선천성 외이도 폐쇄증의 임상

Background and Objectives: Congenital aural atresia is very serious disease because its morphologic and functional deficit can affect the life of the child and parents significantly. Morphologic and audiologic restoration through surgical correction is mandatory to otologist. We analysed our experiences in surgical treatment of congenital aural atresia for the purpose of better understanding of this disease. Subjects and Methods: Present study analysed thirty three cases (34 ears) of canaloplasty patient for six years. The pre- and post-operative clinical findings and audiologic results were collected from retrospective chart reviews. Results: The most common ossicular anomaly was malleus-incus fusion (38.2%). There was no significant relationship between the degree of auricular malformation and degree of ossicular anomaly. The patient with hearing gain more than 20 dB of airconduction was twelve out of 23 (52.2%). Postoperative complication occured 23.5% (8/34) of cases and half of them were canal stenosis. Conclusions: For prevention of postoperative stenosis and to get a better hearing results, we should make the external canal more widely. A meticulous management of canal skin and graft is mandatory.
