Fibrous dysplasia of the paranasal sinuses is mostly asymptomatic, but sometimes may cause signs and symptoms depending on its location. We report two cases of maxillary fibrous dysplasia obstructing the lacrimal drainage system as a reason of chronic dacryocystitis, and reviewed the related literature. The first case underwent an endonasal endoscopic approach combined with external dacryocystorhinostomy. He had a patent lacrimal system at one-year follow-up. The lesion was completely removed via an endonasal endoscopic approach in the second case, wherein the patient was asymptomatic of the six-month follow-up period.
