【摘要】 目的:探讨颅咽结构改变量与疗效相关关系。方法:选取行口腔矫治器治疗的阻塞性睡眠呼吸暂停综合征患者14人,戴口腔矫治器前及戴用口腔矫治器1~3个月后摄头颅定位侧位片及行多导睡眠图检查,分析治疗疗效,对11项颅咽结构变化量与疗效行相关关系分析。结果: 14例患者戴用口腔矫治器后均取得较好疗效,下气道间隙与低通气指数、舌背至腭平面距离与呼吸暂停指数、下颌平面角与呼吸紊乱指数的变化量均呈正相关关系。结论:矫治器设计中下颌的移位应尽量减小下颌平面角的增加量及舌背的下移量。更多还原

【Abstract】 Objective: To investigate the correlation between the effect of dental appliance on Obstructive Sleep Apnea Syndrome(OSAS) and the structive changes of craniopharynx before and after the oral appliance therapy. Methods: Fourteen OSAS patients (11 men and 3 women) who were treated by the oral appliance therapy were involved in the research. Each patient underwent cephalometric film and polysomonography before and after one to three month oral appliance therapy. Sleep parameters and eleven cephalometric items were analysed. Statistic T test and Pearson’s or Spearman’s correlations were performed. Results: Forteen OSAS patients obtained agreeable effects after the oral appliance therapy. The correlations between the change of the sagittal dimension of lower air way space and Hypopnea Index(HI), the change of the distance from the lingual dorsal to the palatal plane and the Apnea Index(AI), the change of the mandibular plane angle and the Apnea Hypopnea Index(AHI) are positive. Conclusion: The smaller the changes of the manilibular plane angle and the distance from the lingual dorsal to the palate plane when OSAS patien wear the oral appliance,the more effective the oral appliance therapy.更多还原
