Abstract

Five patients with dacryocystorhinostomy failures were examined with computed tomography or computed tomographic dacryocystography. In computed tomographic dacryocystography, radiopaque dye was instilled into the lacrimal sac before computed tomography to show its shape, location, and relation to surrounding structures. Problems with the bony ostium were detected in all five patients. Recurrent nasal polyposis, a retained metallic clip, and an unresected ethmoid air cell were also identified. Computed tomography and computed tomographic dacryocystography provided important information that facilitated reoperation after dacryocystorhinostomy failure.

摘要

对5例泪囊鼻腔吻合术失败的患者进行了计算机断层扫描（CT）或CT泪囊造影检查。在CT泪囊造影中，在进行CT扫描前将不透射线的染料注入泪囊，以显示其形状、位置以及与周围结构的关系。所有5例患者均检测到骨性造口存在问题。还发现了复发性鼻息肉、残留的金属夹和未切除的筛窦气房。CT和CT泪囊造影提供了重要信息，有助于泪囊鼻腔吻合术失败后的再次手术。
