A mucocele results from obstruction of the drainage of a paransal sinus - resulting in expansile remodeling of the bone walls, surrounding a fluid filled space. These are most common in the frontal sinus. Obstruction of a single mucus gland creates a retention cyst, usually small and often asymptomatic - these are most common in the maxillary antrum.
