In 2000, a new classification system of ossicular reconstruction was proposed bythe terminology committee of Otological Society of Japan. Of the ossicular reconstruction, the type III tympanoplasty is a most common procedure. In this article, we evaluate the hearing results after the type III stapes columella tympanoplasties (III-c) and the type III incus interposition tympanoplasties (III-i) that were performed in our division. Total subjects were 128 patients who received either III-c (84 cases) or III-i (44 cases) and had subsequent follow-up period not less than 6 months. Favorable hearing results were observed in 77.3% of the patients who underwent III-c, and 79.5% of III-i.
Furthermore, the comparison and evaluation of these data with the hearing results after the type IV tympanoplasties are shown.
