| 摘 要： | 目的获取骨性泪道各项CT测量数据，分析解剖学因素在原发性泪道阻塞（primary nasolacrimal duct obstruction，PNDO）发病中的作用。方法回顾分析18例PNDO患者与88例正常成人鼻窦64层螺旋CT容积扫描资料，测量比较骨性泪道各项数据。结果正常成人骨性泪道最窄处为（4．1±1．0）/mm，原发性泪道阻塞患者骨性泪道最窄处为（4．0±1．1）mm，差异无显著性（P〉0．05）。结论64层螺旋CT容积扫描及后处理技术是准确测量骨性泪道的可靠方法。骨性泪道狭窄并非PNDO唯一致病因素。

| Abstract: | Objective To collect various data of CT measurement of bony lacrimal canal and to explore the roles of anatomic factors in the genesis of primary nasolcarimal duct obstruction ( PNDO ).Methods The data of 64-slice spiral CT scans on 18 patients with PNDO and 88 healthy control subjects were retrospectively analyzed.Various data of bony lacrimal canal were measured in all the patients and control subjects.Results The narrowest part of the canal did not differ significantly between the patients and the control subjects ( 4.0 ± 1.1 ) mm vs.( 4.1 ± 1.0 ) mm,P ＞ 0.05].Conclusions 64-slice spiral CT scaning is a reliable method to measure bony lacrimal canal accurately.Narrow bony canal is not the only cause of primary nasolcarimal duct obstruction. |
