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.
