摘要/Abstract

摘要： 目的:探讨OSAHS患者戴用下颌前移矫治器对咀嚼肌肌电活性的初期影响。方法:随机选取37例使用下颌前移矫治器治疗的OSAHS患者,分别在戴用前和戴用1周后利用Bio-EMGⅢ肌电图仪记录在息止位、最大紧咬位时颞肌前束、咬肌的表面肌电图,对比分析左、右侧同名肌肉的不对称指数,以及颞肌前束/咬肌的活动指数在戴用前后的变化。结果:戴用下颌前移矫治器后在息止位和最大紧咬位:1)各组肌肉肌电幅值均未见明显变化;2)各咀嚼肌的不对称指数均未见明显变化;3)颞肌前束/咬肌的活动指数明显增加(P<0.05)。结论:OSAHS患者戴用下颌前移矫治器1周后出现了颞肌前束相对咬肌肌电活动强度增加的变化,应对其进行长期随访。

Abstract: Objective: To investigate the electromyography of masticatory muscles in OSAHS patients with short-term treatment with the MAD. Methods: 37 patients with OSAHS who had been treated with the MAD were included in the study group. The Bio-EMGⅢ was conducted to identify the surface electromyography (EMG) of temporal anterior (TA) and masseter muscle (MM) changes at rest position and clenching. The asymmetry index of bilateral muscles and the activity indexes of TA/MM were compared before and after 1 week treatment. Results: 1)No obvious changes of the activity of masticatory muscles at rest position and clenching were found 1 week after MAD treatment; 2)No obvious changes of the asymmetry index of masticatory muscles happened; 3) The activity indexes of TA/MM significantly increased (P<0.05). Conclusion: The coordinated EMG activity of different masticatory muscles was changed by using the MAD over a short period of time.
