Complicated Fronto-Orbital Mucopyocele Presenting with Proptosis: Case Report

Abstract

Mucoceles are cystic lesions of the paranasal sinuses which develop as a result of accumulation of mucous secretion due to obstruction of the ostium of the sinuses. Despite their benign behavior, they may enlarge progressively and project into adjacent structures by destructing the bony walls of the sinuses. Frontal mucoceles may get infected and extend towards orbital cavity and compress the orbit by eroding the bony walls of the orbital cavity. Endoscopic and external approaches are performed in the surgical treatment. We report a case of complicated fronto-orbital mucopyocele which eroded the orbital roof and extended into the orbital cavity and discuss the surgical treatment strategy under the light of the current literature.
