To study computed tomographic dacryocystography used in endoscopic intranasal dacryocystorhinostomy preoperatively.
Ten volunteers and twelve patients with dacryocystitis were undergone the coronary and axial computed tomographic dacryocystography.
According to the anatomic relationship between anterior ethmoid sinus and fossa of lacrimal sac, the cells of anterior ethmoid sinus were classified into three typies: the result was that type I accounted for 12 sides (27.3%), type II 18 sides (40.9%), type III 14 sides (31.8%) by analysing the data of axial dacryocystographies; the sites of obstruction were connection of the lacrimal sac with nasolacrimal duct, the form of lacrimal sac of 11 patients was normal or enlarged lacrimal sacs, bilateral cricatrized lacrimal sacs were found in one patient by analysing the data of coronary dacryocystographies.
Computed tomographic dacryocystography preoperatively can provide significant clinical guidance for the endoscopic transnasal dacryocystorhinostomy in locating the site of bone-opening.
研究术前计算机断层扫描泪囊造影术在内镜下鼻内泪囊鼻腔造口术中的应用。
对10名志愿者和12例泪囊炎患者进行冠状位和轴位计算机断层扫描泪囊造影术。
根据筛前窦与泪囊窝的解剖关系，将筛前窦气房分为三型：通过分析轴位泪囊造影数据，结果显示I型占12侧（27.3%），II型18侧（40.9%），III型14侧（31.8%）；通过分析冠状位泪囊造影数据，阻塞部位为泪囊与鼻泪管连接处，11例患者泪囊形态正常或增大，1例患者双侧泪囊瘢痕化。
术前计算机断层扫描泪囊造影术可为内镜经鼻泪囊鼻腔造口术的骨孔定位提供重要的临床指导。
