Congenital Microtia Treated at Sapporo Medical University Hospital: Clinical Characteristics and Associated Anomalies.
Seventy-three children who underwent plastic surgery for their external ear malformations between December 2010 and May 2013 at the Sapporo Medical University Hospital were evaluated. The predominance of right-sided malformation (62%) in males (71%) was similar to that reported previously, but the number of bilateral cases (9.3%) was lower than that in previous reports. We classified patients' ears using Marx's classification. The pure-tone average (average air conduction thresholds measured at 500, 1,000 and 2,000 Hz) was used as the representative value for the hearing level, which was compared with a patient's Marx classification. We evaluated the facial nerve position using high-resolution computed tomography scans. A thorough understanding of anatomical variations and complications, as well as performing appropriate treatments, is required for otolaryngologists to effectively manage congenital microtia.
