骨性Ⅲ类不同垂直骨面型成人上气道形态三维测量分析

摘要

目的:比较骨性Ⅲ类不同垂直骨面型成人上气道鼻咽、腭咽、舌咽气道大小的差异,探讨上气道不同部位与颅面部骨骼形态的关系.方法:将62例骨性Ⅲ类成人患者按GoGn-SN角分成高角、均角和低角3组,每位患者进行颅面部锥体束计算机断层扫描(CBCT),并对鼻咽、腭咽、舌咽气道的矢状径、冠状径、截面积以及容积等指标进行测量分析,比较3组之间的差异.结果:骨性Ⅲ类男女上气道各测量值之间比较发现在UTH、UTS、EPV存在明显差异(P＜0.01),其余测量值没有统计学差异(P＞0.05).骨性Ⅲ类不同垂直骨面型男性气道在PNSL、PNSS、UTW、UTV、EPV和V存在明显差异(P＜0.05),而女性在UTL和EPS处存在明显差异(P＜0.05).结论:由于颅面部垂直生长型的不同,骨性Ⅲ类不同垂直骨面型成人上气道大小及形态存在明显差异.%Objective To investigate the characteristics and differences of upper airway in adult skeletal class III with different vertical facial types,and to find out the relation ship of the upper airway and craniofacial characteristic. Methods Sixty-two adult skeletal class III patients were divided into three groups based on their GoGn-SN angles,Three dimensional airway volumes and cross-sectional areas、lengths and widths were measured by using cone-beam computed tomography (CBCT).AII the data were analyzed through the statistical method and compared the differences. Results The upper airway measurement data have significant differences in the UTH,UTS,EPV between male and female (P<0.01),but the rest of measurement data didn't have significant differences (P>0.05).There were significant differences in the PNSL、PNSS、UTW、UTV、EPV and V in the male upper airway, while in female,there were obvious differences in the UTL and EPS (P<0.05). Conclusion There were statistical differences in adult skeletal class III upper airway with different vertical facial types because of different vertical growth patterns.
