Artificial Intelligence and Facial Analysis/Facial Nerve/Facial Palsy.

Artificial intelligence (AI)-based facial analysis enables objective and quantitative evaluation of facial morphology. Recent advances in computer vision allow automated detection of facial landmarks and reproducible measurement of facial symmetry, movement, and emotional expression. Several AI systems, including Emotrics, MediaPipe Face Mesh, Real-Time Facial Asymmetry Analysis, FaceReader, and Affdex, have been applied to outcome assessment after facial reanimation procedures and facial nerve reconstruction. Similar computational approaches can also be applied to evaluate structural facial deformities, such as those observed after mandibular reconstruction. By reducing subjective bias and improving reproducibility, AI-based facial analysis may support more evidence-based evaluation of reconstructive surgical outcomes.
