Flexible neuroendoscopic treatment of suprasellar arachnoid cysts

Endoscopic treatment of suprasellar arachnoid cysts is now the treatment of choice. By marsupializing the roof of the cyst the condition can be cured. The perceived necessity to open both the roof and the floor is called into question by this paper. Three cases-of suprasellar arachnoid cyst are desc ribed all of which have had successful marsupialisation of the cysts by fle xible neuroendoscopy Flexible neuroendoscopic marsupialization of the cyst by widely opening the cyst roof only is described. This is compared with th e other techniques, and also the endoscopic technique involving opening bot h the roof and the floor of the cyst, a more difficult and potentially dang erous method. Successful treatment of this condition is achieved by marsupi alization of only the roof of the cyst. This is a much safer procedure, and has resulted in a resolution of signs and symptoms in the cases described followed-up between 24 and 28 months from the procedure.
