Mucoceles are most commonly frontal or frontoethmoid in origin with maxillary sinus mucoceles accounting for less. Often resulting from trauma or ostial obstruction, mucoceles often expand gradually, but their progression can be much more rapid during episodes of infection. Frequently, the surrounding bone demonstrates either thickening as a result of osteitis from chronic inflammation or remodeling with resorption secondary to the chronic expansile forces and osteolytic enzymes.
