Sulcus construction in microtia repair: a retrospective comparison of different techniques.

OBJECTIVE To compare the auricular projection results across 3 different techniques of sulcus construction in microtia repair (using a temporoparietal fascial flap, a retroauricular fascial flap from the mastoid region, or a superficial muscular aponeurotic system advancement flap). METHODS All the patients had been photographed at least 3 months after the second stage (construction of the retroauricular sulcus) in auricular reconstruction for microtia. The auricular projection of each patient was measured, and the results of 3 different techniques were compared. RESULTS No statistically significant differences in the auricular projection results were observed among patients operated on using the 3 techniques. CONCLUSIONS The superficial muscular aponeurotic system advancement flap is suitable for patients requiring middle ear and auricle reconstruction. The performance of this flap is easier, quicker, less expensive, and associated with fewer perioperative complications compared with the other 2 techniques described herein.
