In a prospective survey, 200 cases of operated chronic dacryocystitis were divided into three groups according to the kind of operation, and the respective results are as follows: Group I includes 100 cases in whom the lacrimal bone was removed (8mm x 8mm) and a 6mm diameter catheter was used (as a duct between the lacrimal sac and nasal cavity). The recurrence rate within one year was 24 ...

purpose: to report a case of lacrimal sac lymphoma presenting with nasolacrimal obstruction. patient and findings: a 35-year-old woman presented with epiphoria and swelling of the left lacrimal sac area and cervical lymphadenopathy. she had undergone dacryocystorhinostomy (dcr) 6 months before. computed tomography demonstrated a lacrimal sac mass involving the nasal cavity. histopathologic exam...

Introduction: Dacryocystorhinostomy (DCR), a popular surgical procedure, has been performed using an endoscopic approach over recent years. Excellent anatomical knowledge is required for this endoscopic surgical approach. This study was performed in order to better evaluate the anatomical features of the lacrimal apparatus from cadavers in the Isfahan forensic center as a sample of the Iranian ...

purpose: to report a case of free floating pyogenic granuloma within the lacrimal sac. case report: a 13 month old infant with unresolving dacryocystitis and history of two times failed probing and once failed turbinate fracture was scheduled for dacryocystorhinostomy (dcr). a free floating red mass was removed from the sac. histopathologic examination confirmed a diagnosis of pyogenic granulom...

PURPOSE The purpose of this study was to investigate the prevalence of a common canalicular entrance in the lacrimal sac and to investigate the anatomy of the canalicular/lacrimal sac junction with direct visualization using a novel cadaveric dissection technique. METHODS Preserved cadavers were dissected to allow direct visualization of the canalicular entrance(s) to the lumen of the lacrima...

OBJECTIVE To determine the usefulness of "routine" lacrimal sac biopsy to evaluate unsuspected neoplasm or systemic disease in patients with acquired nasolacrimal duct obstruction. DESIGN Noncomparative, interventional case series with histopathologic correlation. PARTICIPANTS Review of charts revealed histopathologic reports on 302 specimens from 258 patients who had undergone routine dacr...

Dear Editor, Two cases with epiphora and medial canthal mass showed a cyst within the lacrimal sac that compressed the lacrimal drainage system. We describe a new lacrimal sac anomaly of lacrimal intrasaccal cyst, which has not yet been reported. A 31-year-old woman was referred for epiphora in her left eye for 17 years. She also presented with a 10-year history of a palpable mass below the med...

Lacrimal sac diverticulum is a rare condition, and its various symptoms complicate differential diagnosis. We present cases of a peculiar type of lacrimal diverticulum. A 5-year-old girl and a 50-year-old woman presented with a protruding mass inferior to the medial canthus. Each lacrimal system was patent to irrigation. The masses compressed and distorted the lacrimal passage and had no appare...
