Objective: To identify clinical, polysomnographic, and baseline DISE anatomic factors associated with jaw-thrust responsiveness. Methods: We conducted a single-center retrospective observational study of adults with polysomnography-confirmed OSA who underwent DISE with paired baseline and jaw-thrust VOTE assessments between 1 January 2015 and 31 December 2025 (n = 355). Jaw-thrust responsiveness was defined a priori as a within-subject reduction in the number of obstructed VOTE sites (grade \u2265 1). Multivariable logistic regression was used to identify independent correlates within a prespecified explanatory modeling framework. The study was approved by the Institutional Review Board of Taipei Tzu Chi Hospital (protocol 14-IRB079), with the need for informed consent being waived. Results: Jaw thrust reduced overall obstruction burden from two (two to three) to one (one to two) sites (Wilcoxon p &lt; 0.001). Hypopharyngeal levels demonstrated the greatest improvement, particularly at the tongue base (39.2% to 7.6%) and epiglottis (23.9% to 5.4%) (both p &lt; 0.001). Overall, 62.8% met responder criteria and 18.9% achieved complete normalization. In multivariable analysis (n = 272), baseline tongue-base collapse (adjusted odds ratio [aOR] 2.46, 95% CI 1.20\u20135.04) and greater baseline multilevel obstruction burden (aOR 1.85 per SD, 95% CI 1.19\u20132.85) were independently associated with responsiveness, whereas conventional PSG severity metrics were not. Conclusions: In adults with OSA, jaw-thrust responsiveness during DISE is more strongly associated with baseline anatomic phenotype than with global PSG severity. Standardized DISE functional assessment may provide complementary information to support phenotype-informed selection of non-CPAP therapies, pending prospective validation.<\/jats:p>","DOI":"10.3390\/life16030456","type":"journal-article","created":{"date-parts":[[2026,3,11]],"date-time":"2026-03-11T09:00:37Z","timestamp":1773219637000},"page":"456","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Baseline DISE Anatomy Predicts Jaw-Thrust Responsiveness in Obstructive Sleep Apnea"],"prefix":"10.3390","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0009-0000-8179-0486","authenticated-orcid":false,"given":"Wei-Hung","family":"Chang","sequence":"first","affiliation":[{"name":"Department of Critical Care Medicine, MacKay Memorial Hospital, Taipei 10449, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0276-1500","authenticated-orcid":false,"given":"Kuan-Pen","family":"Yu","sequence":"additional","affiliation":[{"name":"Department of Critical Care Medicine, MacKay Memorial Hospital, Taipei 10449, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Li-Kuo","family":"Kuo","sequence":"additional","affiliation":[{"name":"Department of Critical Care Medicine, MacKay Memorial Hospital, Taipei 10449, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chung","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Medicine, Taipei Tzu Chi Hospital, Buddhist Tzu Chi Medical Foundation, Taipei 10412, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2026,3,11]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"70","DOI":"10.1016\/j.smrv.2016.07.002","article-title":"Prevalence of obstructive sleep apnea in the general population: A systematic review","volume":"34","author":"Senaratna","year":"2017","journal-title":"Sleep Med.
