It is well known that the inner ear and stapes function are remained normal and the hearing improvement can be expected by meatoplasty, myringoplasty and ossiculoplasty in the patients with congenital atresia or stenosis of the ear canal. The patients who underwent meatotympanoplasty are expected for having good influence on daily life because of the patients being youths.
Recently, we have operated on 13 ears of 11 patients (two bilateral patients), aged from 5 to 21, 10 atresia, 2 stenosis, and one post-operative sequelae. Two dimensional target computed tomography was useful for surgical approach. We drilled the temporal bone at the external auditory meatus with the one tunnel method upto sufficient width for making the tympanic cavity and the external auditory canal.
Meatotympanoplasty for congenital auditory canal atresia or stenosis is good news for the patients suffering from this disease.
