Abstract

Patients who suffer from epiphora can benefit from reconstructive surgery in many cases of obstructive and nonobstructive lesions of the lacrimal apparatus. We describe our technique of digital subtraction macrodacryocystography (DSM) and discuss its efficacy in the evaluation of various abnormalities involving the lacrimal drainage pathway. A variety of pathologic conditions of the lacrimal apparatus are portrayed. DSM is an accurate, easy to perform, but relatively unrecognized method of anatomic localization of obstructive lesions within the lacrimal drainage system.

摘要

在泪器阻塞性和非阻塞性病变的许多病例中，患有泪溢的患者可从重建手术中获益。我们描述了数字减影泪囊造影术（DSM）的技术，并讨论其在评估泪液引流途径各种异常情况中的疗效。文中描绘了泪器的多种病理状况。DSM是一种准确、易于操作，但相对未得到充分认可的泪液引流系统内阻塞性病变的解剖定位方法。
