摘要
目的 明确颏舌肌 (genioglossus,GG)在口腔矫治器治疗阻塞性睡眠呼吸暂停综合征(obstructivesleepapneasyndroms ,OSAS)中的作用。方法 采用多导夜间睡眠监测和同步GG肌电图检查的方法 ,对 15例男性OSAS患者阻鼾器治疗前后的GG肌电活性进行比较。结果 治疗后患者整夜和睡眠呼吸暂停发作时的GG肌电活性均降低 ,GG肌电活性的波动幅度也得到了改善。结论口腔矫治器治疗OSAS的机理是机械性扩大上气道。
Objective The effect of snoreguard on the genioglossus (GG) muscle activity of OSAS patients was investigated Methods Fifteen male patients with mild to severe OSAS were diagnosed by overnight polysomnographic and GG EMG studies, and reexamined with snoreguard GG muscle activities of these patients with and without snoreguard were compared Results The results revealed that the overnight GG muscle activity decreased significantly and the fluctuating GG muscle activity was improved effectively by the treatment of snoreguard Conclusion The treatment mechanisms of mandibular advancing appliance on OSAS are mechanical enlargement of upper airway and the passivity of GG muscle during treatment
