두개내 침범을 동반한 거대한 전두동 점액낭종 1례

Mucocele is a expansile cyst-like lesion of the paranasal sinus. Most of the mucoceles are found in the frontal sinus and ethmoid sinus, and associated with the blockage of the natural sinus ostium. The authors experienced a case of huge mucocele caused by metallic foreign body injury at Korean war. This mucocele involved both frontal sinus and supraorbital cells. It was firmly attached to dura. This case was successfully treated with external frontal approach and abdominal fat tissue obliteration. Therefore, we present this case with a brief review of the literature.
