目的:应用螺旋CT三维重建技术探讨正常婴幼儿鼻泪管的解剖学特征.方法:应用螺旋CT对27例(54眼)正常婴幼儿和15例(30眼)成人骨性鼻泪管三维重建后,测量骨性鼻泪管长度,鼻泪管长轴与正中矢状切面,水平切面,冠状切面投影的夹角等解剖学数据,同时用解剖学方法测量7例(14眼)儿童尸头骨性鼻泪管长度作对照,应用SPSS 13.0软件进行统计学处理.结果:螺旋CT三维重建测量婴幼儿骨性鼻泪管长度为10.06±0.29mm,儿童尸头骨性鼻泪管长度为9.95±0.31mm,成人骨性鼻泪管长度为11.51±1.54mm,前两者之间的差异无统计学意义,而两者与成人鼻泪管长度之间的差异有统计学意义.婴幼儿鼻泪管长轴与正中矢状切面投影的夹角为7.96°±1.62°,与水平切面投影的夹角为73.24°±6.75°,与冠状切面投影的夹角为12.31°±2.03°;成人鼻泪管长轴与正中矢状切面,水平切面,冠状切面投影的夹角分别为8.08°±0.63°,72.69°±3.85°,12.09°±1.21°,两者之间无显著性差异.结论:螺旋CT三维重建技术是测量婴幼儿鼻泪管解剖学数据的一种有效方法,所得解剖学数据对婴幼儿泪道疾病的手术治疗有重要的指导作用.

AIM: To measure the anatomical character of nasolacrimal dust by spiral CT 3D reconstruction in children.METHODS: The length of nasolacrimal dust and the angles between nasolacrimal dust and vertical plane,horizontal plane and coronal plane in 27 children(54 eyes) and 15 adults(30 eyes) were surveyed using spiral CT 3D reconstruction. While the length of nasolacrimal dust in 7 dead children(14 eyes) body were surveyed as comparison by anatomical method. The RESULTS: were analyzed by software SPSS 13.0 statistically. RESULTS: The length of nasolacrimal dust was 10.06±0.29mm in children and 11.51±1.54mm in adults by spiral CT 3D reconstruction,as 9.95±0.31mm in dead children body by anatomical method,with significant statistical difference between that of children and adults. The angles between nasolacrimal dust and vertical plane,horizontal plane and coronal plane in children were 7.96°±1.62°,73.24°±6.75°,and 12.31°±2.03° respectively,while the corresponding angels in adults were 8.08°±0.63°,72.69°±3.85° and 12.09°±1.21°. The difference between them had no statistical meaning. CONCLUSION: The anatomical data of children nasolacrimal dust obtained from spiral CT 3D reconstruction have important guidance to the therapy of nasolacrimal dust diseases in children.
