The anterolateral thigh free flap is one of the most commonly used flaps in reconstructive procedures. The purpose of this study was to assess this new classification of chimeric anterolateral thigh free flaps.
Sixty-five patients underwent free anterolateral thigh chimeric free flap reconstruction of defects in the head and neck region. We summarized the anatomic features of perforators, including the number and origin of the perforators.
Sixty-five cases of femoral anterolateral double island flaps were divided into 3 types: trunk type (type I), 11 cases (16.9%), in which the perforators of two flaps originated in the descending branch and the transverse branch of the lateral femoral circumflex artery; branch type (type II), 45 cases (69.3%), in which both the perforators originated in the descending branch or the transverse branch of the lateral femoral circumflex artery; and bifurcation type (type III), 9 cases (13.8%), in which two perforators originated in the bifurcation of one perforator that originated in the descending branch or the transverse branch of the lateral femoral circumflex artery. All 65 flaps survived and none showed partial necrosis.
The anterolateral thigh chimeric flap can be divided into 3 types: trunk type (I type), branch type (II type) and bifurcation type (III type).
股前外侧皮瓣是重建手术中最常用的皮瓣之一。本研究旨在评估这种新的股前外侧皮瓣嵌合分类方法。
65 例头颈部缺损患者接受游离股前外侧嵌合皮瓣重建。我们总结了穿支的解剖学特征，包括穿支的数量和起源。
65 例股前外侧双岛皮瓣分为 3 型：干型（Ⅰ型）11 例（16.9%），2 个皮瓣的穿支均发自旋股外侧动脉降支和横支；支型（Ⅱ型）45 例（69.3%），均发自旋股外侧动脉降支或横支；分叉型（Ⅲ型）9 例（13.8%），2 个穿支均发自旋股外侧动脉降支或横支发出的一支穿支的分叉处。65 个皮瓣全部存活，无部分坏死。
股前外侧嵌合皮瓣可分为 3 型：干型（Ⅰ型）、支型（Ⅱ型）和分叉型（Ⅲ型）。
