Mucopyocele of the maxillary sinus

Abstract

Mucoceles are defi ned as chronic, cystic lesions in the paranasal sinuses. When the mucocele content

becomes infected, the lesion is defi ned as mucopyocele. Most mucoceles are located in the frontal

and anterior ethmoid sinuses and normally they involve the frontal-ethmoid complex, expanding to

the superior-medial region of the orbit, leading to ocular disorders; maxillary sinus presentation is

rare. In the present article, the authors described a rare case of mucopyocele in the maxillary sinus.

Key Words: Mucocele, mucopyocele, paranasal sinus
