AI-Based Angle Map Analysis of Facial Asymmetry in Peripheral Facial Palsy
Peripheral facial palsy (PFP) causes significant facial asymmetry and functional impairment, demanding reliable, objective assessment. This study introduces a novel, fully automated, reference-free method for quantifying facial symmetry using AI-driven landmark detection. Analyzing 405 datasets from 198 PFP patients, the method detects 478 landmarks per image to compute local asymmetry angles. A systematic evaluation identified 91 highly informative landmark pairs, primarily around the eyes, nose, and mouth, enhancing discriminatory power and enabling region-specific asymmetry assessment. Statistical analysis showed moderate to strong associations (0.32-0.73, p < 0.001) with clinical scores. This AI-driven approach offers a robust, objective, and visually interpretable framework for clinical monitoring, severity classification, and treatment evaluation in PFP, combining quantitative precision with practical applicability.
