Abstract

Neonatal respiratory distress is a commonly seen entity whose causes are legion. Nasal obstruction secondary to intranasal masses is significant because neonates are obligate nasal breathers. Congenital nasolacrimal duct obstruction (NLDO) causing respiratory distress is an extremely rare event since most cases of NLDO do not compromise the nasal airway. We report two cases of neonatal respiratory distress secondary to bilateral NLDO with cystic mucocele formation and intranasal extension; only two similar cases have been previously described. Pertinent embryology and anatomy are reviewed as is a brief discussion of congenital NLDO. MRI and a nasal endoscopic photograph are provided demonstrating the nasolacrimal and nasal pathology. Treatment strategies are outlined. Consideration of nasolacrimal duct pathology in the differential diagnosis of neonatal respiratory distress and nasal obstruction is stressed.
