A mucocele is a ball of concentrated mucus surrounded by a layer of pseudo-stratified columnar epithelium. It gradually grows and slowly expands in a paranasal sinus cavity, and even erodes the adjacent structures. Most paranasal sinus mucoceles occur in the frontal and ethmoid sinues. Mucoceles are usually unilateral, and are rarely bilateral (4%).

鼻窦黏液囊肿是鼻窦黏液被伪复层柱状上皮(pseudostratified columnar epithelium)所局限，在鼻窦内逐渐成长与扩张，甚至侵犯到邻近的结构，好发於额窦及筛窦，且多为单侧病灶，双侧较为少见(4%)。
