Meningocles with very small communication within the normal subarachnoid spaces appeared the most suitable to be cured by an endoscopic procedure. In case of a larger communication, the meningocele could be treated, or at least the morphology can be better understood, by using a keyhole procedure under endoscopic control. In all cases the surgery was of short duration (less than 1 hour) and very well tolerated.
