Cerebrospinal Fluid Leak

Indications for Surgery

Leakage of fluid from around the brain into the ear or surrounding structures (trauma, post-surgery, or spontaneous causes) all may be signs that you may need surgery.


This procedure requires a General Anesthetic.

Surgical Time

The length of this procedure is 1 to 5 hours.

Hospital Admission

A hospital admission is required for 1 to 4 days.

About the Procedure

A combination of approaches tailored to the individual site of leakage. Frequently access from above and below the leak is necessary using a mastoid approach and a middle fossa approach. In many situations tissue is used to repair the leak, but bone replacement cements are necessary.

Side Note

Cerebrospinal fluid leakage places the patient at risk for meningitis and needs urgent attention.
