摘要
目的本研究通过对OSAS患者上气道截面积与线距测量的分析,探讨上气道的阻塞部位及截面积与线距之间的关系。方法对10例确诊为OSAS的患者行上气道CT三维重建,测量硬腭后区(retrouranalregion,RUN)、悬雍垂后区(retrouvularegion,RUL)、舌根后区(retroglossalregion,RG)及舌骨后区(retrohyoidregion,RH)截面积及矢径与最大横径。结果RUN、RUL、RG区截面积与矢径呈显著正相关,RH区截面积与矢径呈正相关;RUN、RG及RH区截面积与最大横径呈显著正相关。结论OSAS患者上气道狭窄以软腭后区最为常见,舌根后区次之。上气道截面积与矢径及横径有相关关系。
Objective To study the relationship between the cross-sectional area and liner distance of the upper airway space of the patients with obstructive sleep apnea syndrome(OSAS).Methods Airway CT was obstained and 3-dimensional airway models were constructed prospectively for 10 patients with OSAS. The cross-sectional area and linear distance were obstained from the retrouranal region(RUN), retrouvula region(RUL), retroglossal region(RG) and retrohyoid region(RH).Results The cross-sectional area were significantly related to the radius vectors in the airway space of the RUN, RUL, RG and RH; but the transverse diameter had no correlation with cross-sectional area in the airway space of the RUL.Conclusion Airway obstruction in OSAS occurs predominantly at the RUL and RG. The cross-sectional area is related to the linear distance in the upper airway space.
