The aim of the study was the application of computed tomography (CT) in the evaluation of types of ethmoid morphology. The material consisted of 197 CT examinations performed, using the Somatom AR.T (Siemens) CT scanner, in patients referred for CT for reasons other than sinus pathology. The examinations were performed in 2-mm contiguous axial scans. Ethmoid morphology was evaluated by means of...

Lacrimal punctal agenesis is a rare cause of congenital epiphora and may occur in isolation or in combination with other lacrimal drainage anomalies such as pathologies of the canaliculus, lacrimal sac, and nasolacrimal duct. It rarely occurs in a familial manner. If diagnosed earlier, management of this condition may be as simple as a sharp opening or may necessitate more complex interventions...

Introduction: This study was done to determine the site of obstruction in lacrimal drainage system in Asian patients suffering from epiphora and to determine the transit time taken for the tracer material to reach the lacrimal sac and the nasal cavity. Methods:Dacryoscintigraphy was performed using radionuclide technetium-99m pertechnetate (99m...

Dear Editor, Amyloidosis is a heterogeneous group of diseases characterized by extracellular amyloid deposits in different organs [1]. Deposition may occur secondary to a systemic disease or as primary amyloidosis in absence of a systemic disease. Periocular and orbital amyloidosis are rare, especially in the lacrimal apparatus. In South Korea, only 12 cases of amyloidosis have been reported, a...

We present two patients with dacryoliths and patent lacrimal drainage with intermittent tearing and without infection. Dacryoliths can be present in the lacrimal sac or lacrimal duct without acute or chronic inflammation. In these cases, we believe dacryolith formation was a causative factor of intermittent epiphora even with a patent drainage system, and we propose that dacryoliths and even fu...
