What is the chance I will have a spinal fluid leek and need surgery again?
If you have a pituitary tumor or another tumor in which there is no plan to open the lining of the brain (dura), then your chances of having a postoperative leak and requiring follow-up surgery is very low (less than 2%). On the other hand, if you have a tumor that requires the surgeons to open the lining of the brain through the nose, as for meningiomas and craniopharyngiomas, the risk is a little higher. With the development of the nasoseptal flap (vascularized tissue from the patient’s own nose that is transplanted from the septum to the skull base), the chance of having a spinal fluid leak after surgery is just 5.4%.
