A Case of Ethmoid Mucocele

ABSTRACT

Mucocele is a chronic, expansile, cyst-like lesion of the paranasaI sinuses. They contain sterile mucoid material and are lined by mucosa of the affected cavity. Mucocele develops when drainage of normal sinus secretion is obstructed usually by scarring, inflammation, trauma, and tumor. Most of the mucocele are found in the frontal sinus and anterior ethmoid sinus. They may present ophthalmic manifestations such as exophthalmos, displacement of the eye, and limitation of eyeball movement. We experienced a case of left ethmoid mucocele in a 48-year old man. Histologic examination confirmed the mass to be mucocele of the ethmoid Sinus.
