Patients were grouped by the occurrence of a composite airway event, which included difficult intubation, severe hypoxemia, postoperative airway intervention, or unplanned ICU admission.Univariate and multivariate logistic regression identified independent predictors. A nomogram-based model was developed. Data were split into training and validation sets. Performance was assessed using ROC curves, calibration plots, bootstrap resampling, and decision curve analysis (DCA).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Multivariate analysis identified body weight (OR=1.11), modified Mallampati classification (OR=2.55), and tonsil size grade (OR=3.74) as independent predictors. The model showed excellent discrimination with AUCs of 0.904 (training) and 0.924 (validation). At a cutoff of 0.244, the model showed 83.8% sensitivity and 84.8% specificity in the training set, and 88.9% sensitivity and 91.7% specificity in the validation set, with negative predictive values of 94.1% and 98.2%, respectively. High-risk patients had a 7.09-fold increased risk (95% CI: 2.35\u201327.04,\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      &lt;0.001).

Its high negative predictive value may be particularly useful for identifying patients at relatively low risk, while high-risk predictions should be interpreted in conjunction with clinical assessment.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/01455613261492353","type":"journal-article","created":{"date-parts":[[2026,9,23]],"date-time":"2026-09-23T13:52:16Z","timestamp":1790171536000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":1,"title":["Preoperative Risk Stratification for Major Perioperative Airway Events in Adult Tonsillectomy: A Retrospective Cohort Study"],"prefix":"10.1177","author":[{"given":"Rexidanmu","family":"Hudabai","sequence":"first","affiliation":[{"name":"The Fifth Affiliated Hospital of Sun Yat-Sen University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shuwen","family":"Tang","sequence":"additional","affiliation":[{"name":"The Fifth Affiliated Hospital of Sun Yat-Sen University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Minting","family":"Chen","sequence":"additional","affiliation":[{"name":"The Fifth Affiliated Hospital of Sun Yat-Sen University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Aiqing","family":"Peng","sequence":"additional","affiliation":[{"name":"The Fifth Affiliated Hospital of Sun Yat-Sen University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2018-9544","authenticated-orcid":false,"given":"Xian zhen","family":"Chen","sequence":"additional","affiliation":[{"name":"The Fifth Affiliated Hospital of Sun Yat-Sen University"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2026,9,23]]},"reference":[{"key":"e_1_3_7_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.amjoto.2022.103403"},{"key":"e_1_3_7_3_2","doi-asserted-by":"publisher","DOI":"10.3122\/jabfm.2020.06.200038"},{"key":"e_1_3_7_4_2","doi-asserted-by":"publisher","DOI":"10.1177\/03000605221112369"},{"key":"e_1_3_7_5_2","doi-asserted-by":"publisher","DOI":"10.1001\/jamaoto.2013.6215"},{"key":"e_1_3_7_6_2","doi-asserted-by":"publisher","DOI":"10.17245\/jdapm.2023.23.4.179"},{"key":"e_1_3_7_7_2","doi-asserted-by":"publisher","DOI":"10.1111\/anae.15299"},{"key":"e_1_3_7_8_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijporl.2011.07.034"},{"key":"e_1_3_7_9_2","doi-asserted-by":"publisher","DOI":"10.1097\/ACO.0000000000001125"},{"key":"e_1_3_7_10_2","doi-asserted-by":"publisher","DOI":"10.1213\/ANE.0000000000005444"},{"key":"e_1_3_7_11_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijporl.2025.112327"},{"key":"e_1_3_7_12_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1460-9592.2008.02860.x"},{"key":"e_1_3_7_13_2","doi-asserted-by":"publisher","DOI":"10.4274\/tao.2024.2023-10-2"},{"key":"e_1_3_7_14_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jclinane.2021.110306"},{"key":"e_1_3_7_15_2","doi-asserted-by":"publisher","DOI":"10.11152\/mu-1764"},{"key":"e_1_3_7_16_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.wneu.2024.04.156"},{"key":"e_1_3_7_17_2","doi-asserted-by":"publisher","DOI":"10.1213\/ANE.0000000000001416"},{"key":"e_1_3_7_18_2","doi-asserted-by":"publisher","DOI":"10.1213\/ANE.0000000000003434"},{"key":"e_1_3_7_19_2","doi-asserted-by":"publisher","DOI":"10.1186\/s12871-024-02627-1"},{"key":"e_1_3_7_20_2","doi-asserted-by":"publisher","DOI":"10.1007\/s12630-021-02008-z"},{"key":"e_1_3_7_21_2","doi-asserted-by":"publisher","DOI":"10.4103\/0019-5049.199855"},{"issue":"9","key":"e_1_3_7_22_2","first-page":"2305","article-title":"PREDICTION OF DIFFICULT INTUBATION BY USING UPPER LIP BITE, THYROMENTAL DISTANCE AND MALLAMPATI SCORE IN COMPARISON TO CORMACK AND LEHANE CLASSIFICATION SYSTEM","volume":"74","author":"As D","year":"1960","unstructured":"As D, Bz T, Is S.
