In reconstructing anterior defects of the ear, postauricular flaps represent a popular option. The pedicle of such transauricular flaps can be superior, inferior, medial, or lateral. The postauricular helix-based adipodermal-pedicle turnover (PHAT) flap is an original single-stage transauricular technique for defects of the antihelix and scapha. Its skin paddle is on the posterior aspect of the ear. Its lateral de-epithelialized pedicle in front of the helix allows for it to easily reach peripheral anterior defects. In cases in which the underlying cartilage is involved, the extended PHAT (ePHAT) flap allows for restoring the contours of the ear without a cartilage graft.
Between 2009 and 2011, a PHAT flap was used in 5 cases of defects of the antihelix or the scapha after tumor resection, 3 of which are in an extended version (ePHAT flap).
There were no complications and a satisfactory aesthetic result was achieved in all cases.
The PHAT flap is an original single-stage procedure for anterior auricular defects located on the antihelix or scapha. The single-layer PHAT flap is indicated in purely skin defect. The triple-layer ePHAT flap includes two subcutaneous extensions which increase its thickness and is indicated to restore the ear contours when cartilage has been removed.
在重建耳部前侧缺损时，耳后皮瓣是一种常用的选择。此类经耳皮瓣的蒂部可以位于上方、下方、内侧或外侧。基于耳后螺旋的脂肪真皮蒂翻转（PHAT）皮瓣是一种用于重建对耳轮和耳舟缺损的原创单阶段经耳技术。其皮瓣位于耳的后侧。其在螺旋前方的外侧去上皮蒂使其能够轻松到达周边前侧缺损部位。在涉及下方软骨的情况下，扩展PHAT（ePHAT）皮瓣无需软骨移植即可恢复耳部轮廓。
2009年至2011年间，5例肿瘤切除后对耳轮或耳舟缺损患者使用了PHAT皮瓣，其中3例采用扩展版（ePHAT皮瓣）。
所有病例均无并发症，美学效果令人满意。
PHAT皮瓣是用于对耳轮或耳舟部位耳部前侧缺损的原创单阶段手术方法。单层PHAT皮瓣适用于单纯皮肤缺损。三层ePHAT皮瓣包括两个皮下延伸部分，增加了其厚度，适用于在软骨已被切除时恢复耳部轮廓。
