This study aimed to evaluate whether preoperative polysomnographic (PSG) parameters, along with drug\u2010induced sleep endoscopy (DISE) findings, can predict surgical outcomes in patients with OSA.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>This retrospective study included 56 adult patients with OSA who completed both pre\u2010 and postoperative PSG and DISE assessments. Patients were classified into a successful outcome group (SG; \u2265\u200920\u2009events\/h reduction in apnea\u2013hypopnea index [AHI]) or a worse outcome group (WG; \u2265\u200920\u2009events\/h increase in AHI). Baseline PSG and DISE findings were compared between groups, and multivariate regression analysis was used to identify independent predictors of surgical success.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Patients in the SG exhibited significantly higher preoperative AHI and larger tonsil size compared to those in the WG. While DISE collapse patterns did not differ significantly between groups, key differences emerged in PSG metrics. SG patients had a significantly greater proportion of non\u2010REM stage N3 sleep within non\u2010REM sleep and a lower arousal index, both of which were independently associated with improved surgical outcomes. Additionally, respiratory events were more prominent during non\u2010rapid eye movement sleep in SG patients. Multivariate analysis confirmed that a greater proportion of non\u2010REM stage N3 sleep and lower arousal index were strong predictors of postoperative AHI reduction.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>These findings may offer more reliable predictors of which OSA patients will benefit from sleep surgery and underscore the importance of incorporating detailed PSG analysis into preoperative evaluations.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Level of Evidence<\/jats:title>\n                    <jats:p>4.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1002\/lio2.70331","type":"journal-article","created":{"date-parts":[[2025,12,18]],"date-time":"2025-12-18T12:47:02Z","timestamp":1766062022000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Predictive Value of Sleep Architecture and Arousal Index for Surgical Outcomes in Obstructive Sleep Apnea"],"prefix":"10.1002","volume":"10","author":[{"given":"Dong Yun","family":"Lee","sequence":"first","affiliation":[{"name":"Department of Otorhinolaryngology\u2010Head and Neck Surgery Soonchunhyang University College of Medicine  Seoul Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hyun Jung","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology\u2010Head and Neck Surgery Gyeongsang National University Hospital  Changwon Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5905-057X","authenticated-orcid":false,"given":"Jayoung","family":"Oh","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology\u2010Head and Neck Surgery Seoul National University Bundang Hospital  Seongnam Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6358-8900","authenticated-orcid":false,"given":"Siyeon","family":"Jin","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology\u2010Head and Neck Surgery Seoul National University Hospital  Seoul Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9999-0910","authenticated-orcid":false,"given":"Dongyoung","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology\u2010Head and Neck Surgery Seoul National University Hospital  Seoul Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Doo Hee","family":"Han","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology\u2010Head and Neck Surgery Seoul National University Hospital  Seoul Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hyun Jik","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology\u2010Head and Neck Surgery Seoul National University Hospital  Seoul Korea"},{"name":"Sensory Organ Research Institute Seoul National University Medical Research Center  Seoul Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2025,12,18]]},"reference":[{"key":"e_1_2_9_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/S2213-2600(19)30198-5"},{"key":"e_1_2_9_3_1","article-title":"Continuous Positive Airways Pressure for Obstructive Sleep Apnoea in Adults","volume":"19","author":"Giles T.
