Bilateral Congenital Nasolacrimal Duct Cyst: A Rare Cause of Nasal Obstruction.

Nasal obstruction in neonates often results in respiratory discomfort, as neonates are obligate nasal breathers. Congenital bilateral nasal obstruction is an emergency situation which is generally secondary to choanal atresia. Rarely bilateral nasolacrimal duct (NLD) cyst causing intranasal swelling may be the underlying etiology. Neonatal respiratory distress warrants immediate measures to secure the airway and prompt investigations to reach a diagnosis for a definitive management. We describe a case of two-day-old girl with intermittent breathing difficulty because of bilateral NLD cysts causing nasal obstruction. The patient improved with conservative medical management.
