Cultures grown from healthy donors may underestimate changes in individuals with chronic sinonasal disease thereby yielding inaccurate results with respect to this large patient population. The purpose of this study was to analyse HSNECs derived from patients with chronic rhinosinusitis with nasal polyposis (CRSwNP) to determine whether expected disease dependent variables salient to topical drug delivery persist in culture.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Methods<\/jats:title>\n                  <jats:p>Cultures were grown from patients with CRSwNP.
