The procedure involves drilling of the frontal T (formed by the septum and middle turbinate`s attachment to the skull base) onto the olfactory fossa often with exposure of the first olfactory neuron and may affect olfactory function. This study was performed to assess patients` subjective sense of smell following this procedure. STUDY DESIGN: Prospective study of retrospective data. METHODS: Sixty-eight patients, who underwent modified endoscopic Lothrop by the senior author (PJW) between 2003 and 2008, completed a post-operative questionnaire asking about their perception of olfactory function. All patients had their pre-operative subjective sense of smell documented prior to undergoing surgery. Patient records were reviewed for pertinent medical information such as the presence of asthma, aspirin sensitivity and nasal polyps. RESULTS: This study found that the majority of patients reported improvement in their sense of smell post-operatively, while only a small number reported a negative impact on their smell. Thirty-nine patients reported an improvement in their post-operative smell grade. Twenty patients reported no change in their smell grade, while the remaining 9 patients stated that their sense of smell worsened after surgery. No statistically significant correlation was found between patient outcome and the presence of asthma, nasal polyps, or Samter`s triad. CONCLUSIONS: The Modified endoscopic Lothrop procedure\/Draf 3 had a positive effect on subjective sense of smell post-operatively in this cohort of patients.<\/jats:p>","DOI":"10.4193\/rhino10.248","type":"journal-article","created":{"date-parts":[[2021,5,25]],"date-time":"2021-05-25T15:27:46Z","timestamp":1621956466000},"page":"217-220","source":"Crossref","is-referenced-by-count":11,"title":["Patient-reported olfactory function following endoscopic sinus surgery with modified endoscopic Lothrop procedure \/ Draf 3"],"prefix":"10.4193","volume":"49","author":[{"given":"J.M.","family":"Yip","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"K.A.","family":"Seiberlin","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"P.-J.","family":"Wormald","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"2708","container-title":["Rhinology journal"],"original-title":[],"deposited":{"date-parts":[[2021,5,25]],"date-time":"2021-05-25T15:27:47Z","timestamp":1621956467000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.rhinologyjournal.com\/Abstract.php?id=990"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2011,6,1]]},"references-count":0,"journal-issue":{"issue":"2","published-print":{"date-parts":[[2011,6,1]]}},"URL":"https:\/\/doi.org\/10.4193\/rhino10.248","relation":{},"ISSN":["0300-0729"],"issn-type":[{"value":"0300-0729","type":"print"}],"subject":[],"published":{"date-parts":[[2011,6,1]]}}}
