I had a cat scan that revealed mucosal thickening throughout the paranasal sinuses. The report stated that the ostiomeatal complexes, sphenoemoidal recesses, and front oethmoidal recesses are opacified. Will you please explain what this information means and more importantly, how it can be treated. I am constantly stuffed and have tried many nasal sprays, decongestants, and antihistamines. Thank you.
