While mechanical pressure from the endotracheal tube is implicated, quantitative data linking tube-tissue contact pressure to POLPD are lacking. This study aimed to establish a quantitative relationship between tracheal tube contact pressure and POLPD, while identifying bedside applicable, simplified clinical risk indicators.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>In this prospective observational study, 89 patients undergoing elective surgery (\u2265 2 hours) were enrolled. We adapted a T-scan III occlusal analysis system to measure tracheal tube pressure distribution at four intraoperative timepoints. POLPD was defined as a composite endpoint including severe pharyngalgia (NRS \u2265 4), profound dysphagia (bedside water swallow test \u2265 4), or prominent tongue edema.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>POLPD incidence was 39.1%. Multivariate analysis identified two independent risk profiles: female with narrow pharyngeal cavity (OR 3.26, 95% CI: 2.1\u20134.87, P &lt; 0.001) and prone position with non-neutral O\u2013C2 angle (OR 1.94, 95% CI: 1.34\u20132.81, P &lt; 0.001). The POLPD group had significantly higher tracheal tube pressures. A pressure-overload index independently predicted POLPD (OR 1.17, 95% CI: 1.01\u20131.37, P = 0.041), demonstrating a dose-response relationship.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>This study provides quantitative evidence linking tracheal tube contact pressure to POLPD.
