[Hearing results following tympanoplasty (author's transl)].

Tympanoplasty can produce a stable hearing improvement in many patients with chronically inflamed ears. In our series of patients, severe damage to the inner ear following surgery occurred in 3% patients and was associated with a hearing loss of greater than 15 dB. Complete hearing loss occurred in 0.2% of the patients reviewed. In patients with an intact ossicular chain, simple myringoplasty is associated with the best results. Loss of the stapedial arches affects the postoperative air-bone gap most significantly, while loss of the manubrium mallei or the creation of a radical mastoid cavity are additional negative factors. Extent or localization of ossicular fixation has no direct influence on hearing results when appropriate ossicular reconstruction is performed.
