Which bony structure determines the width of the face?

The peak of the zygomatic arch plays a crucial role in determining the width of the face due to its position and structure. The zygomatic arch, often referred to as the cheekbone, is formed by the zygomatic bone and contributes significantly to the lateral aspect of the face. The peak, or highest point, of this arch is a key area that gives the face its characteristic width, especially when viewed from the front. It acts as a measuring point for facial measurements and is used in various assessments, including aesthetic evaluations and anthropometry.

The maxilla and mandible contribute to the overall structure of the face, but they do not specifically define its width in the way that the zygomatic arch does. The maxilla is the upper jawbone that houses the upper teeth and forms the palate, while the mandible is the lower jawbone. Although both are essential for facial structure and function, they are more involved in the vertical dimensions and the shape of the oral cavity.

The biparietal structure refers to the distance between the parietal bones of the skull and relates more to the width of the cranium rather than the face itself. This means that while it has its importance in overall head dimensions, it is not
