背景：基于面动脉大分支的颏下皮瓣是头颈部重建术中最常用的皮瓣选择。本报告的目的是阐明颏下皮瓣的解剖学方面，以提高该皮瓣的效用。方法：对10具尸体注射改性氧化铅-明胶混合物。选择四具尸体进行三维重建，使用螺旋计算机断层扫描仪和专门的体绘制软件。对每一层进行解剖、血管造影和摄影，勾勒出颈部每个穿支的路线。计算每个源血管所提供的血管区域的面积。使用Scion Image软件测量表面面积。结果：面部动脉、甲状腺上动脉、颏动脉、舌动脉、颏下动脉这几条动脉穿支滋养了前颈、下颌骨的皮肤和肌肉。颏下动脉起源于面动脉的直径为1.7±0.4 mm。在它通向下巴的过程中，它向皮肤输送1.8±0.6个穿支。所提供领土的平均面积为45±10.2厘米(2)。它最大的穿支起源于二腹肌前腹内侧边界的后面。颏下动脉、面动脉和舌下动脉的穿支之间有多处吻合。结论：本研究阐明了颏下皮瓣的解剖结构，并对这一重要的头颈部供体部位提供了三维的认识。(C) 2010年英国整形、重建和美容外科医师协会。Elsevier Ltd.出版。版权所有。
Background: The submental flap, based on a large branch of the facial artery, is an excellent flap option which is most commonly used for head and neck reconstruction. The purpose of this report is to clarify aspects of the anatomy of the submental flap in order to improve the utility of this flap.Methods: Ten cadavers were injected with a modified lead oxide-gelatin mixture. Four cadavers were selected for three-dimensional reconstruction using a spiral computed tomography scanner and specialised volume-rendering software. Dissection, angiography and photography of each layer were performed to outline the course of every perforator in the neck. The area of the vascular territory supplied by each source vessel was calculated. Surface areas were measured using Scion Image software.Results: The skin and muscles on the anterior neck and mandible are nourished by several arterial perforators: facial artery, superior thyroid artery, mental artery, lingual artery and the submental artery. The diameter of the submental artery was 1.7 +/- 0.4 mm at its origin from the facial artery. It sends 1.8 +/- 0.6 perforators to the skin on its course towards the chin. The average size of the territory supplied was 45 +/- 10.2 cm(2). Its largest perforating branch arises from behind the medial border of the anterior belly of the digastric muscle. There were multiple anastomoses between perforators from the submental artery, facial artery and sublingual artery.Conclusions: This study clarifies the anatomy of the submental flap and provides a three-dimensional understanding to this important head and neck donor site.
