The technique of computed tomographic dacryocystography is described. It was developed in response to the pre-operative imaging requirements for transnasal endoscopic dacryocystorhinostomy, a new minimally invasive operation performed as a primary procedure to relieve epiphora. However, it is also helpful in the assessment of patients after failed conventional external dacryocystorhinostomy when the information provided will help to determine the subsequent surgical approach. In addition the technique will assist surgical planning in cases of epiphora associated with sinus surgery, facial trauma and maxillofacial tumours by determining the site and extent of pathology.
本文描述了计算机断层扫描泪囊造影技术。该技术是为满足经鼻内镜泪囊鼻腔造口术的术前成像需求而开发的，这是一种新的微创手术，作为缓解溢泪的主要手术进行。然而，当传统外路泪囊鼻腔造口术失败后，该技术在评估患者时也很有帮助，因为所提供的信息将有助于确定后续的手术方法。此外，该技术通过确定病变的部位和范围，将有助于与鼻窦手术、面部创伤和颌面肿瘤相关的溢泪病例的手术规划。
