This study aims to develop and validate a quantitative prediction model using three-dimensional computed tomography (3D-CT) imaging for identifying infants with Pierre Robin sequence (PRS) at risk of difficult laryngoscopy. A dual-parameter model incorporating the oropharyngeal sagittal area (S2) and the distance between the tongue base and the posterior pharyngeal wall (D4) will be established. Internal validation will be performed using data from PRS infants treated between 2023 and 2024, and temporal external validation will be conducted using an independent cohort from 2025. This study seeks to provide an accurate, non-invasive tool for preoperative airway risk assessment in PRS infants, thereby improving anesthetic safety and clinical decision-making.
