OBJECTIVES Many factors influence the outcome of endoscopic dacryocystorhinostomy (DCR). One of the most important prognostic factors is the level of obstruction in the lacrimal drainage system. The main objective of this report is to evaluate both the frequency of obstruction by anatomical region of the lacrimal drainage system on dacryocystography (DCG) and the surgical outcome of endoscopic ...
Objectives: Malignant lacrimal sac tumors are rare. The therapeutic methods are decided depending on the tumor status and general condition. A multidisciplinary approach may be needed. When necessary, orbital exenteration may be performed. To maintain the quality of life in patients, we applied intra-arterial infusion chemotherapy for locally advanced lacrimal sac squamous cell carcinoma cases....
Linear compartmental analysis was applied to lacrimal scintigraphy data from asymptomatic and obstructed lacrimal systems. Failure to achieve satisfactory results in most of the asymptomatic systems studied suggests that variable tear flow is a feature of normal lacrimal drainage which precludes linear analysis. However, in cases where the analysis was successful the results were consistent wit...
