The retroauricular skin flap is a useful technique to provide skin coverage for full-thickness ear defects resulting from trauma or oncological resection. Defects that involve the posteromedial and retroauricular skin, however, limit the use of this flap. An extended retroauricular flap used to reconstruct a middle-third marginal defect extending anteriorly into the concha and posteriorly onto the retroauricular skin is described. Triangular extensions of retroauricular skin adjacent to the distal aspect of the flap as well as flap elevation posteriorly into the scalp were used to increase flap length. This technique provided acceptable aesthetic results with minimal distortion of ear shape and contour.
耳后皮瓣是一种为创伤或肿瘤切除导致的全层耳部缺损提供皮肤覆盖的有用技术。然而，涉及耳后内侧和耳后皮肤的缺损限制了该皮瓣的应用。本文描述了一种用于修复延伸至耳甲前部并向后延伸至耳后皮肤的中耳部边缘缺损的扩展耳后皮瓣。使用皮瓣远端附近的耳后皮肤三角形延伸以及皮瓣向后提升至头皮来增加皮瓣长度。该技术提供了可接受的美学效果，耳部形状和轮廓的变形最小。
