We utilize structure from motion (SfM) photogrammetry, to reconstruct 3D surfaces of pathologic and healthy pediatric larynges from monocular two\u2010dimensional (2D) endoscopy. Models of pediatric subglottic stenosis were 3D printed and airway endoscopies were simulated. 3D surfaces were successfully reconstructed from endoscopic videos of all models using an SfM analysis toolkit. Average subglottic surface error between SfM reconstructed surfaces and 3D printed models was 0.65\u2009mm as measured by Modified Hausdorff Distance. Average volumetric similarity between SfM surfaces and printed models was 0.82 as measured by Jaccard Index. SfM can be used to accurately reconstruct 3D surface renderings of the larynx from 2D endoscopy video. This technique has immense potential for use in quantitative analysis of airway geometry and virtual surgical planning.<\/jats:p>","DOI":"10.1002\/ohn.635","type":"journal-article","created":{"date-parts":[[2024,1,3]],"date-time":"2024-01-03T05:19:45Z","timestamp":1704259185000},"page":"1195-1199","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Surface Reconstruction of the Pediatric Larynx via Structure from Motion Photogrammetry: A Pilot Study"],"prefix":"10.1002","volume":"170","author":[{"given":"Michael C.","family":"Barbour","sequence":"first","affiliation":[{"name":"Department of Mechanical Engineering University of Washington Seattle Washington USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7947-4724","authenticated-orcid":false,"given":"Shaunak N.","family":"Amin","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology\u2013Head and Neck Surgery University of Washington Seattle Washington USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Seth D.","family":"Friedman","sequence":"additional","affiliation":[{"name":"Center for Respiratory Biology and Therapeutics Seattle Children's Hospital Seattle Washington USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Francisco A.","family":"Perez","sequence":"additional","affiliation":[{"name":"Department of Pediatric Radiology Seattle Children's Hospital Seattle Washington USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Randall A.","family":"Bly","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology\u2013Head and Neck Surgery University of Washington Seattle Washington USA"},{"name":"Division of Pediatric Otolaryngology\u2013Head and Neck Surgery Seattle Children's Hospital Seattle Washington USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kaalan E.","family":"Johnson","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology\u2013Head and Neck Surgery University of Washington Seattle Washington USA"},{"name":"Division of Pediatric Otolaryngology\u2013Head and Neck Surgery Seattle Children's Hospital Seattle Washington USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sanjay R.","family":"Parikh","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology\u2013Head and Neck Surgery University of Washington Seattle Washington USA"},{"name":"Division of Pediatric Otolaryngology\u2013Head and Neck Surgery Seattle Children's Hospital Seattle Washington USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Clare M.","family":"Richardson","sequence":"additional","affiliation":[{"name":"Division of Pediatric Otolaryngology\u2013Head and Neck Surgery Seattle Children's Hospital Seattle Washington USA"},{"name":"Division of Pediatric Otolaryngology\u2013Head and Neck Surgery Phoenix Children's Hospital Phoenix Arizona USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"John P.","family":"Dahl","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology\u2013Head and Neck Surgery University of Washington Seattle Washington USA"},{"name":"Division of Pediatric Otolaryngology\u2013Head and Neck Surgery Seattle Children's Hospital Seattle Washington USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alberto","family":"Aliseda","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering University of Washington Seattle Washington USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2024,1,3]]},"reference":[{"key":"e_1_2_8_2_1","doi-asserted-by":"crossref","unstructured":"SchonbergerJL FrahmJM.
