Evaluators, blinded to each other's results, reviewed CT images and measured esophageal area at the level of the rima glottidis. For each dog, the left esophageal percentage (LEP) was calculated as the esophageal area left of the rima glottidis midline divided by the overall esophageal area at that level. Variables (age, sex, patient position, intubation status, and maxillary support during CT) were evaluated for association with LEP. The CT images of dogs that had multiple scans were assessed for within-patient variance.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"s004\">\n<jats:title>RESULTS<\/jats:title>\n<jats:p>Mean LEP was 56.2 \u00b1 18.1% for all dogs. Only right lateral recumbency was significantly associated with LEP, with a lower LEP for dogs positioned in right lateral recumbency (42.4 \u00b1 12.7%), compared with left lateral (63.0 \u00b1 7.4%) or sternal (57.3 \u00b1 18.8%) recumbency. No association was detected between LEP and other variables assessed. Eleven dogs had multiple CT scans; within-patient variance for LEP was \u00b1 26.6%.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"s005\">\n<jats:title>CONCLUSIONS AND CLINICAL RELEVANCE<\/jats:title>\n<jats:p>Results indicated that, although most dogs had an LEP &gt; 50%, the esophageal ostium was fairly centrally located in most dogs and may be more mobile than previously thought. Additional research is warranted to assess this mobility and whether the esophageal ostium location, relative to the larynx, affects the incidence of aspiration pneumonia in dogs undergoing surgical treatment for geriatric-onset laryngeal paralysis and polyneuropathy.<\/jats:p>\n<\/jats:sec>","DOI":"10.2460\/ajvr.20.11.0201","type":"journal-article","created":{"date-parts":[[2021,11,3]],"date-time":"2021-11-03T18:21:54Z","timestamp":1635963714000},"page":"975-980","source":"Crossref","is-referenced-by-count":0,"title":["Anatomic characterization of the location of the esophageal ostium relative to the rima glottidis on CT in adult Labrador Retrievers"],"prefix":"10.2460","volume":"82","author":[{"given":"Grace P.","family":"Lai","sequence":"first","affiliation":[{"name":"From the Department of Small Animal Medicine and Surgery, College of Veterinary Medicine, University of Georgia, Athens, GA 30602"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Janet A.","family":"Grimes","sequence":"additional","affiliation":[{"name":"From the Department of Small Animal Medicine and Surgery, College of Veterinary Medicine, University of Georgia, Athens, GA 30602"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mandy L.","family":"Wallace","sequence":"additional","affiliation":[{"name":"From the Department of Small Animal Medicine and Surgery, College of Veterinary Medicine, University of Georgia, Athens, GA 30602"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chad W.","family":"Schmiedt","sequence":"additional","affiliation":[{"name":"From the Department of Small Animal Medicine and Surgery, College of Veterinary Medicine, University of Georgia, Athens, GA 30602"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mason Y.","family":"Savage","sequence":"additional","affiliation":[{"name":"Idexx Laboratories Inc, Westbrook, ME 04092."}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1272","reference":[{"issue":"2","key":"ref1","series-title":"Vet Clin North Am Small Anim Pract","doi-asserted-by":"publisher","first-page":"295","DOI":"10.1016\/j.cvsm.2019.11.001","article-title":"Laryngeal disease in dogs and cats: an update","volume":"50","author":"MacPhail CM","year":"2020","unstructured":"MacPhail CM.
