facial asymmetry
Deviation from normal bilateral facial symmetry requiring assessment and potential surgical correction.
Full Definition
Facial asymmetry refers to the lack of symmetry between the right and left sides of the face, which may be congenital, developmental, or acquired through trauma, disease, or previous surgery. While minor asymmetry is normal in all individuals, significant asymmetry can affect both function and aesthetics, potentially impacting bite, speech, breathing, and psychological well-being. Assessment involves clinical examination, photography, and often three-dimensional imaging to quantify the asymmetry and plan treatment. Surgical correction may involve orthognathic surgery for skeletal asymmetry, soft tissue augmentation or reduction, or combination approaches. Treatment planning must consider both hard tissue (skeletal) and soft tissue components, as well as the patient's functional needs and aesthetic goals.
Usage
Usage note: Distinguish from specific conditions like hemifacial microsomia; facial asymmetry is a descriptive finding that can have various causes.
