This is really challenge question. Based on your description, I think your
child had "cleft uvula" or "submucosal cleft". You can google the images
using these key words.
In fact, it is not easy to find. You are lucky that an experienced
pediatrician finds it.
Since you are in Indiana, the best hospital for child is Riley Hospital in
Indianapolis. And there is Dental school too.
You need to contact "department of pediatric dentistry in Indiana dental
school" to schedule an appointment. Usually they are associated with a "
cleft team", which includes pediatrician, pediatric dentist, plastic surgeon
, orthodontist. I wish your child has a comprehensive exam by "Cleft Team".
I was used to be a "Hoosier". If you have any question, feel free to contact
me.
