Data was collected on demographics, PSG parameters, and surgical management. Statistical comparisons between groups for the prevalence of pOSA were performed with the \u03c72 test or Fisher's exact test, for PSG parameters prior to AT with Student's <jats:italic>t<\/jats:italic>\u2010test or Mann\u2013Whitney Rank Sum Test, and for PSG parameters before and after AT with paired t\u2010test and Wilcoxon Signed Rank Test. <jats:italic>p<\/jats:italic>\u2009&lt;\u20090.05 was considered significant.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Of the 1167 children (682 male, 485 female, median age\u2009=\u20095.7\u2009years), 321 (28%) had pOSA. POSA children (median age\u2009=\u20097.4\u2009years) were older than children with no pOSA (median\u2009=\u20095.2) (<jats:italic>p<\/jats:italic>\u2009\u2264\u20090.001). The prevalence of pOSA in the subgroups of gender and weight was not different. The prevalence of pOSA was significantly different amongst the race groups (<jats:italic>p<\/jats:italic>\u2009=\u20090.005). Compared with the Black\/African American race, the white race had 1.4 times the odds of pOSA (95% CI, 1.07\u20131.98). The prevalence of pOSA was not significantly different between mild, moderate, and severe OSA groups (<jats:italic>p<\/jats:italic>\u2009=\u20090.7). Of the 66 POSA children who had PSG pre\u2010 and post\u2010TA, 50 (76%) had resolution of pOSA. Children older than 6\u2009years of age and children with obesity had a higher rate of persistent pOSA (<jats:italic>p<\/jats:italic>\u2009=\u20090.02 and <jats:italic>p<\/jats:italic>\u2009=\u20090.008, respectively).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>POSA occurred frequently in OSA children undergoing AT. POSA is resolved in the majority of children after AT. Persistent pOSA was more prevalent in older and obese children. AT is used as the first\u2010line treatment for pOSA in children. Future studies are needed to determine the role of positional therapy and other OSA therapies in the management of persistent pOSA after AT.<\/jats:p><\/jats:sec><jats:sec><jats:title>Level of Evidence<\/jats:title><jats:p>4.<\/jats:p><\/jats:sec>","DOI":"10.1002\/lio2.70116","type":"journal-article","created":{"date-parts":[[2025,3,11]],"date-time":"2025-03-11T21:08:16Z","timestamp":1741727296000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Assessment of Positional Obstructive Sleep Apnea in Children Undergoing Adenotonsillectomy for Obstructive Sleep Apnea"],"prefix":"10.1002","volume":"10","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0503-7051","authenticated-orcid":false,"given":"Seckin O.","family":"Ulualp","sequence":"first","affiliation":[{"name":"Department of Otolaryngology\u2010Head and Neck Surgery University of Texas Southwestern Medical Center and Division of Pediatric Otolaryngology, Children's Medical Center  Dallas Texas USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2322-5347","authenticated-orcid":false,"given":"Romaine F.","family":"Johnson","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology\u2010Head and Neck Surgery University of Texas Southwestern Medical Center and Division of Pediatric Otolaryngology, Children's Medical Center  Dallas Texas USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7890-0541","authenticated-orcid":false,"given":"Ron B.","family":"Mitchell","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology\u2010Head and Neck Surgery University of Texas Southwestern Medical Center and Division of Pediatric Otolaryngology, Children's Medical Center  Dallas Texas USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2025,3,4]]},"reference":[{"key":"e_1_2_8_2_1","doi-asserted-by":"publisher","DOI":"10.1164\/ajrccm.153.2.8564147"},{"key":"e_1_2_8_3_1","doi-asserted-by":"publisher","DOI":"10.1093\/sleep\/32.6.731"},{"key":"e_1_2_8_4_1","doi-asserted-by":"publisher","DOI":"10.1136\/thx.2010.134858"},{"key":"e_1_2_8_5_1","doi-asserted-by":"publisher","DOI":"10.1542\/peds.111.3.554"},{"key":"e_1_2_8_6_1","doi-asserted-by":"publisher","DOI":"10.1002\/ppul.1950160208"},{"issue":"176","key":"e_1_2_8_7_1","first-page":"3","article-title":"Evaluation of Pulmonary Function and Polysomnography in Obese Children and Adolescents","volume":"21","author":"Marcus C.
