Group B dogs (n = 4) had a muscle-sparing laryngoplasty performed with the thyropharyngeus muscle fibers bluntly separated, and the cricoarytenoideus dorsalis muscle spared. Pre- and 24-hour postoperative fluoroscopic swallowing studies were performed and graded. Larynges were harvested after humane euthanasia, and glottic area was measured. Group C dogs (n = 4) acted as controls, with surgical dissection ending lateral to the thyropharyngeus muscle, arytenoid lateralization not performed, and the dogs not euthanized. The study was performed between October 15, 2011 and May 15, 2021.<\/jats:p>\n<\/jats:sec>\n<jats:sec>\n<jats:title>RESULTS<\/jats:title>\n<jats:p>Changes in pharyngeal and upper esophageal sphincter function were not detected in any group. There was no difference in glottic area between treatment groups. Aspiration of liquid was not a consistent finding. Two dogs in each treatment group developed moderate to severe cervical esophageal paresis. This did not occur in control dogs.<\/jats:p>\n<\/jats:sec>\n<jats:sec>\n<jats:title>CLINICAL RELEVANCE<\/jats:title>\n<jats:p>We found no evidence to support our hypothesis that muscle-sparing laryngoplasty results in less severe changes in swallowing function compared to a standard technique. The cervical esophageal paresis identified in both treatment groups could increase the risk of postoperative aspiration pneumonia in dogs treated for laryngeal paralysis via a lateral approach to the larynx. Further study to determine the frequency, cause, and duration of esophageal dysfunction is warranted.<\/jats:p>\n<\/jats:sec>","DOI":"10.2460\/ajvr.22.03.0040","type":"journal-article","created":{"date-parts":[[2022,7,25]],"date-time":"2022-07-25T12:49:19Z","timestamp":1658753359000},"source":"Crossref","is-referenced-by-count":0,"title":["A lateral surgical approach to the larynx may impair cervical esophageal function in dogs"],"prefix":"10.2460","volume":"83","author":[{"given":"Kyle G.","family":"Mathews","sequence":"first","affiliation":[{"name":"Department of Clinical Sciences, College of Veterinary Medicine, North Carolina State University, Raleigh, NC"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"James C.","family":"Brown","sequence":"additional","affiliation":[{"name":"Department of Molecular and Biomedical Sciences, College of Veterinary Medicine, North Carolina State University, Raleigh, NC"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lola C.","family":"Hudson","sequence":"additional","affiliation":[{"name":"Department of Molecular and Biomedical Sciences, College of Veterinary Medicine, North Carolina State University, Raleigh, NC"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Emily H.","family":"Griffith","sequence":"additional","affiliation":[{"name":"Department of Statistics, College of Sciences, North Carolina State University, Raleigh, NC"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alan J.","family":"Bocage","sequence":"additional","affiliation":[{"name":"Department of Molecular and Biomedical Sciences, College of Veterinary Medicine, North Carolina State University, Raleigh, NC"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jonathan A.","family":"Hash","sequence":"additional","affiliation":[{"name":"Department of Clinical Sciences, College of Veterinary Medicine, North Carolina State University, Raleigh, NC"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1272","reference":[{"issue":"8","key":"B1","series-title":"Aust Vet J","first-page":"464","article-title":"A retrospective study of unilateral arytenoid lateralization in the treatment of laryngeal paralysis in 100 dogs (1992\u20132000)","volume":"81","year":"2003","unstructured":"Snelling SR, Edwards GA.
