We hypothesized this method would conceptually provide time resolution for glottic closure events compared with standard (30 frames per second, fps), and enable a means to measure timing, sequence, and duration of laryngeal movements during swallowing not otherwise visualized.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>A total of 14 healthy adults (4 male, 22\u201380\u2009years) participated. We performed laryngeal HSV at 500fps. Measurements included: (i) feasibility and tolerability of the procedure; (ii) identification of a swallowing segment of interest (SOI) for the peak of the swallow; and (iii) description of laryngeal swallowing movements using a GUI.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Fourteen subjects tolerated the procedure without discomfort and swallow images were able to be analyzed in 12. Using our GUI, mean SOI was 260\u2009ms, yielding 130 frames for analysis (compared with seven in standard laryngoscopy). Vocal fold adduction, vocal fold medialization, and anterior\u2013posterior arytenoid compression to the epiglottis prior to whiteout could be identified and sequenced.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Participants tolerated a low position of the endoscope during dry volitional swallows. The output of our GUI demonstrated a novel technique for identifying, describing, and sequencing a swallowing SOI. Future studies should investigate laryngeal closure and arytenoid positioning with a bolus and in a range of ages, genders, and etiologies in both healthy and abnormal populations to better understand swallowing physiology.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Level of Evidence<\/jats:title>\n                    <jats:p>\n                      NA\n                      <jats:italic>Laryngoscope<\/jats:italic>\n                      , 135:1737\u20131743, 2025\n                    <\/jats:p>\n                  <\/jats:sec>","DOI":"10.1002\/lary.31945","type":"journal-article","created":{"date-parts":[[2024,12,11]],"date-time":"2024-12-11T02:57:52Z","timestamp":1733885872000},"page":"1737-1743","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Using High\u2010Speed Videoendoscopy to Analyze Laryngeal Closure Parameters During Normal Swallow"],"prefix":"10.1002","volume":"135","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5503-0325","authenticated-orcid":false,"given":"Rebecca J.","family":"Howell","sequence":"first","affiliation":[{"name":"Department of Otolaryngology\u2010Head and Neck Surgery University of Cincinnati  Cincinnati Ohio U.S.A."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Amna S.","family":"Mira","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology\u2010Head and Neck Surgery University of Cincinnati  Cincinnati Ohio U.S.A."},{"name":"Department of Communication Sciences and Disorders University of Cincinnati  Cincinnati Ohio U.S.A."},{"name":"College of Applied Medical Sciences King Saud Bin Abdulaziz University for Health Sciences  Riyadh Saudi Arabia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andres","family":"Llico","sequence":"additional","affiliation":[{"name":"Department of Biomedical Engineering University of Cincinnati  Cincinnati Ohio U.S.A."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4230-905X","authenticated-orcid":false,"given":"Victoria S.","family":"McKenna","sequence":"additional","affiliation":[{"name":"Department of Communication Sciences and Disorders University of Cincinnati  Cincinnati Ohio U.S.A."},{"name":"School of Communication Sciences and Disorders University of Central Florida  Orlando Florida U.S.A."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2024,12,10]]},"reference":[{"key":"e_1_2_6_2_1","doi-asserted-by":"publisher","DOI":"10.14198\/jhse.2016.111.05"},{"key":"e_1_2_6_3_1","doi-asserted-by":"publisher","DOI":"10.1044\/2015_JSLHR-S-14-0253"},{"key":"e_1_2_6_4_1","doi-asserted-by":"publisher","DOI":"10.1177\/0003489416656205"},{"key":"e_1_2_6_5_1","doi-asserted-by":"publisher","DOI":"10.1044\/2019_JSLHR-S-18-0405"},{"key":"e_1_2_6_6_1","doi-asserted-by":"publisher","DOI":"10.1002\/lary.24742"},{"key":"e_1_2_6_7_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00455-017-9803-5"},{"key":"e_1_2_6_8_1","doi-asserted-by":"publisher","DOI":"10.1044\/1058-0360.0603.66"},{"key":"e_1_2_6_9_1","doi-asserted-by":"publisher","DOI":"10.1177\/000348940811701210"},{"key":"e_1_2_6_10_1","unstructured":"McKennaVS LlicoAF HowellRJ.Vocal fold kinematics for volitional and reflexive cough in healthy adults using high\u2010speed flexible laryngoscopy.
