Nasal obstruction in the neonate secondary to nasolacrimal duct cysts.

The neonate is an obligate nasal breather and any form of nasal obstruction causes respiratory distress during feeding and sleeping. We report two patients with unusual causes of respiratory distress secondary to nasolacrimal duct cysts. The failure of the lacrimal duct to perforate at the distal end results in dacryocystitis and cyst formation. Removal of the nasal wall of the cyst resolves the obstruction and the dacryocystitis. The nasolacrimal duct cyst is an unusual, but readily treated, cause of neonatal respiratory distress.
