We hypothesize that patients with CRSwNP can self-assess their sense of smell better using a visual analog scale (VAS) than using smell tests.\nMethods: A controlled cross-sectional study was performed. Adults diagnosed with severe CRSwNP waiting for endoscopic sinus surgery were included. A cohort of healthy controls was also studied. All participants completed the Barcelona Smell Test 24 (BAST-24), the 22-item Sinonasal Outcomes Test 22 (SNOT-22), and a VAS for loss of smell. Patients with CRSwNP underwent blood testing (eosinophil count, total serum IgE), computed tomography (Lund-Mackay Score), and nasal endoscopy.\nResults: The study population comprised 138 patients with severe CRSwNP and 40 controls. The BAST-24 identification score was strongly correlated with the VAS score in the CRSwNP group (p=\u20130.79, P&lt;.001) but not in the control group (p=\u20130.14; P=.39), this difference between groups being statistically significant (P&lt;.001). A significant correlation was found between SNOT-22 item 21 (loss of smell) and BAST-24 identification (p=\u20130.65, P&lt;.001), this difference being statistically significant (Z=\u20132.43; P=.015). The area under the receiver operating curve was 0.85, with 72.5% sensitivity and 93.1% specificity.\nConclusion: This study demonstrates a potential role of the VAS score for the screening of olfactory dysfunction in severe CRSwNP in daily clinical practice.<\/jats:p>","DOI":"10.18176\/jiaci.0937","type":"journal-article","created":{"date-parts":[[2023,9,6]],"date-time":"2023-09-06T13:09:56Z","timestamp":1694005796000},"page":"377-384","source":"Crossref","is-referenced-by-count":21,"title":["Validation of a Visual Analog Scale for Loss of Smell as a Quick Test in Chronic Rhinosinusitis With Nasal Polyps"],"prefix":"10.18176","volume":"34","author":[{"given":"I","family":"Alobid","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"C","family":"Calvo-Henr\u00edquez","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"P","family":"Viveros-D\u00edez","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M","family":"L\u00f3pez-Chac\u00f3n","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"MJ","family":"Rojas-Lechuga","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"C","family":"Langdon","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"C","family":"Marin","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J","family":"Mullol","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"7491","published-online":{"date-parts":[[2024,12,10]]},"container-title":["Journal of Investigational Allergy and Clinical Immunology"],"original-title":["english"],"deposited":{"date-parts":[[2024,12,10]],"date-time":"2024-12-10T11:12:24Z","timestamp":1733829144000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.jiaci.org\/summary\/vol34-issue6-num2971"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2024,12,9]]},"references-count":0,"journal-issue":{"issue":"6","published-online":{"date-parts":[[2024,12,10]]},"published-print":{"date-parts":[[2024,12,9]]}},"URL":"https:\/\/doi.org\/10.18176\/jiaci.0937","relation":{},"ISSN":["1018-9068"],"issn-type":[{"value":"1018-9068","type":"print"}],"subject":[],"published":{"date-parts":[[2024,12,9]]}}}
