Facial asymmetry refers to noticeable differences between the left and right sides of the face in terms of shape, volume, muscle activity, or skeletal structure. Mild asymmetry is normal and present in nearly all individuals; however, pronounced asymmetry can affect facial harmony, self-perception, and confidence. In selected cases, facial asymmetry may also have functional implications.

Facial asymmetry may be congenital, developmental, post-traumatic, or acquired due to aging, nerve injury, muscle imbalance, or previous surgery. Conditions such as facial nerve palsy, skeletal discrepancies, uneven fat distribution, or asymmetrical aging contribute to visible imbalance. In some individuals, asymmetry becomes more noticeable over time due to differential tissue laxity or muscle activity.

Patients with facial asymmetry often report dissatisfaction with photographs, facial expressions, or profile appearance. Some experience difficulty with facial movements, speech, or eye closure depending on the underlying cause. Psychological impact can be significant, especially when asymmetry affects key facial features.

Evaluation involves detailed facial analysis, including skeletal structure, soft-tissue volume, muscle function, and symmetry during rest and expression. Understanding the cause of asymmetry is essential to determining appropriate management.

Management aims to restore balance rather than absolute symmetry. Treatment strategies are individualized and may involve non-surgical or surgical correction depending on severity and etiology. In selected cases, staged correction may be recommended to achieve natural results.

Addressing facial asymmetry improves facial balance, confidence, and overall aesthetic harmony. When approached conservatively and ethically, plastic surgery can achieve subtle yet meaningful enhancement while preserving individuality.
