If you haven’t yet seen this brief video of three-year-old Grayson Clamp hearing his daddy’s voice for the first time, watch it now — grab a tissue first.
Grayson Clamp was born without his cochlear nerves, or the auditory nerve that carries the sound signal from the cochlea in the inner ear to the brain. His parents tried giving him a cochlear implant, but it did not work.
They then enrolled Grayson in a research trial at University of North Carolina Hospitals in Chapel Hill, N.C. Three weeks ago, he became the first child in the U.S. to receive an auditory brain stem implant.
What a wonderful achievement for this sweet little boy.
