CSF Leak Closure

CSF Leak Closure: Why It’s Performed

When breaks in the skull base and microscopic tears occur in the tissue surrounding the brain, called the dura, nasal CSF leaks can occur. This is a very serious condition, and these tears must be repaired. Patients who have tears in their dura must have those leaks closed immediately in order to improve headaches and reduce the chance of meningitis.

CSF Leak Closure: What to Expect

Usually performed under general anesthesia, a surgeon will work endoscopically through the nose to identify the leak and repair it using cartilage and other tissue from the ear and nose. CSF leak closure surgery does not involve cutting through the skin, as it is performed entirely through the nostrils. Depending on the size of the leak, most patients will have to stay in the hospital for one to three days after surgery. Some patients may require a lumbar drain that is removed prior to going home.
