Sumario:BACKGROUND: Reconstruction of Grade III microtia is a challenging entity in maxillofacial esthetic rehabilitation. Several advocacies and philosophies exist in this field. The aim of the manuscript is to present a single South Indian Experience with Ear reconstruction among South Indian Population. MATERIALS AND METHODS: Retrospective analysis of unilateral Grade III microtia reconstruction was performed. Using a set of predefined inclusion and exclusion criteria, the population was selected. Outcome measures in terms of the ear size, auriculocephalic angle, and the conchal depth were measured in the reconstructed and normal side. Descriptive statistics is presented. RESULTS: Twenty-four patients formed the study group and had undergone the classical two-stage reconstruction in a similar fashion. The mean ear size in normal side was 65.8 ± 2.8 mm whereas on the reconstructed side, it was 61.3 ± 5.8 mm. The center's technique achieved above 75% similarity as that of the other normal ear. The mean auriculocephalic angle was 44.6 ± 5.2° whereas for the surgically reconstructed ear, it was 41.9 ± 2.6°. Overall, in these patients, we achieved a 79.94% similarity of auriculocephalic angle in the reconstructed ear as compared to the normal auricle. The conchal depth was 19.2 ± 2.1 mm and 16.6 ± 1.9 mm for normal and reconstructed ear, respectively. In terms of conchal depth, the present study group showed an achievement of 82.88% of accuracy even after a prolonged follow-up. DISCUSSION AND CONCLUSION: The center employs a classic two stage reconstruction with a customized prosthesis that helps to avoid the loss of projection geometry and minimizes adhesion, infection, and early loss of structural stability.
