Clearance of sinonasal secretions is influenced by its rheological properties. The purpose of this study was to describe the rheological properties of sinonasal mucus in patients with CRS and correlate them with disease severity.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Twenty-three adult subjects with CRS underwent collection of sinonasal secretions. Samples were analyzed using the AR2000 cone and plate rheometer (TA Instruments, New Castle, DE) to determine the dynamic viscosity and elasticity. These properties were used to calculate mucus clearance indices. All patients completed the Sinonasal Outcome Test (SNOT-20). Recent sinus computed tomography (CT) scans were electronically reviewed and scored according to the Lund-McKay staging system.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The mean dynamic elasticity and viscosity of sinus mucus at 1 Hz were 78.24 \u00b1 103.4 Pa and 22.09 \u00b1 29.62 Pa, respectively. The mean elasticity and viscosity values at 10 Hz were 118.9 \u00b1 155.5 Pa and 32.36 \u00b1 45.58 Pa, respectively. Three indices of disease severity (SNOT-20 score, Lund-McKay score, and nasal polyps) correlated with increased mucus viscoelasticity and\/or worsened mucociliary clearance indices (MCIs).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>This study establishes the range of rheological properties of sinonasal mucus in patients with CRS and suggests an association between disease severity and MCIs.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.2500\/ajra.2010.24.3420","type":"journal-article","created":{"date-parts":[[2010,2,10]],"date-time":"2010-02-10T20:34:00Z","timestamp":1265834040000},"page":"1-5","source":"Crossref","is-referenced-by-count":19,"title":["Rheologic Properties of Sinonasal Mucus in Patients with Chronic Sinusitis"],"prefix":"10.1177","volume":"24","author":[{"given":"David M.","family":"Saito","sequence":"first","affiliation":[{"name":"Department of Otolaryngology\u2013Head and Neck Surgery, University of California, San Francisco, California"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anh L.","family":"Innes","sequence":"additional","affiliation":[{"name":"Division of Pulmonary and Critical Care, Department of Medicine, University of California, San Francisco, California"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Steven D.","family":"Pletcher","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology\u2013Head and Neck Surgery, University of California, San Francisco, California"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2010,1,1]]},"reference":[{"key":"bibr1-ajra.2010.24.3420","doi-asserted-by":"publisher","DOI":"10.3109\/00016488309132888"},{"key":"bibr2-ajra.2010.24.3420","first-page":"113","volume":"61","author":"Lofdahl C.G.","year":"1980","journal-title":"Eur J Respir Dis"},{"key":"bibr3-ajra.2010.24.3420","doi-asserted-by":"publisher","DOI":"10.1016\/j.prrv.2006.04.199"},{"key":"bibr4-ajra.2010.24.3420","first-page":"249","volume":"17","author":"King M.","year":"1980","journal-title":"Biorheology"},{"key":"bibr5-ajra.2010.24.3420","first-page":"245","volume":"118","author":"Giordano A.M.","year":"1978","journal-title":"Am Rev Respir Dis"},{"key":"bibr6-ajra.2010.24.3420","first-page":"989","volume":"115","author":"Shih C.K.","year":"1975","journal-title":"Am Rev Respir Dis"},{"key":"bibr7-ajra.2010.24.3420","doi-asserted-by":"publisher","DOI":"10.3233\/BIR-1989-26406"},{"key":"bibr8-ajra.2010.24.3420","first-page":"215","volume-title":"The Nose.","author":"Widdicombe J.G.","year":"1982"},{"key":"bibr9-ajra.2010.24.3420","doi-asserted-by":"publisher","DOI":"10.1164\/ajrccm\/141.1.79"},{"key":"bibr10-ajra.2010.24.3420","doi-asserted-by":"publisher","DOI":"10.2500\/105065893781976357"},{"key":"bibr11-ajra.2010.24.3420","doi-asserted-by":"publisher","DOI":"10.1164\/ajrccm.160.2.9805117"},{"key":"bibr12-ajra.2010.24.3420","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365-2362.1985.tb00290.x"},{"key":"bibr13-ajra.2010.24.3420","doi-asserted-by":"publisher","DOI":"10.1053\/hn.2003.v128.amhn0312811"},{"key":"bibr14-ajra.2010.24.3420","doi-asserted-by":"publisher","DOI":"10.1016\/S0194-59989770005-6"},{"key":"bibr15-ajra.2010.24.3420","doi-asserted-by":"publisher","DOI":"10.2500\/ajr.2008.22.3185"}],"container-title":["American Journal of Rhinology &amp; Allergy"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.2500\/ajra.2010.24.3420","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/full-xml\/10.2500\/ajra.2010.24.3420","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.2500\/ajra.2010.24.3420","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,28]],"date-time":"2026-04-28T09:32:32Z","timestamp":1777368752000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.2500\/ajra.2010.24.3420"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2010,1]]},"references-count":15,"journal-issue":{"issue":"1","published-print":{"date-parts":[[2010,1]]}},"alternative-id":["10.2500\/ajra.2010.24.3420"],"URL":"https:\/\/doi.org\/10.2500\/ajra.2010.24.3420","relation":{},"ISSN":["1945-8924","1945-8932"],"issn-type":[{"value":"1945-8924","type":"print"},{"value":"1945-8932","type":"electronic"}],"subject":[],"published":{"date-parts":[[2010,1]]}}}
