While both procedures aim to improve the appearance of the chin, they differ in their approach and outcomes. Chin augmentation specifically involves increasing the chin’s projection, volume, and definition, typically through the use of an implant when done surgically. On the other hand, mandible contouring surgery reshapes and reduces the size of the entire jawbone to create a slimmer, softer jawline. Mandible contouring involves more extensive bone work, such as bone shaving, cutting, or repositioning, and focuses on the entire jawline. While both procedures aim to enhance facial aesthetics, chin augmentation is less invasive and has a quicker recovery compared to extensive jawline procedures such as mandible contouring surgery.
