Stapedotomy performed with microdrill technique for otosclerosis : hearing results and complications

Abstract EN

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 performed in the last 6 years was reviewed.

The technique was evaluated using audiometric results (air-bone gap closure, pure tone audiogram) and the rate of complications.

The stapedotomy is performed 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 supra-structure is down fractured with a rightangled pick.

A fenestration is made in the central area of the footplate using the microdrill.

In these surgeries, the teflon prosthesis was used.
