6 and 12 months). Frequencies analyzed were 250 Hz, 500 Hz, 1000 Hz, 2000 Hz and 4000 Hz; the air-bone gap; and modifications of bone thresholds. The patients were ranged in groups according the ages and previous bone thresholds. Thereafter an analysis aiming to a comparison of surgery results en each group was contemplated. The age resulted without influence on the postoperative gap neither in modifications of bone conduction. The previous bone thresholds nor influencing the final gap. Conversely there are significative differences (P > 0.01) regarding the modifications of bone conduction.
