The surgery to remove tonsils is called a tonsillectomy.
After this operation, kids usually don't have as many sore throats. And, if they were having trouble breathing at night, that problem goes away, too. Without tonsils, a kid won't look any different and won't have any scars that anyone can see. You don't need your tonsils, so a kid's body keeps on working just fine even after they've been removed.
