velopharyngeal insufficiency?
Hi all. I have been experiencing blowback from my nose through my mouth. A chinstrap doesn't help---my cheeks just balloon out. Does anyone else have this problem? It is a tremendous problem with a nose only mask, not so bad with a full face mask. (I think the back pressure reduces the problem.) Does anyone have any thoughts and/or advice? Thanks.
