Microtia and congenital aural atresia

The purpose of this study was to show the clinical characteristics of microtia and congenital aural atresia cases in Turkey and to make the classification. For this purpose, records of 28 patients with microtia who were admitted to the ENT Clinic of Eskisehir Military Hospital, Turkey, between 1995 and 2011 and 3 patients admitted to the ENT outpatient clinic of Kocaeli Derince Education and Research Hospital, Turkey, were analyzed retrospectively. Of the total 31 patients with microtia (35 microtic ears), involvement of the right ear of 20 patients (64.5%), the left ear of 7 patients (22.5%), and bilateral involvement in 4 patients (12.9%) were observed. There was a unilateral involvement in 27 patients (87.1%). According to the Marx grading, 2 patients (5.7%) had grade 1 malformation, 3 (8.6%) had grade 2 malformation, 29 (82.9%) had grade 3 malformation, and 1 (2.9%) had grade 4 malformation (anotia). Although the characteristics of microtia vary in different population, the results in Turkey are consistent with those in the literature.
