Anthropometric Difference of Unilateral Microtia Reconstructed Auricle.

ObjectivesThis study aimed to evaluate the surgical outcomes of auricular reconstruction by comparing the anthropometric differences between the reconstructed and normal auricles.DesignCross-sectional study.SettingAll microtia patients who underwent surgery at Airlangga University Hospital, Indonesia.Patients, Participants:Patients with unilateral microtia who had completed auricular reconstruction using autologous costal cartilage at Airlangga University Hospital, with a more than 3 months follow-up between 2019 and 2022.InterventionsPrimary data were obtained through auricle photographs, and a medical engineer performed anthropometric measurements. The data were analyzed using a paired t test.Main Outcome MeasuresThe primary parameters measured were the ratios of auricle width to lobular width and auricle height to lobular height for each subject's right and left auricles. The differences between the reconstructed auricle and the normal contralateral side were assessed.ResultsIn a sample of 20 patients, no significant difference was observed in the ratio of auricle width to lobular width (P > .05). However, a significant difference was found in the ratio of auricle height to lobular height between the reconstructed auricle and the normal contralateral side (P < .05).ConclusionsFuture studies should consider utilizing the ratio of auricle width to lobular width as an objective indicator of success in microtia reconstruction.
