Joint expansion of double fascia flaps for full-ear mastoid reconstruction

Abstract

Objective To study the methods and clinical effects of joint expansion of double fascia flaps wrapping the Medpor to perform full-ear reconstruction on congenital microtia deformity. Methods 60 patients with congenital microtia deformity were selected. including 22 left ears and 38 right ears. Majority had loss of ear auricle or only partial earlobe. Phase Ⅰprocedures included: temporal-parietal branch was used for the vascular pedicle, and mastoid area behind the ear was moved and expanded for fascia flap. Phase Ⅱ included: the joint expansion of double fascia flap wrapped Medpor to do full-ear reconstruction. Results Flaps survived and no complications for all 60 patients. Reconstructed ears had lifelike appearance and clear anatomical structures. Auriculocephalic angulars positions and sizes were consistent with the healthy ears. None of them had exposed prosthesis and scar contraction. Three-dimensional shapes were good. Conclusions Joint expansion of double fascia flap wrapping Medpor could avoid the chest wall deformity and exposed prosthesis. The fine structure of the reconstructed ear is satisfactory.
