A retrospective analysis of 100 coronal sinus CT scans was performed to investigate the frequency of opacity of the nasolacrimal duct and determine if there was any correlation between the pattern of duct opacity and the presence of inflammatory sinus disease. The study showed that the nasolacrimal ducts are opaque in the majority of normal people and that there is no relationship to inflammatory sinus disease.
对100例冠状窦CT扫描进行回顾性分析，以研究鼻泪管阻塞的频率，并确定泪管阻塞模式与鼻窦炎性疾病的存在之间是否存在任何相关性。研究表明，大多数正常人的鼻泪管是阻塞的，并且与鼻窦炎性疾病无关。
