Adherence to the olfactory training regimen is, however, generally\nlow. We aimed to investigate if a new form of odor delivery, using scented nasal inserts, could enhance adherence to olfactory\ntraining by allowing participants to be mobile during the training and thereby lower the perceived intrusion on everyday life.\nMethods: Using a randomized controlled parallel-group design, individuals (N = 116) with hyposmia underwent 8 weeks of olfactory\ntraining. One group was assigned olfactory training using scented nasal inserts (nasal devices that retain nasal patency) while\nthe other group was assigned the standard care regimen currently recommended by the Swedish healthcare system. We assessed\nobjective and subjective olfactory ability before and after olfactory training as well as adherence to training.\nResults: Both groups significantly improved both their objective and subjective olfactory abilities, and training with nasal inserts\nproduced similar improvement as standard care in overall treatment outcome. However, there was a significantly greater increase\nin discrimination performance and lower dropout rate (6.7%) in the nasal insert compared to the standard care group (23.2%).\nCritically, after exclusion of the drop-out participants, the nasal insert group still showed significantly higher adherence to the\ntraining regimen.\nConclusions: Olfactory training with nasal inserts could serve as a more effective form of treatment for hyposmia due to patients'\nimproved adherence to protocol and increased tendency to finish their treatment regimen.<\/jats:p>","DOI":"10.4193\/rhin24.369","type":"journal-article","created":{"date-parts":[[2025,4,25]],"date-time":"2025-04-25T11:05:28Z","timestamp":1745579128000},"page":"0-0","source":"Crossref","is-referenced-by-count":4,"title":["Olfactory training using nasal inserts is more effective due to increased adherence"],"prefix":"10.4193","volume":"0","author":[{"given":"A L","family":"Winter","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"S","family":"Heneke","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"E","family":"Thunell","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M","family":"Swartz","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J","family":"Martinsen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"P","family":"Sahlstrand Johnson","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J N","family":"Lundstr\u00f6m","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"2708","published-online":{"date-parts":[[2025,4,1]]},"container-title":["Rhinology Journal"],"original-title":[],"deposited":{"date-parts":[[2025,7,7]],"date-time":"2025-07-07T08:12:14Z","timestamp":1751875934000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.rhinologyjournal.com\/Abstract.php?id=3285"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,4,1]]},"references-count":0,"journal-issue":{"issue":"0","published-online":{"date-parts":[[2025,4,1]]}},"URL":"https:\/\/doi.org\/10.4193\/rhin24.369","relation":{"has-preprint":[{"id-type":"doi","id":"10.1101\/2024.06.26.24309521","asserted-by":"object"}]},"ISSN":["0300-0729"],"issn-type":[{"value":"0300-0729","type":"print"}],"subject":[],"published":{"date-parts":[[2025,4,1]]}}}
