The study enrolled patients (n = 100) who underwent endoscopy for gastroesophageal reflux disease. Patients with laryngopharyngeal reflux (LPR) were identified by Reflux Symptom Index (RSI) and Reflux Finding Score (RFS). Patients were divided into 2 groups: LPR (+) (n = 64) H pylori (+), RSI &gt; 13, RFS &gt; 7; LPR (\u2212) (n = 36) H pylori (+), RSI &lt; 13, RFS &lt; 7. Visual analog scale (VAS), sinonasal outcome test-22 (SNOT-22), peak nasal inspiratory flowmeter (PNIF), mucociliary clearance (MCC), and olfactory tests were used to evaluate the nasal functions. The average VAS for nasal obstruction, PNIF, and MCC did not differ significantly between the LPR (+) and LPR (\u2212) groups ( P &gt; .05). However, the average olfactory test scores were lower in the LPR (+) patients than the LPR (\u2212) patients ( P &lt; .05). Also, the SNOT-22 scores were significantly higher in LPR (+) patients than in LPR (\u2212) ( P &lt; .01). Nasal functions and symptom scores were also evaluated according to the H pylori grading. The PNIF, MCC, SNOT-22, and olfactory test results deteriorated as the gastric mucosal H pylori colonization increased ( P &lt; .05). In conclusion, nasal functions differed between LPR disease and GERD only, while the density of H pylori colonization in the gastric mucosa had an effect on nasal function.<\/jats:p>","DOI":"10.1177\/0145561319840825","type":"journal-article","created":{"date-parts":[[2019,4,25]],"date-time":"2019-04-25T01:44:31Z","timestamp":1556156671000},"page":"346-350","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":4,"title":["The
