We sought to determine the cross\u2010sectional prevalence of ETD in patients with CRS using the validated Eustachian Tube Dysfunction Questionnaire (ETDQ\u20107) and to correlate ETDQ\u20107 scores with 22\u2010item Sino\u2010Nasal Outcome Test (SNOT\u201022) scores, endoscopy scores, and computed tomography (CT) scores.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>A total of 101 patients with confirmed CRS completed the ETDQ\u20107 and SNOT\u201022 at their initial visit to our rhinology clinic. Lund\u2010Mackay CT and Lund\u2010Kennedy endoscopy scores were also obtained. Spearman's correlation coefficient (\u03c1) was calculated.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Among the 101 patients, 49 patients (48.5%) had an ETDQ\u20107 score of \u226514.5, signifying clinically significant ETD. The mean \u00b1 standard deviation (SD) ETDQ\u20107 score of the entire cohort was 17.8 \u00b1 10.1. There was a moderately strong correlation between ETDQ\u20107 and the SNOT\u201022 ear subdomain (\u03c1 = 0.691,\n                      <jats:italic>p<\/jats:italic>\n                      &lt; 0.001). The correlation coefficient between ETDQ\u20107 and total SNOT\u201022 scores was \u03c1 = 0.491 (\n                      <jats:italic>p<\/jats:italic>\n                      &lt; 0.001), indicating moderate correlation. ETDQ\u20107 scores were poorly correlated to objective measures of sinonasal disease, including Lund\u2010Mackay CT score (\u03c1 = \u22120.055,\n                      <jats:italic>p<\/jats:italic>\n                      = 0.594) and Lund\u2010Kennedy endoscopy score (\u03c1 = \u22120.099,\n                      <jats:italic>p<\/jats:italic>\n                      = 0.334).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Symptoms of ETD are highly prevalent among patients with CRS as documented by patient\u2010reported outcome measures. The correlation between ETDQ\u20107 scores and SNOT\u201022 ear subdomain scores is moderately strong, while the correlation between ETDQ\u20107 scores and SNOT\u201022 scores is moderate.
