The duration of nasal polyposis and nasal surgery may also affect olfaction. It has been shown that aging and chronic rhinitis both impair olfaction. The aim of our study was to evaluate the sense of smell in patients who had had nasal polyposis for at least 20 years. The olfactory threshold was assessed with a commercially available odor detection threshold test. The threshold of 19 (46%) of 41 patients was greater than the age-related upper 95% reference limit. In a forward stepwise multiple regression analysis of all the polyposis patients, the degree of opacity of ethmoidal sinuses seen in computed tomography (CT), polyposis visible in anterior rhinoscopy, total nasal resistance, and gender had a significant association with olfactory threshold.<\/jats:p>","DOI":"10.2500\/105065801779954229","type":"journal-article","created":{"date-parts":[[2007,2,23]],"date-time":"2007-02-23T06:00:34Z","timestamp":1172210434000},"page":"159-164","source":"Crossref","is-referenced-by-count":31,"title":["Sense of Smell in Long-Standing Nasal Polyposis"],"prefix":"10.1177","volume":"15","author":[{"given":"Seija I.","family":"Vento","sequence":"first","affiliation":[{"name":"Department of Otorhinolaryngology, Helsinki University Central Hospital, Helsinki, Finland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Markku","family":"Simola","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology, Kiljava Hospital, 05250 Kiljava, Finland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Liisa O.","family":"Ertama","sequence":"additional","affiliation":[{"name":"Department of Radiology, Kuusankoski District Hospital, 45750 Sairaalam\u00e4ki, Finland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"C.
