What surgeries are there for pseudotumor cerebri?

Surgeries performed for treatment of pseudotumor cerebri focus on lowering intracranial pressure. Optic nerve sheath fenestration involves cutting a hole in the membrane around the optic nerve in order to relieve the pressure. Another method involves a spinal fluid shunt. This involves placing a long tube inside your body in order to redirect excess cerebrospinal fluid. Both of these methods can be successful, but have risks.
