A CSF leak can either be repaired from the brain or sinus side of the skull. Our team of sinus surgeons are specialized in sinus CSF repairs, which tend to have a higher success rate than those repaired on the brain side. Our surgeons perform a CSF leak repair through the nasal cavity using an endoscope. Most often, this procedure does not require a facial incision. Though in some cases where the leak is located directly above the eyes, a small incision is required.
Once the defect is located, the surgeon removes the mucosa (nasal and sinus lining) to allow an unobstructed view of the defect. Depending on the size of the repair, the surgeon then places one or more layers of support to plug the defect. Once the surgeon confirms that the support has stopped the CSF leak, he or she will add packing and sealants to further help the repair.
Depending on the patient, our surgeons may place a lumbar drain after surgery to run the CSF fluid away from the repair site in order to reduce pressure. We recommend bed rest for up to a week after the repair. Fortunately, the success rate of endoscopic nasal CSF leak repairs range above 90%.
