Control images were obtained using endotracheal tubes of varying sizes. In vivo images were obtained from various timepoints of a concurrent study on subglottic stenosis. Using a 0\u00b0 rod telescope, an instrument was placed at the level of interest, and a photo was obtained. Three independent and blinded raters then measured the CSA of the narrowest portion of the airway using open source image analysis software.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>Each blinded rater measured the CSA of 79 photos. The t testing to assess for accuracy showed no difference between measured and known CSAs of the control images ( P = .86), with an average error of 1.5% (SD = 5.5%). All intraclass correlation (ICC) values for intrarater agreement showed excellent agreement (ICC &gt; .75). Interrater reliability among all raters in control (ICC = .975; 95% CI, .817-.995) and in vivo (ICC = .846;, 95% CI, .780-.896) images showed excellent agreement.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions:<\/jats:title>\n                    <jats:p>We validate a simple, accurate, and reproducible method of measuring the CSA of the airway that can be used in a clinical or research setting.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/0003489418759361","type":"journal-article","created":{"date-parts":[[2018,2,24]],"date-time":"2018-02-24T05:19:44Z","timestamp":1519449584000},"page":"275-281","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":4,"title":["A Simple Endoscopic Technique for Measuring the Cross-Sectional Area of the Upper Airway in a Rabbit Model"],"prefix":"10.1177","volume":"127","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1859-0913","authenticated-orcid":false,"given":"Paul R.","family":"Wistermayer","sequence":"first","affiliation":[{"name":"Madigan Army Medical Center, Tacoma, Washington, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3146-0275","authenticated-orcid":false,"given":"Wesley R.","family":"McIlwain","sequence":"additional","affiliation":[{"name":"Madigan Army Medical Center, Tacoma, Washington, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nicholas","family":"Ieronimakis","sequence":"additional","affiliation":[{"name":"Madigan Army Medical Center, Tacoma, Washington, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Derek J.","family":"Rogers","sequence":"additional","affiliation":[{"name":"Madigan Army Medical Center, Tacoma, Washington, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2018,2,24]]},"reference":[{"key":"bibr1-0003489418759361","doi-asserted-by":"publisher","DOI":"10.1097\/00005537-200101000-00009"},{"key":"bibr2-0003489418759361","doi-asserted-by":"publisher","DOI":"10.1177\/000348949410300410"},{"key":"bibr3-0003489418759361","doi-asserted-by":"publisher","DOI":"10.1093\/icvts\/ivt015"},{"key":"bibr4-0003489418759361","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijporl.2016.10.004"},{"key":"bibr5-0003489418759361","doi-asserted-by":"publisher","DOI":"10.1001\/jamaoto.2015.29"},{"key":"bibr6-0003489418759361","doi-asserted-by":"publisher","DOI":"10.1177\/0003489416655353"},{"key":"bibr7-0003489418759361","doi-asserted-by":"publisher","DOI":"10.1002\/lary.24046"},{"key":"bibr8-0003489418759361","doi-asserted-by":"publisher","DOI":"10.1155\/2016\/6838697"},{"key":"bibr9-0003489418759361","doi-asserted-by":"publisher","DOI":"10.1002\/lary.23836"},{"key":"bibr10-0003489418759361","doi-asserted-by":"publisher","DOI":"10.1177\/000348940611501004"},{"key":"bibr11-0003489418759361","doi-asserted-by":"publisher","DOI":"10.1111\/j.1460-9592.2008.02533.x"},{"key":"bibr12-0003489418759361","doi-asserted-by":"publisher","DOI":"10.1002\/sim.5466"}],"container-title":["Annals of Otology, Rhinology &amp; Laryngology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/0003489418759361","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/full-xml\/10.1177\/0003489418759361","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/0003489418759361","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,28]],"date-time":"2026-04-28T11:31:56Z","timestamp":1777375916000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.1177\/0003489418759361"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2018,2,24]]},"references-count":12,"journal-issue":{"issue":"4","published-print":{"date-parts":[[2018,4]]}},"alternative-id":["10.1177\/0003489418759361"],"URL":"https:\/\/doi.org\/10.1177\/0003489418759361","relation":{},"ISSN":["0003-4894","1943-572X"],"issn-type":[{"value":"0003-4894","type":"print"},{"value":"1943-572X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2018,2,24]]}}}
