Hey Ted.
The prothesis I was refering to is called an "obturator" and it is for the soft pallet. This is what you NEED. Please read the topic "Dr. Phan, I want your opinion of recontruction" written by August in the "introduce yourself" forum.(this forum) Dr. Phan DDS MS recently came to the OCF forum to volunteer his advice. He is member #4114. You should post him a letter or have him read your topic "Nasal Pharanial-whinning". Once he understands your problem he can guide you. THERE IS NO REASON, for you to not have the abilitly to swallow without having "backwash" through your nasil cavity. I urge you to persue this avenue of treatment. THIS WILL DRASTICALLY IMPROVE YOUR QUALITY OF LIFE! Looking out for you, PeteyB
