Conditions

Facial Asymmetry

Brief summary

Facial asymmetry, the degree to which the two sides of the face differ in size, shape, or the arrangement of features, is a near-universal human characteristic. The intricate network of facial muscles plays a crucial role in both the static structure and the dynamic expressions of the face. The continuous pull and action of facial muscles can influence the development and positioning of underlying soft tissues and even, over extended periods, potentially impact skeletal structures.
