Implant helps toddler hear for first time

An American toddler has been given the chance to hear for the first time in his short life thanks to an implant on his brain stem.

Grayson Clamp, 3, was born without a cochlear nerve which carries sound from the inner ear to the brain.

He was fitted for a cochlear implant but it didn't work. So his parents Len and Nicole Clamp turned to an experimental method that had never before been used on children in the US - an auditory brain stem implant.

Doctors are confident Grayson will gain full hearing.
