[Ear reconstruction for microtia with craniofacial deformities].

Abstract

OBJECTIVE To investigate the methods and effectiveness of ear reconstruction for the microtia patients with craniofacial deformities. METHODS Between July 2000 and July 2010, ear reconstruction was performed with tissue expander and autogenous costal cartilages in 1 300 microtia patients with degree II+ hemifacial microsoma, and the clinical data were reviewed and analyzed. There were 722 males and 578 females, aged 5 years and 8 months to 33 years and 5 months (median, 12 years and 2 months). The expander was implanted into the retroauricular region in stage I; ear reconstruction was performed after 3-4 weeks of expansion in stage II; and reconstructed ear reshaping was carried out at 6 months to 1 year after stage II in 1 198 patients. RESULTS Of 1 300 patients, delayed healing occurred in 28 cases after stage II, healing by first intention was obtained in the other 1 272 cases, whose new ears had good position and appearance at 1 month after stage II. After operation, 200 cases were followed up 1-9 years (mean, 3 years). One case had helix loss because of trauma, and 1 case had the new ear loss because of fistula infection. At last follow-up, the effectiveness were excellent in 110 cases, good in 65 cases, and fair in 23 cases with an excellent and good rate of 88.4%. CONCLUSION It is difficulty in ear reconstruction that the reconstructed ear is symmetrical to the contralateral one in the microtia patients with degree II+ hemifacial microsoma. The key includes the location of new ear, the fabrication of framework, and the utilization of remnant ear.
