The objective of this study was to evaluate the nasal patency after nose-blowing by pinching the nose versus no pinching. The patients who have nasal discharge such as allergic rhinitis or common cold were recruited. The patients were randomized to perform pinching or no pinching nose-blowing. Fifty patients were enrolled in this study. The objective evaluation using acoustic rhinometry found no difference in nasal patency between the two groups (p\u2009&gt;\u20090.05). The subjective patency score was significantly higher in the pinch one nostril shut group (mean difference 0.88, 95% CI 0.20\u20131.55). The patency of the two methods were comparable according to the objective test. However, the patients felt that their nose was clearer when pinching and blowing.<\/jats:p>","DOI":"10.1038\/s41598-021-01631-6","type":"journal-article","created":{"date-parts":[[2021,11,11]],"date-time":"2021-11-11T06:06:09Z","timestamp":1636610769000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Comparison of nasal patency after nose-blowing between pinch versus no pinch method: a randomized controlled trial"],"prefix":"10.1038","volume":"11","author":[{"given":"Patorn","family":"Piromchai","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jakkrit","family":"Netnoi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Supaporn","family":"Srirompotong","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Panida","family":"Thanawirattananit","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2021,11,11]]},"reference":[{"key":"1631_CR1","doi-asserted-by":"publisher","first-page":"15665","DOI":"10.1038\/s41598-020-72798-7","volume":"10","author":"S Asadi","year":"2020","unstructured":"Asadi, S. et al.
