Abstract: Improvement of the jawline contour is a critical focus in lower face and neck rejuvenation treatments. Achieving a well-defined, smooth jawline is a shared goal between patients and plastic surgeons. This article reviewed recent research on age-related changes of the jawline and evaluation method, offering valuable references for jawline rejuvenation treatments.The jawline’s unique anatomical position, coupled with age-related changes, involves dynamic alterations in bone, soft tissue, and skin across multiple layers, making rejuvenation of this area a complex and challenging task. In recent years, advances in imaging technologies such as two-dimensional photography, three-dimensional stereophotogrammetry, computed tomography, magnetic resonance imaging, ultrasound, and micro-CT have expanded the understanding of jawline anatomy and provided precise tools for analysis and evaluation.
