안근 마비를 동반한 접형동 점액낭종

Mucocele is chronic, expansile cyst-like lesions of the paranasal sinus. Mucocele of sphenoid sinus is rare. The first description of a sphenoid mucocele was by John Berg in 1889. Seventy to eighty cases reported in the literature. In the Korean literature, 8 to 10 cases reported including visulal loss. As the mucocele enlarges, there is pressure resorption of the surrounding bone, exposing and stretching of the dura with pain, and involvement of contigious vital structures. We have recently experienced a case of sphenoid sinus mucocele which presented with ophthalmoplegia. This case was treated by sphenoidotomy using modified sublabial transseptal approach.
