This is Dr. David
the best way to tell if you have a risk for infection or aspiration is to get a barium swallow study to see if food and liquids you are eating are trickling into your lungs.
you might benefit from hyperbaric oxygen chamger therapy to introduce new blood flow to the area to help with healing and closure of the fistula.
is this a fistula in your hard or soft palate?
partly on both
have you had a barium swallow study before?
I would ask your doctors for a barium swallow study.
but if you have not had an infection in 3 years, most likely you will not get an infection because of food and drink.
you might experience food or drink going up into your nasopharynx through the fistula, but it should come back down because of gravity.
does this help?
do you have other questions?
ok thanks no other questions
you are welcome
