Good evening doctors. can you have complete opacification of the left frontal sinus and feel fine and not have symptoms of illness?

You describe the outcome of chronic sinusitis, and likely there is obstruction preventing proper drainage. Best to be proactive here as eventually this could become a source of potential infection. See an otolaryngologist.

Hello, sometimes we see patients referred to us who have an opacification of a sinus, multiple sinuses or even all the sinuses. Our challenge is what to do especially when the patients feel fine. We often times will want to operate to get a biopsy for proper evaluation. Most often it’s related to benign nasal polyps which are not causing infection or inflammation. See your ENT for full evaluation
