目的探讨下颌前移矫治器治疗中重度OSAHS的疗效。方法选取20例中重度OSAHS患者,男19例,女1例,平均年龄54±12岁,采用下颌前移矫治器治疗,观察时间半年,分别做治疗前后上气道测量、多导睡眠监测及Epworth评估。对治疗前后结果进行统计学处理。结果戴用下颌前移矫治器后头颅侧位片显示H-MP由19.2±5.17mm降为15.25±6.20mm,P<0.05,H-C3由39.40±4.18mm增加为41.80±4.30mm,P<0.05;UPW-PNS、SPP-SPPW、Mc1-Mc2、U-MPW及PAS均增加,P<0.05;多导睡眠监测显示呼吸暂停指数(AI)、低通气、呼吸紊乱指数(AHI)、呼吸性醒觉指数(RAI)、呼吸暂停平均时间MAT及呼吸暂停最长时间LAT;都降低,P<0.05;血氧饱和度及睡眠效率显著增加,P<0.05;Epworth测量表示治疗前平均16±5分。治疗后7±4分,P<0.05。结论下颌前移矫治器能够有效治疗中重度OSAHS患者。
Objective To investigate the curative effect of mandibular advancement on moderate-severe OSAHS. Methods Twenty patients with moderate to severe OSAHS were selected, including 19 males and 1 females, with an average age of 54 ± 12 years. The patients were treated with mandibular advancement appliance. The observation time was six months. Epworth Assessment. The results before and after treatment were statistically analyzed. Results After the mandibular advancement appliance was used, the H-MP decreased from 19.2 ± 5.17mm to 15.25 ± 6.20mm, P <0.05, and the H-C3 increased from 39.40 ± 4.18mm to 41.80 ± 4.30mm, P < P <0.05). The levels of UPW-PNS, SPP-SPPW, Mc1-Mc2, U-MPW and PAS increased, P <0.05; polysomnography showed apnea, hypopnea, P <0.05; The oxygen saturation and sleep efficiency increased significantly, P <0.05; Epworth measurement showed that the average before treatment 16 ± 5 Minute. 7 ± 4 points after treatment, P <0.05. Conclusion Mandibular advancement appliance can effectively treat patients with moderate-severe OSAHS.
