Cerebrospinal Fluid Leak

Cerebrospinal fluid surrounds the central nervous system (brain and spinal cord).  Leakage of this fluid from around the brain into the ear or surrounding structures can occur from trauma, surgery, or spontaneous causes.  Surgery is often required to repair the leak.

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.

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