摘要/Abstract

摘要： 目的:研究下颌前伸矫治器对阻塞性睡眠呼吸暂停综合征(OSAS)患者的疗效及机制。方法:采集80例OSAS患者应用下颌前伸矫治器治疗前、后的CT数据,利用三维影像重建技术测量上气道结构及容积变化,评价口腔矫治器(OA)的疗效及机制,采用SPSS17.0软件包对数据进行方差分析。结果:下颌前伸矫治器治疗OSAS多数患者主观症状缓解或消失,客观检测指标相应改善。OSAS患者存在上呼吸道的解剖性狭窄,戴入OA后,气道各分段截面积和容积均有变化,腭咽、喉咽段增大(P＜0.01),口咽段减小(P＜0.05)。结论:OSAS存在形态学病因机制,下颌前伸矫治器通过前伸下颌骨,使上气道减小,内部变化而更平滑稳定,减小涡流和狭窄,进而发挥治疗效果。

Abstract: PURPOSE: To investigate the efficacy and mechanism of mandibular advancement device (MAD) treatment on obstructive sleep apnea syndrome (OSAS) patients. METHODS: Eighty OSAS patients treated with a mandibular protraction appliance were included in the study. Three-dimensional reconstruction technique was used as to measure the changes of upper airway structure and volume before and after MAD treatment. The data was analyzed using SPSS 17.0 software package. RESULTS: The anatomic structure and the reinforcement of soft tissue's collapse in the upper airway changed after application of MAD in OSAS patients; velopharyngeal and laryngopharynx configuration was significantly increased (P<0.01), while oropharyngeal configuration was significantly decreased (P<0.05). CONCLUSIONS: This study demonstrated that pathogeny of OSAS based on morphological characteristics may be removed by mandibular advancement device, the mechanism of efficacy of MAD treatment can be the reduction of airway internal fluctuation and vortex of air.
