目的 :观察一种下颌前移性口矫器治疗阻塞性睡眠呼吸暂停 (OSA )的疗效并探讨其治疗原理 ,探讨应用颌面结构分析法来预测口矫器的疗效。 方法 :70例经多导睡眠仪 (PSG)检查确诊的 OSA患者 ,男性 6 3例 ,女性 7例 ,平均年龄 :(5 0 .5± 11.6 )岁 ,呼吸暂停指数 (AI) (34 .9± 2 1.3)次 /h,夜间最低血氧饱和度 (6 6 .3± 16 .5 ) %。经口腔科会诊后制作口矫器 ,治疗 3个月后复查 PSG检查。每例患者治疗前均在带及不带口矫器两种状态下摄头颅侧位片作颌面结构分析。 结果 :治疗后 AI由 (34 .9± 2 1.3)次 /h减至 (15 .6± 19.2 )次 /h(P<0 .0 0 0 1) ,夜间最低血氧饱和度由 (6 6 .3± 16 .6 ) %升至 (74.1± 15 .5 ) % (P<0 .0 0 1)。共有 45例患者 AI减少≥ 5 0 %。反应良好组患者缩颌较明显 ,前上面部长度较长 ,置入口矫器后下颌显著前突、上气道径增宽、长度缩短、上气道面积增大。 结论 :口矫器对部分 OSA患者具有确切疗效 ,其治疗作用可能主要与改善睡眠期上气道周围结构关系 ,保持气道通畅有关。
OBJECTIVE: To observe the curative effect of a mandibular anterior colloiter on obstructive sleep apnea (OSA) and to explore its therapeutic principle. To explore the effect of maxillary structure analysis on the prognosis of oral reeler. Methods: Seventy OSA patients diagnosed by polysomnography (PSG) were enrolled in this study. There were 63 males and 7 females with a mean age of (50.5 ± 11.6) years and an apnea index (AI) of 34.9 ± 2 1.3) times / h, night minimum oxygen saturation (6 6 .3 ± 16 .5)%. After the oral diagnosis of dental mouthpiece production, review after 3 months PSG examination. Each patient before treatment were taken with and without mouth straightening capitatum flaps two cases of maxillofacial structure analysis. Results: The AI decreased from (34.9 ± 2.1) / h to (15.6 ± 19.2) h / h (P <0.01), the nighttime oxygen saturation decreased from .3 ± 16.6%) to (74.1 ± 15.5)% (P <0.001). A total of 45 patients with AI reduction ≥ 50%. Patients with good response were more obvious contraction of the jaw, the length of the front of the upper part of the mouth after the correction of the jaw prominent protrusion, the upper airway diameter broadening, shortening the length of the upper airway area increased. CONCLUSION: Orthodontics has definite curative effect on some patients with OSA. Its therapeutic effect may be mainly related to the improvement of the relationship between the upper airway structure and the airway patency during sleep.
