title: The Retrograde Transposition of the Remnant Earlobe in Patients With Low-Set Microtia.
abstract: During auricle reconstruction, lobular transposition has become a routine technique applied by most of surgeons. But to some low-set remnant ears, it is difficult to manipulate the conventional lobule transposition method in clinical application. In this article, the authors introduce a method to retrogradely transpose the remnant ear with the the ratio of length:width of the lobular flap being 4-5:1. The lobule transposition could be applied during the first stage of Nagata method or the third stage using expansion method. The authors take the superior part of the remnant ear as the pedicle and make the incision at the middle and inferior parts of the remnant ear to form the lobular flap. Then the inferior lobule is rotated posteriorly and superiorly to cover the rear end of the framework and to form the inferior part of helical rim. The results of the reconstructed auricles are satisfactory with aesthetic natural earlobes and the location of the reconstructed ear is symmetric to the contralateral ear. The authors believe that to the 2% to 5% patients with low-set microtia, this is a good way to make use of remnant ear for the purpose of a real earlobe.
