Early hearing evaluation after microdrill stapedotomy.
Stapedectomy is known to give good results for otosclerosis. In this study, an audiometric evaluation of patients who underwent small-opening stapedotomy has been carried out at an early stage (3 and 5 days after surgery), and 1 month after surgery. At day 5 almost 60% of the patients showed a good functional result (mean residual post-op air conduction/pre-op bone conduction gap within 5 dB). While the timing of 4 kHz recovery overlapped that of the lower frequencies, recovery for 8 kHz was evident only at day 30, and was less likely to occur than for 4 kHz.
