口腔矫正器治疗阻塞性睡眠呼吸暂停综合征的临床观察

Clinical observation of oral appliances in the treatment of obstructive sleep apnea syndrome

目的探讨口腔矫正器对３６例阻塞性睡眠呼吸暂停综合征（ＯＳＡＳ）患者的临床疗效。方法制作“下颌前移型”矫正器让３６例ＯＳＡＳ患者在睡眠时配戴，用多导睡眠图监测患者治疗前后呼吸紊乱指数（ＡＨＩ）、夜间最低血氧饱和度（最低ＳａＯ２）与最长呼吸暂停时间（Ｔ），用ｔ检验进行统计学比较。结果使用口腔矫正器后患者的ＡＨＩ明显降低（Ｐ＜００５），最低ＳａＯ２亦有明显改善（Ｐ＜００５），Ｔ明显缩短（Ｐ＜００５）。结论口腔矫正器能使上气道增宽，使下颌稳定于一个前伸位置，舌和软腭前移，增加睡眠时的有效通气量，改善睡眠质量，是治疗ＯＳＡＳ的一个有效的辅助手段。

Objective To explore the effect of treatment with the oral appliances on 36 cases with obstructive sleep apnea syndrome (OSAS). Methods The patients are requested to put on the proper oral appliances when sleeping. Polysomnography (PSG)are used to measure the apnea hypoventilation index(AHI),lowest SaO2 and longest apnea time before and after treatment. Results Having been Compared with the obtained data, the AHI decreased, the lowest SaO2 increased and the longest apnea duration shortened significantly (P<005) in OSAS patients after oral appliance treatment. Conclusions The oral appliances helped to widen the upper airway, stabilized the lower jaw bone on a forward position to make the tongue and the soft palate move forward, increased the effective amount of inhaled air while sleeping and improved sleeping quality. There fore,it is an effective method for the treatment of OSAS.
