Abstract：Objective To investigate the methods of auricle reconstruction for microtia. Methods Cases treated be-tween January 2003 and December 2012 were reviewed. Local skin was expanded and the autologous rib cartilaginous skele-ton was shaped based on the digital images of auricle frames generated with the Photoshop software using photos of the con-tralateral normal auricle. The skeleton was then wrapped in expanded local skin flap to complete reconstruction. Results Pa-tients (1,165 ears) were followed-up for six months to ten years. Cartilage frame absorption and distortion of various degrees were seen in 56 patients (56 ears)and infection in 2 patients with liquefaction and necrosis of the cartilage framework. The reconstructed ear showed good match to the contralateral ear in 1,044 cases (1,107ears), with clear structural features, com-parable contours and symmetrical skull-ear angle. Conclusions In addition to adequate local skin expansion, the use of dig-ital design technology in guiding preparation of autologous rib cartilage skeleton improves auricle reconstruction outcomes with few complication, It helps improve therapy for microtia.
