Physicians perform rare surgery to restore hearing to a deaf patient

Marisela Leon, 44, has neurofibromatosis type 2 -- a rare genetic condition that causes tumors to grow on nerves in the brain or spinal cord, but most commonly on the auditory nerve. Leon lost her hearing more than four years ago when surgery to remove a tumor damaged her auditory nerve.
