Retention cysts are common and occur with chronic inflammatory sinus disease. Serous cysts are submucosal collections of fluid. Mucous cysts form as a result of mucous gland obstruction. These cysts cannot be differentiated from one another or from isolated polyps on radiographs. They usually occur in the floor of the maxillary antrum but can be present elsewhere. They are incidental findings in 10% of instances.
