APPLETON, WI (WTAQ) - Doctors at UW Madison have found a way to quiet down autistic children who scream loudly-and-often.
In the Journal of Voice, UW Health surgeon Seth Dailey wrote about an operation he performed in 2011 on 16-year-old Kade Hanegraaf of Appleton.
His mother Vicki said her son use to scream louder than a lawn-mower, well over a-thousand times each day.
She said it was horrific, and she and her son couldn't go anywhere because of it.
Dailey separated the cartilage in Kade's vocal cords. It formed a larger gap for the boy's air flow, and limited his sound power.
Since then, the doctor said Kade has screamed 90-percent less often -- and it's only been half as loud. He noted that the surgery is reversible.
