摘　　要：目的研究泪道疾病的CT表现,并评价其对诊断与治疗的临床意义。方法 21例泪道疾病患者均经轴位双层螺旋CT薄层扫描,同时采用多平面重组(MPR)方式观察冠状位图像。结果研究证实,本组21例中有泪囊炎5例(24%),鼻泪管阻塞6例(28.5%),单侧鼻骨骨折4例(19%)以及眶内侧壁骨折合并鼻泪管骨折6例(28.5%)。结论薄层螺旋CT扫描结合MRP重组能清晰显示泪道阻塞的部位、范围及其致病原因,对临床明确诊断与选择最佳治疗方案具有重要意义。Objective To investigate CT findings of lacrimal pathway diseases and to evaluate their clinical significance for the diagnosis and treatment.Methods Twenty-one patients with lacrimal pathway diseases underwent axial thin-section spiral CT scans,simultaneously,the coronary images were observed by using multiplanar reformation（MPR）.Results The study demonstrated that there were 5 dacryocystitis（24%）,6 lacrimal duct obstructions（28.5%）,4 unilateral lacrimal duct fractures（19%）,and 6 intra-orbital wall fractures associated with nasolacrimal duct fractures（28.5%） in the group 21 patients.Conclusion Thin-section spiral CT scanning combined with MPR could clearly visualize the site,extent and pathogenic causes of lacrimal pathway obstruction,and therefore it has important significance for clinically definite diagnosis and selecting optimal therapy protocol.
