Abstract
BACKGROUND: Epiphora is a common problem evaluated by ophthalmologists and otolaryngologists. It is typically the result of obstruction at some level of the nasolacrimal system, either the canaliculi, sac, or duct. Multiple etiologies exist, including scarring from infection or trauma, tumors, or masses. Cysts of the nasolacrimal duct orifice (dacryocystoceles) in the inferior meatus have been described in neonates, usually presenting as obstructive nasal masses shortly after birth. Nasolacrimal duct orifice cysts have not been described in the adult population in the medical literature. PATIENTS: Three patients were identified with epiphora as a result of cysts in the inferior meatus at the opening of the nasolacrimal duct. All patients presented with constant epiphora and were referred for dacryocystorhinostomy by an ophthalmologist or an otolaryngologist. None of the patients had a previous history of nasolacrimal duct (NLD) surgery. One patient had previous endoscopic sinus surgery for nasal polyps. Cysts were identified by nasal endoscopy of the inferior meatus in all patients. RESULTS: All patients underwent endoscopic resection of the inferior meatus cyst to relieve the obstruction of the NLD. Two procedures were performed under general anesthesia and one under intravenous sedation. All patients had complete relief of epiphora and have had no evidence of recurrence of the symptoms or the cyst in 4 to 10 months follow-up. CONCLUSIONS: NLD orifice cysts are easily correctable causes of epiphora. Routine inferior meatus endoscopy should be routinely performed in patients with epiphora to identify whether on not this pathology is present prior to performing dacryocystorhinostomy.
