Ear-Nose and Throat Doctor (ENT) Questions Sinusitis

Could a sinus infection cause bad breath?

I usually get a sinus infection every year. I have also observed every time I am down with a sinus infection I have bad breath. Are the two connected? If so, why?

Could be. Probably exhaling odors through nose. Bad breath frequently related to dietary intake, e.g. onions, garlic, etc., poor dental care
