Hi, I've suffered from on and csf leaks from my skull base for many years that were repaired.
They can be serious or not, depending on the rate of flow. The main risk is that they provide an entry point for meningitis, which can be fatal. So if you have a high fever go to the Emergency room ASAP.
Ive had two repair surgeries as well. I cannot diagnose u but as a fellow sufferer I urge u to advocate for ur self. Also I will share a bit about how my leaks were diagnosed.
One test that I've had a few times:, a dye was injected into the dural space via a lumbar puncture. Then pledgelets ( cottony tampon type things) were inserted by an ENT high up into my sinuses. I think they put three on eachside? Then, over the course of a few days nuclear CTscans were done to my skull base to try and locate the leak. In my case, the pledgelets had CSF but the scans did not show much. Both times I had skull base surgery done by an ENT surgeon thru the nose.
Small leaks can sometimes seal up on their own if u go onto bed rest, lay flat, use caffiene for a couple of weeks. It is hard to do this without help. If the leak is larger u made need surgery. I had a third leak coming from my ear that self sealed.
My last lumbar puncture showed my pressure to be normal and I am not having the low pressure headaches any more. So in my case, I'm ok now.
I hope that this helps.
