肌电图是分析口腔器官肌肉成分的重要手段。对咀嚼肌肉进行了大量的肌电图研究；'-'然而，颊肌被认为是口腔结构的一个组成部分，并被一些人'2-14认为有助于咀嚼，却很少受到关注。触诊、肌肉附着观察和麻痹研究先前已表明颊肌在以下表现时处于活跃状态：(1) 压缩脸颊，从而帮助咀嚼'2-'4 和吹气；'2"3 (2) 横向拉动嘴角；12,13 (3) 将嘴唇拉向牙齿；'2 和 (4) 帮助吞咽。'3 对这块肌肉进行的少数肌电图研究与孤立的现象有关，例如帮助吞咽义齿的固位和稳定性，15 在吮吸拇指和手指吮吸患者中的作用，6 以及对牙齿缺失和义齿治疗的反应。7 本研究旨在确定颊肌在正常受试者咀嚼、吞咽、吹气和吸吮等活动中的作用。
Electromyography is a valuable means of analyzing the muscular components of the oral apparatus. Numerous electromyographic studies have been made of the muscles of mastication;'-' yet, the buccinator muscle, recognized as an integral part of the oral structure and considered by some'2-14 to aid mastication, has received little attention. Palpation, observation of muscle attachments, and paralysis studies have previously shown the buccinator muscles to be active during the following performances: (1) compressing the cheek, thereby aiding mastication'2-'4 and blowing;'2"3 (2) drawing corner of mouth laterally; 12,13 (3) pulling lips against teeth;'2 and (4) aiding in swallowing.'3 The few electromyographic studies made of this muscle have been related to isolated phenomena, such as aid to denture retention and stabilization,15 role in thumb-sucking and finger-sucking patients,'6 and response to loss of teeth and denture treatment.'7 The present study was designed to determine the role of the buccinator muscle in such activities as chewing, swallowing, blowing, and sucking in the normal subject.
