A team of ear, nose and throat specialists and neurosurgeons at the University Hospital of Navarra, led by doctors Manuel Manrique Rodríguez, specialist in ear, nose and throat surgery and Bartolomé Bejarano Herruzo, specialist in paediatric neurosurgery, have successfully operated on a 13 month-old girl from Murcia, who had been born deaf due to the lack of auditory nerves. She is the youngest patient in the world who has received an auditory implant in the brain stem. As a result of the operation, the child has begun to hear and started language development.
