title: [Neurosurgical treatment of sphenoidal mucocele by endonasal transseptal endoscopic approach: report of two cases].
abstract: Mucoceles are benign, slowly expansive, mucous-filled cystic lesions that arise in the paranasal sinuses. They most commonly occur in the frontal and ethmoid sinuses and are rarely in the sphenoid sinus. The incidence of sphenoid sinus mucoceles is about 1% of paranasal sinus mucoceles. Almost 200 cases of sphenoidal and or intraselar mucoceles have been reported since the first description by Berg in 1889. Sphenoid sinus mucoceles result from accumulation of secretions due to obstruction of the draining sinus osteum. Clinical manifestations are dependent on the direction of the expansion toward adjacent structures, and are therefore variable. The diagnosis is based on CT and MRI. The neurosurgical treatment was marsupialization of the lesion under endoscopic vision by transseptal approach. We report two cases of sphenoidal mucoceles.
