摘要: 目的:研究上颌快速扩弓对安氏Ⅱ类1分类患者上气道体积的影响。方法:选取16例上牙弓狭窄的安氏Ⅱ类1分类青少年患者,使用Hyrax矫治器快速扩大上颌牙弓。将治疗前后的CBCT数据导入Dolphin软件进行测量,对治疗前后数据进行配对t检验(P< 0.05)。结果:扩弓后上气道总体积增加3070.19 mm3,具有显著差异。从各段来看,鼻咽,腭咽,舌咽段体积分别增加1491.62 mm3,624.21 mm3,473.65 mm3,其中只有鼻咽段增加量具有统计学差异。最小横截面积增加25.25 mm2,无统计学意义。结论:上颌快速扩弓对安氏Ⅱ类1分类青少年患者的上气道体积,尤其是鼻咽段体积有一定影响作用。

Abstract: Objective: To assess upper airway changes immediately after rapid maxillary expansion (RME) in Class Ⅱ Division 1 malocclusion adolescent. Methods: Sixteen subjects with Class Ⅱ, Division 1 malocclusion and maxillary transverse deficiency underwent RME. CBCT images were collected pre-RME (T1) and post-RME (T2). Measurements were taken with Dolphin Imaging Software® 11.8. Paried t test (P<0.05) was used to compare differences between T1 and T2. Results: The upper airway volume and nasopharynx volume increased significantly (P<0.05) but there was no significant difference in retropalatal airway volume, retroglossal airway volume, and minimal cross-sectional area. Conclusion: There was significant increase in upper airway volume and nasopharynx volume after RME in Class Ⅱ Division 1 malocclusion adolescent.
