1. A method for treating rhinosinusitis and other bacterial sinus conditions, which method comprises:
- a) applying an aqueous solvating system comprising a metal ion sequestering agent and a surfactant to a treatment site comprising a bacterial biofilm comprising an extracellular polysaccharide matrix attached or adhered to a surface within a nasal or sinus cavity,b) detaching, removing or otherwise disrupting at least a part of the biofilm by solvating the extracellular polysaccharide matrix so as to provide greater than a 1-log order reduction in one or more of Staphylococcus aureus, Pseudomonas aeruginosa, S. pneumonia, Haemophilus influenzae or Moraxella catarrhalis bacteria, and thenc) applying to the treatment site a protective layer of a polymeric film-forming sealant.
