Reconstruction of Chin Defects Using an O to Z Bilateral Rotation Flap

引用

Journal of Cosmetics, Dermatological Sciences and Applications 2012年第2期2卷 41-44页

作者： sasha jenkins Katarina G. Lequeux-Nalovic Department of Dermatology Emory University Atlanta USA

Reconstruction of defects on the chin represents a challenge given the functional, multidirectional movement of the chin subunit. In this article, we describe the surgical technique of a bilateral O to Z rotation flap on the chin, as well as complications, cosmetic outcome, and patient satisfaction. A retrospective chart review from January 2009-June 2011 identified twelve patients where an O to Z flap was used to repair a surgical defect. Of the twelve patients identified, one patient had a presumed post-operative infection, and one patient required additional corrections. There were no complications of hematomas or flap necrosis. Overall patient cosmetic outcome was excellent. An O to Z closure is an option for chin reconstruction of small to medium defects that offers a satisfactory cosmetic outcome, high patient satisfaction and low complication rate.
