BACKGROUND: Due to its complex, three-dimensional morphology, auricular reconstruction remains one of the most challenging procedures in reconstructive surgery. A subject that remains controversial, however, is the question of the growth potential of the cartilaginous framework. This study explored the anthropometric changes of the reconstructed auricle and the contralateral normal ear in a series of Asian patients. METHODS: The records of 126 unilateral microtia patients in three age groups who underwent autogenous costal cartilage auricular reconstruction between 2007 and 2010 were reviewed. The average age was 14 years, and the average follow-up was 2.5 years. The auricular height was measured as the distance from the supra-auricle to the subauricle, and the width was measured as the distance from preauricle to the postauricle. Measurements of the height and width of the reconstructed auricle and the contralateral normal side were taken at implantation and at the final follow-up. Comparisons between the three age groups were performed using a paired Student t test to examine the mean auricular heights and widths for significant interval changes in size. RESULTS: The measurements showed average width increases of 1.24 mm (3.68%) and 1.35 mm (3.91%) in the reconstructed auricles of children and adolescents, respectively, but we did not find obvious changes in the adult group. No significant differences were found in the height measurement of the reconstructed auricle in the ...
