Endoscopic-assisted contralateral interhemispheric transfalcine keyhole approach for falcine meningioma: How I do it

Although the ipsilateral craniotomy approach has been used for the removal of falcine meningioma (FM), we report a case of FM that was minimally invasively removed using a contralateral interhemispheric approach assisted with endoscopy. We used a contralateral approach with a small craniotomy of the FM. The tumor was detached from the surrounding tissue during internal decompression. It was dissected and coagulated endoscopically in a blind spot under a microscope, and a Simpson Grade I resection was achieved. A small craniotomy with a contralateral interhemispheric approach assisted by endoscopy allowed minimally invasive tumor removal without complications.
