Endoscopic marsupialization of nasolacrimal duct cysts under topical anaesthesia: 5 years of a single institute experience.

OBJECTIVE: To present the outcomes of neonatal nasolacrimal duct cysts treated through endoscopic intranasal marsupialization under topical anaesthesia. METHODS: A retrospective study of 19 infants diagnosed with congenital nasolacrimal duct cyst, with or without dacryocystocele, diagnosed and treated between March 2015 through March 2020. Data were extracted for descriptive purposes and included: birth weight, main presenting symptom, stertor or dyspnoea, unilateral or bilateral occurrence. Follow-up one month after intervention included recurrence of symptoms, physical examination and fibreoptic naso-endoscopy. RESULTS: Nineteen infants with intranasal cyst were presented to our department at the age of 1 day. Four-teen infants had unilateral and 5 infants had bilateral intranasal cysts. There were 8 boys and 11 girls. Mean gestational age at birth was 39 weeks, mean birth weight was 3351 g. 42.1% of infants presented with dacryocystocele, 31.5% with stertor, and 26.3% with dyspnoea. 80% of infants with bilateral cysts presented with dyspnoea. Follow up ranged from 6 to 48 months, no recurrence of symptoms was reported. CONCLUSION: Intranasal endoscopic marsupialization under topical anaesthesia is a successful, safe, low cost procedure for treating neonatal nasolacrimal duct cysts while avoiding general anaesthesia for infants.
