Endoscopic Endonasal Approach Animation

April 22, 2009 -- This animation shows how a large brain tumor near the pituitary gland can be removed through pioneering endoscopic endonasal (through the nose) surgery at UPMC. This minimally invasive technique allows surgeons to remove skull base tumors as large as softballs through the nose, with less trauma to the brain and critical nerves than with a traditional craniotomy.
