Abstract：
:Bacterial biofilms have been found in many human bacterial infectious processes including chronic rhinosinusitis. It was found also at the surface of nasal polyps, and both at the surface of the nasal part and the stalk of the antrochoanal polyp. However, our recent research clearly demonstrated the presence of the biofilm at the surface of the mucosa of the healthy paranasal sinuses as well. Our hypothesis therefore is that the biofilm in the nose and paranasal sinuses is nothing else but regular respiratory mucosal blanket, a part of the mucociliary system itself, containing variable number of bacteria.
