Quantification de la dissymétrie faciale : méthodes et applications

Facial asymmetry, present in all human faces at varying degrees, plays a critical role in clinical fields such as orthodontics, orthognathic and plastic surgeries, and craniofacial reconstruction. Accurate quantification of facial asymmetry is essential for diagnosis, treatment planning, and post-surgical evaluation. This article examines contemporary methods for quantifying facial asymmetry, including two-dimensional (2D) and three-dimensional (3D) landmark-based approaches, surface curvature analysis, and advanced image-based techniques. Emphasis is placed on the advantages, limitations, and applications of each method, to meet clinical or research needs. By integrating technological advancements, future developments are expected to enhance precision and applicability in clinical practice.
