Reconstruction of Microtias with Constricted Ear Features: A 22-Year Experience

Background: The surgical correction of 'microtias with constricted ear features' has remained a challenge due to the variable shape and large volume of the remnant cartilage and skin involved. In order to clarify how this remnant cartilage and skin should be treated, we have reviewed and analyzed cases operated at our Center. Methods: A total of 167 cases of Microtia with Constricted Ear Features, operated from 1992 to 2014, were included in the study. They were reviewed through medical records and photographs, analysis of surgical methods, and postoperative outcomes. Results: A total of 141 cases (84 percent) were followed for 2 months to 13 years (an average of 28 months). The average score given to the aesthetic outcomes, rated on a four-point Likert scale (i.e., 1=poor, 2=fair, 3=good, 4=excellent), was 3.1. For framework construction, we used remnant cartilage saving methods (n=37) or remnant cartilage replacement methods (n=104). The average (median) scores for the aesthetic outcome for these methods were 2.56 (3) and 3.36 (4), respectively. The difference in these scores was statistically significant (P
