Dacryocystocele; newborn; endoscopic endonasal marsupialisation Abstract. Congenital dacryocystocele: five clinical cases. Congenital dacryocystocele (CDC) is recognised as a cause of nasal airway obstruction or respiratory distress in newborns. CDC is caused by the distal obstruction of the lachrymal duct and presents as a cystic formation in the inferior meatus. We discuss five cases of dacryocystocele, together with surgical management and outcome. Endoscopic endonasal marsupialisation and appropriate postoperative care resulted in definitive recovery for all patients. In newborns or infants with nasal obstruction, CDC should be considered in the differential diagnosis, and prompt endoscopic endonasal marsupialisation is mandatory.
