Hi, I am scheduled soon for a left temporal craniotomy to repair a CSF leak. The surgeon said there is a hole in my skull. I have had several leaks in the past 10 years, on the ventricles, near the back of my head...and what appears to be two reoccurences--all were addressed endoscopically. I notice morbidity is a concern for craniotomies, complications,...and it does not appear to have a higher success rate; but the surgeon indicates endoscopic repairs are not successful for holes in the skull. He said it is likley a congenital defect, but none of the tests or doctors before mentioned this before. No trauma to the head that can be associated with it. Can such a hole be repaired succussfully by the endoscopic method? Also, i suffer from Trigeminal Neuralgia, the surgeon believes it may also help with this but the risks associated with the craniotomy seem so much higher. I have had 3 CSF surgeries so far, and a couple of leaks resolved on their own. However, this hole (near the Sphenoid sinus) is a different issue.Thank you for your opinions.
