facial asymmetry
Deviation from normal bilateral symmetry of facial structures, often requiring surgical correction in severe cases.
Full Definition
Facial asymmetry refers to the lack of symmetry between the left and right sides of the face, which can affect both hard and soft tissues. It may be congenital, developmental, or acquired through trauma, infection, or pathological processes. Asymmetry can involve the mandible, maxilla, orbital region, or soft tissues, and may impact both function and aesthetics. Assessment typically involves clinical examination, photography, and cephalometric analysis. Treatment approaches range from orthodontic therapy to complex orthognathic surgery depending on the severity and underlying cause. Mild asymmetries are normal, but significant deviations often warrant intervention.
Usage
Usage note: Distinguish from normal minor asymmetries that do not require treatment.
