Endoscopic marsupialization of bilateral lacrimal sac mucoceles with nasolacrimal duct cysts

A lacrimal sac mucocele is an uncommon disease usually treated by ophthalmologists. In rare cases, it is sometimes associated with a nasolacrimal duct cyst presenting as an intranasal cystic mass, which needs the involvement of an otolaryngologist in diagnosis and management. Two cases of lacrimal sac mucoceles with nasolacrimal duct cysts are presented with a brief literature review. Both cases presented with intranasal cystic masses that caused nasal obstruction and were cured with endoscopic marsupialization of the cysts.
