7 cases of congenital aural atresia and stenosis

Abstract

We have experienced 7 cases of congenital aural atresia or stenosis in the past 10 years. They include 3 males and 4 females, and all of them are under 10 years old except for one case (47-year-old man). We performed both a canalplasty and a tympanoplasty at the same time in all cases. We have treated 3 cases as tympanoplasty type I, 2 cases as tympanoplasty type II -c, 1 case as tympanoplasty typeIV-c, and 1 case without reconstruction of ossicle, The major cause of hearing loss after the operation was lateralization of the tympanic membrane and fixation of a collumela. We performed re-operations in 2 cases by establishing a bony annulus or replacing the collumela with an artificial ossicle. If the handle of malleus is there, the interdigited method is effective to prevent lateralization of the tympanic membrane.
