PURPOSE To evaluate the efficacy of a sleeve technique during endoscopic dacryocystorhinostomy (DCR) in primary nasolacrimal duct obstruction (NLDO) patients with a high lacrimal sac. MATERIALS AND METHODS The medical records of 45 patients (49 cases) undergoing endoscopic DCR for primary NLDO with a high lacrimal sac were retrospectively reviewed. In 19 patients (21 cases), the thick maxilla...

The objective of present study was to compare the results of endonasal endoscopic dacryocystorhinostomy and external dacryocystorhinostomy. It was a prospective non-randomized study. Forty consecutive patients having complaints of watering with complete naso lacrimal duct obstruction were selected for the study. Dacryocystography was done in all the cases. Selection of type of operation was lef...

BACKGROUND Nasopharyngeal carcinoma (NPC) involves the orbits through direct extension to the orbital apex via the cavernous sinus. Anterior orbital masses are very rare with only a few anecdotes in the literature about an anterior spread via nasal cavity or tumour arising de novo from the lacrimal sac. Reactive lymphoid hyperplasia in the orbit has never been reported in association with NPC. ...

Ultrastructural localization of Na+, K(+)-ATPase in the exorbital lacrimal gland of rat was investigated quantitatively by protein A-gold technique. Na+, K(+)-ATPase was purified from the rat kidney, and anti-holo Na+, K(+)-ATPase antibody was obtained from the rabbit by injecting the purified enzyme. A specific antibody against the alpha-subunit of Na+, K(+)-ATPase was affinity purified. Immun...

Aim: To investigate the efficacy of probing in adults with epiphora due to nasolacrimal duct obstruction. Patients and methods: A retrospective study was conducted to investigate the efficacy of probing and irrigation of 72 lacrimal systems in 60 adults with nasolacrimal duct obstruction where epiphora was the only symptom. At follow-up, the procedure was considered successful if the epiphora h...

Introduction Mucoceles are benign expansive cystic formations, composed of a mucus-secreting epithelium (respiratory or pseudostratified epithelium). Nasolacrimal mucocele occurs in a small proportion of children with nasolacrimal duct obstruction and is characterized by a cystic mass in the medial canthus with dilation of the nasolacrimal duct; although dacryocystoceles are rare in adults, the...

PURPOSE To compare the conjunctival, lacrimal sac, and nasal flora cultures and conjunctival normalization time following external (EX-), endoscopic (EN-), and transcanalicular multidiode laser (TC-) dacryocystorhinostomy (DCR) and to evaluate the relationship between culture positivity and surgical success. We further performed antibiotic sensitivity analyses for lacrimal sac culture samples. ...

The sites of physical migration of adult Ascaris include a biliary duct, liver parenchyma, pancreas, peritoneum, thoracic cavity, lacrimal duct, Eustachian tube, fallopian tube, brain, and even a pulmonary artery.1 Areas that are not organically part of the Ascaris migration pattern are accessed through fistulization from sites that are normally infested with Ascaris. Only a limited number of r...
