Validation testing was performed in a cadaveric model. Optimal exposure of the cadaveric larynx and supraglottis was determined by ensuring the endoscope tip was exactly 2.5\u2009cm from the level of the vocal cords. The prototype exposure (22\u2010cm adjustable tip laryngoscope) was compared to the Weerda (18\u2010cm distending laryngoscope) and Dedo (18\u2010cm operating laryngoscope) laryngoscope exposures. Anteroposterior (AP) and lateral (L) exposure measurements were obtained from analysis of endoscopic images. Objective millimeter quantification was performed by pixel calibration to the known width of the vocal cord.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The prototype provided 77.3\u2010mm AP and 40.6\u2010mm L exposure of the cadaveric larynx and supraglottis. These measurements were then compared to the exposure provided by the Weerda (49.9\u2010mm AP, 40.4\u2010mm L) and Dedo (15.7\u2010mm AP, 18.6\u2010mm L) laryngoscopes. The investigators found the prototype had similar handling characteristics to the Weerda laryngoscope and laryngeal instrumentation was enhanced due to a wider field of view.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>This novel laryngoscope with an adjustable distal tip provides improved exposure of the supraglottis and glottis in a cadaveric study and has the potential to be used for both supraglottic\/glottic and proximal esophageal procedures.<\/jats:p><\/jats:sec><jats:sec><jats:title>Level of Evidence<\/jats:title><jats:p>5 <jats:italic>Laryngoscope<\/jats:italic>, 2020<\/jats:p><\/jats:sec>","DOI":"10.1002\/lary.28605","type":"journal-article","created":{"date-parts":[[2020,3,16]],"date-time":"2020-03-16T14:13:30Z","timestamp":1584368010000},"page":"2859-2862","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["A Novel Laryngoscope With an Adjustable Distal Tip"],"prefix":"10.1002","volume":"130","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5697-7588","authenticated-orcid":false,"given":"Adam","family":"Honeybrook","sequence":"first","affiliation":[{"name":"Department of Otorhinolaryngology\u2013Head and Neck Surgery University of Pennsylvania  Philadelphia Pennsylvania U.S.A."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Walter","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Head and Neck Surgery &amp; Communication Sciences, Duke University  Durham North Carolina U.S.A."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7965-604X","authenticated-orcid":false,"given":"Seth","family":"Cohen","sequence":"additional","affiliation":[{"name":"Department of Head and Neck Surgery &amp; Communication Sciences, Duke University  Durham North Carolina U.S.A."}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2020,3,16]]},"reference":[{"key":"e_1_2_6_2_1","doi-asserted-by":"publisher","DOI":"10.1177\/0003489414522967"},{"key":"e_1_2_6_3_1","doi-asserted-by":"publisher","DOI":"10.1097\/00000539-199606000-00017"},{"key":"e_1_2_6_4_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00405-008-0853-z"},{"key":"e_1_2_6_5_1","doi-asserted-by":"publisher","DOI":"10.1177\/000348940511400806"},{"key":"e_1_2_6_6_1","doi-asserted-by":"publisher","DOI":"10.1007\/BF03009858"},{"key":"e_1_2_6_7_1","doi-asserted-by":"publisher","DOI":"10.1213\/ane.0b013e31818fc347"},{"key":"e_1_2_6_8_1","doi-asserted-by":"publisher","DOI":"10.1002\/lary.1983.93.5.639"},{"key":"e_1_2_6_9_1","first-page":"58","article-title":"A new laryngoscope for endolaryngeal microsurgery.
