CSF leaks and encephaloceles occur when there is a defect in the bony skull base and the lining around the brain herniates into the sinus cavity. This can occur due to prior surgery, trauma or other reasons. If there is a tear in the lining, then CSF, the fluid that surrounds the brain, can leak into the nose. Patients have a drippy nose, like a leaking faucet. CSF leaks and encephaloceles are repaired endoscopically in order to reduce the risk of meningitis or other infections around the brain. Our team has published over 30 articles describing our findings and techniques for repairing CSF leaks and skull base defects after endoscopic surgery and has some of the largest series of these cases in the country.
