Snoreguard矫治器治疗阻塞性呼吸暂停综合征疗效分析

目的 :探讨 Snoreguard矫治器对阻塞性呼吸暂停综合征 ( OSAS)患者气道、睡眠结构的影响。方法 :选择 2 6岁～ 5 9岁患有 OSAS的患者 8例 ,在睡眠时分别配戴 Snoreguard矫治器 ,同时结合应用头颅侧位片、夜间多导睡眠图监测来测定分析配戴 Snoreguard矫治器的测量指标 ,进行统计分析。结果 :配戴 Snoreguard矫治器后 ,8例患者的AI值、平均呼吸暂停时间、AHI值均有显著性的降低 ( P<0 .0 1) ,Sa O2 显著增加 ( P<0 .0 1) ,HI值降低显著 ( P<0 .0 5 )。鼾声指数大幅度减轻甚至消失 ( P<0 .0 1)。配戴矫治器后下颌在水平向和垂直向的位移平均为 2 .0 3 mm和 8.74m m,IAS无显著变化 ,MAS变化明显 ( P<0 .0 5 ) ,最显著性改变的是上气道后间隙 ( SPAS) ( P<0 .0 1) ,SPL 减少 3 .64m m。结论 :Snoreguard矫治器是通过将下颌限制在一个前伸位 ,从而改变口咽部的结构影响上气道大小来达到治疗效果

The study on the effect of Snoregurad appliance on OSAS

Objective:The purpose of the present study was evaluate the effctiveness of Snoreguard appliance on OSAS by combining the use of overnight polysomnography and cephalometry.Methods:8 OSAS patients(male 6,female 2),aged from 26 to 59 years.Those patients wore the Snoreguard appliance when sleeping in night.The association between the improvement of respiratory variables and the cephalometric variables were investigated on the basis of linear correlation anasis.Results:There was significant decreased in the average.The Average Apnea Index,Respiratory Disturbance Index( P <0.01),the lowest SaO 2 value increased( P <0.01),horizontal and vertical mean changes in mandibular postion while the appliance was worn were 2.03 mm and 8.75 mm.The most significant increased( P <0.01) was the superior airway space,while the mean middle airway space increased.The inferior airway space didn′t change significantly.SPL was decreased by 3.64 mm.Conclusion:The reduction in the rate of airway obsructive events is attributed to the effect of appliance on the orophargneal structures.
