International trends in the treatment of microtia

Background: Microtia is a well-known craniofacial malformation treatable with numerous different treatment strategies and techniques. The purpose of this study was to analyze the current international trends in microtia repair. Methods: All surgeons attending the fourth International Ear Reconstruction Congress in Edinburgh received a questionnaire by e-mail about their current surgical practice in microtia care. Results: Thirty-one questionnaires were received. Most primary reconstructions are performed at ages 8 to 10 years using autologous cartilage from the ipsilateral sixth to eighth ribs. Most surgeons make a multilayer framework, leaving a subcutaneous pedicle. Suction drainage was used in all patients. On average, the second stage was performed more than 6 months later using a mastoid flap. Most surgeons do not reconstruct the middle ear. Conclusions: Microtia reconstruction is performed in many different ways, with numerous treatment and postoperative possibilities. © 2011 by Mutaz B. Habal, MD
