전두사골동 점액낭종과 분리된 안와내의 점액낭종

Mucoceles most frequently arise from the frontal sinus and anterior ethmoid air cells, presenting with proptosis, frontal headaches, and reduced ocular mobility. Since it may destruct the adjacent bony structures by pressure, proper treatments are necessary. Various surgical approaches for paranasal sinus mucoceles have been reported. The first is radical exenteration of the mucoceles and its whole lining；the other is marsupialization, leaving part of the lining intact. The authors reported a patient with retrobulbar mucocele that might be extended and then seperated from the frontoethmoidal sinus but those were separated. The patient was successfully treated by endoscopic endonasal marsupialization. (J Clinical Otolaryngol 2008;19:227-230)
