Can I get a buccal fat removal if I have constant sinus infections?

Patients who suffer of sinus infections could undergo buccal fat removal ONLY IF there is no active sinus infection at the time of the surgery. 

You should be able to have buccal fat removal, but an in-person evaluation is necessary. Buccal fat excision is an appropriate surgical procedure for patients that of overly full and wide cheek areas. In common terms, it is good for patients who have chipmunk cheeks. It can give good results if you're a candidate. You are a patient that would need an in person consultation for a complete evaluation and explanation of the positives and negatives of these procedures in your situation.
I hope this helps
