This prospective, case\u2010control study aimed to compare soft palate dimensions, nasopharyngeal cross\u2010sectional area (CSA), and nasopharyngeal collapsibility at various locations in non\u2010brachycephalic dogs with and without stertor. A total of 50 dogs were recruited and stratified into control (<jats:italic>n\u00a0<\/jats:italic>=\u00a034) and stertor (<jats:italic>n\u00a0<\/jats:italic>=\u00a013) groups. Static and dynamic computed tomography was conducted without tracheal intubation, and the following variables were calculated: normalized soft palate length and thickness, normalized maximum and minimum nasopharyngeal CSAs (rCSAmax and rCSAmin), and nasopharyngeal collapsibility at the level of the cranial end of the soft palate, pterygoid hamulus, foramen lacerum, bony labyrinth, and caudal end of the soft palate. The stertor group demonstrated significantly lower rCSAmax and rCSAmin, as well as higher nasopharyngeal collapsibility compared with the control group, while no significant differences were noted in the soft palate dimension. Evaluating nasopharyngeal collapse at the foramen lacerum level was recommended due to the clear presence of identifiable bony landmarks and lower overlap in the nasopharyngeal collapsibility between dogs with and without stertor. Physical dimensions of the soft palate may not be the primary contributing factor to nasopharyngeal collapse and clinical signs in non\u2010brachycephalic dogs.<\/jats:p>","DOI":"10.1111\/vru.13371","type":"journal-article","created":{"date-parts":[[2024,4,12]],"date-time":"2024-04-12T18:59:22Z","timestamp":1712948362000},"page":"369-376","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Non\u2010brachycephalic dogs with stertor have higher nasopharyngeal collapsibility compared with dogs without stertor and foramen lacerum level is ideal for evaluating nasopharyngeal collapse on dynamic CT"],"prefix":"10.1111","volume":"65","author":[{"given":"Daji","family":"Noh","sequence":"first","affiliation":[{"name":"College of Veterinary Medicine Kyungpook National University  Daegu South Korea"},{"name":"24 Africa Animal Medical Center  Daejeon South Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hyun\u2010guk","family":"Shin","sequence":"additional","affiliation":[{"name":"24 Africa Animal Medical Center  Daejeon South Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hojung","family":"Choi","sequence":"additional","affiliation":[{"name":"College of Veterinary Medicine Chungnam National University  Daejeon South Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3207-0989","authenticated-orcid":false,"given":"Youngwon","family":"Lee","sequence":"additional","affiliation":[{"name":"College of Veterinary Medicine Chungnam National University  Daejeon South Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4649-809X","authenticated-orcid":false,"given":"Kija","family":"Lee","sequence":"additional","affiliation":[{"name":"College of Veterinary Medicine Kyungpook National University  Daegu South Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2024,4,12]]},"reference":[{"key":"e_1_2_11_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.prrv.2015.10.003"},{"key":"e_1_2_11_3_1","doi-asserted-by":"publisher","DOI":"10.1136\/vr.k1403"},{"key":"e_1_2_11_4_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1748\u20105827.2011.01047.x"},{"key":"e_1_2_11_5_1","doi-asserted-by":"publisher","DOI":"10.1111\/vsu.12418"},{"key":"e_1_2_11_6_1","doi-asserted-by":"publisher","DOI":"10.1111\/vru.12655"},{"key":"e_1_2_11_7_1","doi-asserted-by":"publisher","DOI":"10.1111\/vsu.13302"},{"key":"e_1_2_11_8_1","doi-asserted-by":"publisher","DOI":"10.1111\/jvim.12598"},{"key":"e_1_2_11_9_1","doi-asserted-by":"publisher","DOI":"10.1292\/jvms.21\u20100216"},{"key":"e_1_2_11_10_1","doi-asserted-by":"publisher","DOI":"10.5664\/jcsm.6444"},{"key":"e_1_2_11_11_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jpedsurg.2014.08.021"},{"key":"e_1_2_11_12_1","doi-asserted-by":"publisher","DOI":"10.1152\/jappl.1993.74.4.1504"},{"key":"e_1_2_11_13_1","doi-asserted-by":"publisher","DOI":"10.1378\/chest.06\u20102653"},{"key":"e_1_2_11_14_1","first-page":"86","volume-title":"Miller's Anatomy of the Dog","author":"Evans HE","year":"2013"},{"key":"e_1_2_11_15_1","doi-asserted-by":"publisher","DOI":"10.1292\/jvms.19\u20100515"},{"key":"e_1_2_11_16_1","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0196959"},{"key":"e_1_2_11_17_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1748\u20105827.1989.tb01531.x"},{"key":"e_1_2_11_18_1","doi-asserted-by":"publisher","DOI":"10.1002\/ar.21417"},{"key":"e_1_2_11_19_1","doi-asserted-by":"publisher","DOI":"10.1001\/archoto.2008.538"},{"key":"e_1_2_11_20_1","doi-asserted-by":"publisher","DOI":"10.1098\/rsos.160254"},{"key":"e_1_2_11_21_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.wjorl.2017.05.002"},{"key":"e_1_2_11_22_1","doi-asserted-by":"publisher","DOI":"10.1111\/jsap.12909"},{"key":"e_1_2_11_23_1","doi-asserted-by":"publisher","DOI":"10.2460\/javma.230.12.1870"},{"key":"e_1_2_11_24_1","doi-asserted-by":"publisher","DOI":"10.1111\/jvim.13612"},{"key":"e_1_2_11_25_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.cvsm.2013.09.004"},{"key":"e_1_2_11_26_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1939\u20101676.2012.00887.x"},{"key":"e_1_2_11_27_1","doi-asserted-by":"publisher","DOI":"10.1113\/jphysiol.2011.213157"},{"key":"e_1_2_11_28_1","doi-asserted-by":"publisher","DOI":"10.3238\/arztebl.2016.0463"}],"container-title":["Veterinary Radiology &amp;
