Cerebrospinal fluid (CSF) fills the space around the spinal cord and the brain, and is contained by a covering called the dura mater. Any trauma or tear in the dura can allow the CSF to leak.
Treatment of Cerebrospinal Fluid Leaks
Some CSF leaks resolve by themselves after a few days. Most of the cases that do not fix themselves can be repaired endoscopically through the nose. This approach is less invasive and less traumatic than the traditional method of a craniotomy, which involved making incisions through the skull or facial bones. The experts at the Cedars-Sinai Sinus Center have extensive experience repairing CSF leaks using the nasal endoscopic approach.
