The use of the motor nerve to masseter has proved to be a reliable and sensible solution in facial reanimation as a donor for free muscle transfer. In this paper we describe the topographic anatomy of the nerve to masseter and our original technique for its quick and safe harvesting.
This anatomical study is based on the dissection of the nerve to masseter in 17 embalmed cadaverous sites and is focused on the anatomical relations between the nerve and the surrounding structures. Also buccal and zygomatic branches of the facial nerve were dissected and assessed and the resulting data are compared.
The nerve to masseter has a predictable track inside the muscle which can be identified topographically within a square area under the zygomatic arch. This area is different between males and females and its accuracy has been tested on six patients at the Canniesburn Unit.
The nerve to masseter emerges in a very predictable point from the mandibular notch - immediately below the zygomatic arch - to run within the muscle belly. The approach here described allows safer and faster harvesting of the nerve to masseter with minimal dissection through the muscle.
在面部神经再支配中，使用咬肌运动神经作为游离肌肉移植的供体已被证明是一种可靠和合理的方法。本文介绍了咬肌神经的局部解剖学结构，并详细描述了我们在咬肌神经快速、安全获取方面的原创技术。
本解剖学研究基于对 17 个防腐尸体标本的咬肌神经解剖，重点关注神经与周围结构之间的解剖关系。同时还解剖和评估了面神经的颊支和颧支，并对所得数据进行了比较。
咬肌神经在肌肉内有一条可预测的轨迹，可以在颧弓下方的一个正方形区域内进行定位。这个区域在男性和女性之间存在差异，我们已经在 Canniesburn 医院的 6 名患者中对其准确性进行了测试。
咬肌神经从下颌切迹以非常可预测的方式穿出——就在颧弓下方——然后在肌肉内部运行。本文描述的方法允许更安全、更快地获取咬肌神经，同时通过肌肉进行最小的解剖。
