Son John, 15 yrs.old is a trumpet player and has developed VPI. It was his first year of marching band, played in a big competition on 10/10 and has not been able to play any high notes on trumpet since. Air escapes out his nose-soft palate is not closing. Been to every doc under sun.Done CT,MRI,Swallow tests. All normal. Been to speech Therapist-nobody has any advice or help.Drs. has never heard of VPI until I provided them with the literature, which is slim. Last ENT pretty much suggested that John quit playing which he does not want to do. He took 4 weeks off from playing Oct.-Nov. then one doc said that it probably wouldn't hurt, so he began again;it has not improved. (It had improved from onset because at first when he drank anything it would come directly out nose--this cleared up after two weeks of rest).Now I am searching for any advice from the music community.
