The aim of this study was to investigate and elucidate the anatomical basis for the use of the inferiorly based masseter muscle flap in the reconstruction of oropharyngeal defects after ablative surgery. The anatomy of the masseter muscle, with particular emphasis on its blood supply, was studied using plain and coloured resin injected dissections and a series of digital subtraction angiograms and external carotid arteriograms. Both techniques were demonstrated to be reliable and effective means of anatomical investigation of blood vessels. The vascular anatomy of the masseter muscle and the anatomical and angiological results as well as a case report are described. The masseter muscle, when used as an inferiorly based flap, provides the necessary bulk for reconstruction of moderate size defects in the lateral border of the tongue, posterior floor of the mouth, retromolar trigone, anterior tonsillar pillars and lateral pharyngeal wall. Although the masseter muscle has small dimensions, it offers a reliable method of reconstruction in selected defects without the disadvantages of cosmetic and functional loss.
本研究的目的是探讨并阐明在消融性手术后使用以咬肌下份为蒂的肌皮瓣修复口咽缺损的解剖学基础。通过普通和彩色树脂注入解剖以及一系列数字减影血管造影和颈外动脉造影，对咬肌的解剖结构，尤其是其血供进行了研究。这两种技术均被证明是可靠且有效的血管解剖学研究方法。本文描述了咬肌的血管解剖结构、解剖学和血管学研究结果以及一例病例报告。当将咬肌用作以其下份为蒂的肌皮瓣时，可为修复舌外侧缘、口底后部、磨牙后三角、扁桃体前柱和咽侧壁中等大小的缺损提供必要的组织量。尽管咬肌尺寸较小，但对于特定缺损，它提供了一种可靠的修复方法，且不存在美观和功能丧失的缺点。
