[Hearing results of cholesteatoma middle ear surgery using open and closed techniques]

The author described an analysis of hearing results in open and closed tympanoplasties of ear cholesteatoma. 172 patients were operated upon. 73 have had open and 99 closed technique. The better hearing results were obtained in closed surgery, but not so good as expected. The unsuccessful hearing results were two times frequent in open surgery. We prefer the two step closed intervention after all pathologic lesions being eradicated.
