Thus, the aim of this study is to analyze spatial changes in the normal oropharynx during respiration and mastication. For this purpose, eight 7\u20138\u2009months old Yucatan minipigs, four of each sex were used. X\u2010ray fluoroscopy was recorded with the field of view focused on the oropharyngeal region. The x\u2010ray video clips showing respiratory cycles and masticatory sequences were digitized and traced. Points to be digitized and traced were located on the soft palate, epiglottis, tongue base, and pharyngeal wall.

In contrast, distance changes in the tongue base were significantly smaller (0.32\u2009\u00b1\u20090.21\u2009mm,\n                    <jats:italic>p<\/jats:italic>\n                    \u2009&lt;\u20090.05). Notably, during chewing the tongue base and epiglottis showed major changes in distance and direction. Similarly, during swallowing the tongue base showed the largest changes (2.94\u2009\u00b1\u20091.28\u2009mm) followed by the pharyngeal wall and epiglottis. Thus, although coordinated, each pharyngeal structure plays specific roles. Understanding of these spatial and specific dynamics in different oropharyngeal structures would provide the baseline to analyze the potential mechanisms of various swallowing and breathing disorders such as dysphagia and obstructive sleep apnea.\n                  <\/jats:p>","DOI":"10.1002\/ar.25605","type":"journal-article","created":{"date-parts":[[2024,12,2]],"date-time":"2024-12-02T05:59:13Z","timestamp":1733119153000},"page":"2507-2518","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Spatial relationships of oropharyngeal structures during respiration, chewing, and swallowing"],"prefix":"10.1002","volume":"309","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8008-9281","authenticated-orcid":false,"given":"Doris Haydee","family":"Rosero Salazar","sequence":"first","affiliation":[{"name":"Department of Orthodontics University of Washington  Seattle Washington USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lucas","family":"Honnlee","sequence":"additional","affiliation":[{"name":"Department of Orthodontics University of Washington  Seattle Washington USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Phuc Hoang","family":"Nguyen","sequence":"additional","affiliation":[{"name":"Department of Orthodontics University of Washington  Seattle Washington USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Elliot","family":"Willis","sequence":"additional","affiliation":[{"name":"Department of Orthodontics University of Washington  Seattle Washington USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8233-5861","authenticated-orcid":false,"given":"Zi\u2010Jun","family":"Liu","sequence":"additional","affiliation":[{"name":"Department of Orthodontics University of Washington  Seattle Washington USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2024,12,2]]},"reference":[{"key":"e_1_2_10_2_1","article-title":"The anatomical relationships of the tongue with the body system","volume":"10","author":"Bordoni B.","year":"2018","journal-title":"Cureus"},{"key":"e_1_2_10_3_1","first-page":"334","article-title":"Reduced coordination of hyolaryngeal elevation and bolus movement in a pig model of preterm infant swallowing","volume":"35","author":"Catchpole E.","year":"2020","journal-title":"Dysoft Palatehagia"},{"key":"e_1_2_10_4_1","doi-asserted-by":"publisher","DOI":"10.1113\/jphysiol.2008.156430"},{"key":"e_1_2_10_5_1","doi-asserted-by":"publisher","DOI":"10.15761\/jts.1000374"},{"key":"e_1_2_10_6_1","doi-asserted-by":"publisher","DOI":"10.2214\/ajr.154.5.2108570"},{"key":"e_1_2_10_7_1","first-page":"51","article-title":"LVC timing in infant pig swallowing and the effect of safe swallowing","volume":"33","author":"Gross A.","year":"2018","journal-title":"Dysoft Palatehagia"},{"key":"e_1_2_10_8_1","doi-asserted-by":"publisher","DOI":"10.3389\/fphys.2021.696071"},{"key":"e_1_2_10_9_1","volume-title":"Anatomy, head and neck, palate","author":"Helwany M.","year":"2023"},{"key":"e_1_2_10_10_1","doi-asserted-by":"publisher","DOI":"10.1201\/b11356-40"},{"key":"e_1_2_10_11_1","first-page":"31","article-title":"Food transoft palateort and bolus formation during complete feeding sequences on foods of different initial consistency","volume":"14","author":"Hiiemae K.
