Objective: This paper describes the technique of low-speed microdrilling during stapedotomy in individuals with otosclerosis. It also evaluates the hearing results and complications using this technique to perform stapedotomy.
Material and method: A retrospective study of 45 stapes surgeries done in the past 6 years were reviewed. The technique was evaluated using audiometric results (air-bone gap closure, pure tone audiogram) and the rate of complications. The stapedotomy is made with drilling the posterior crus of the stapes using the microdrill as close to the footplate as possible. The incudostapedial joint is separated with a joint knife, and the suprastructure is down fracturedwith a right-angled pick. A fenestration is made in the central area of the footplate using the microdrill and the perforator. In these surgeries, the Teflon prosthesis was used.
Result: The postoperative results using microdrill technique demonstrated improvement in hearing. Microdrill stapedotomy showed to be a save procedure.
