摘要
用夜间多导睡眠图监测结合X线头影测量法,分析了口腔矫治器对10例阻塞性睡眠呼吸暂停综合征患者气道、睡眠结构及呼吸功能的影响。结果显示,戴用矫治器后下颌在水平向和垂直向的位移平均分别为1.73mm和9.30mm,上后气道间隙平均增加2.80mm(P<0.01),中气道间隙平均增加6.75mm(P=0.01),下气道间隙变化的差异无显著性(P>0.05)。10名患者的呼吸暂停指数平均下降15.98次/小时(P<0.01),有9名患者总呼吸紊乱指数平均下降32.81次/小时(P<0.01),另一例无低通气记录。最低SaO2平均从73.87%上升到85.50%(P<0.01)。上气道阻塞频率的降低,可归因于矫治器对口咽部结构的影响。作者认为,口腔矫治器是治疗该病的一种有效疗法。
