Endoscopic Repair Of A Sphenoid Fluid Leak

Maine rates for HCPCS 31291

Seals a leak of the fluid that surrounds the brain where it escapes through the sphenoid sinus, the air space deep behind the nose at the base of the skull. The surgeon works entirely through the nostril with a telescope and patches the defect with tissue or graft material. Sealing it stops clear fluid dripping from the nose and removes the risk of meningitis.
