摘　　要：目的应用64排螺旋CT三维重建技术观察骨性鼻泪管的解剖特征，为临床安全操作鼻背缩窄截骨术提供参考和理论基础。方法应用螺旋CT对40例正常成人行头部容积扫描，头颅及骨性鼻泪管三维重建，测量鼻泪管相关解剖学数据，观察鼻泪管与周围结构的关系，分析截骨可能损伤鼻泪管的部位。结果测量骨性鼻泪管长为（11．49±1．55）mm；泪管到鼻颌沟的距离：顶部（3．51±1．22）mm，中部（4．95±1．55）mm，底部（5．50±1．80）mm；鼻泪管内壁厚度（1．17±0．53）mm；鼻面角度126．08°±9．45°；鼻泪管长轴与正中矢状切面投影的夹角8．28°±0．73°；水平切面夹角73．79°±3．95°；冠状切面夹角12．12°±1．25°。结论螺旋CT三维重建技术是测量成人鼻泪管解剖学数据的一种有效方法，所得解剖学数据对安全操作鼻背缩窄截骨术有重要的指导作用。Objective To investigate the anatomical character of nasolacrimai dust by 3D reconstruction based on the data of 64-row helical computed tomograph （ CT）, and provide anatomical bases for nasal osteotomies. Methods Head volume, 3D reconstruction of skull and bony nasolacrimal dust from 40 adult volunteers were taken by spiral CT scans, the relatively anatomical data about nasolacrimal dust were measured, the relation between the nasolacrimal dust and its surrounding structure, and then possible injuries of nasolacrimal duct osteotomy were analyzed. Results The length of nasolacrimal duct was （ 11.49 ± 1.55 ） mm ; the distances between nasolacrimal duct and nasomaxillary groove were （ 3.51 ±1.22 ） mm in the top, （4.95 ±1.55 ） mm in the middle and （5.50 ±1.80） mm in the bottom respectively ; the thickness of inner wall was （ 1.17 ±0. 53 ） mm ; the angle between nose and face was 126.08° ±9.45°; the angles between long axis of nasolacrimal duct and projection of vertical plane, horizontal plane and coronal plane were 8.28° ±0. 73°, 73.79° ± 3.95° and 12.12°± 1.25° respectively. Conclusion It is an effective method to measure the anatomical data of nasolaeritual duct by 3D reconstruction technology of spiral CT, and the data obtained from it play an important role in safely operating the nasal osteotomies.
