Facial asymmetry, being a common phenomenon, was probably first observed by the artists of early Greek statuary who recorded what they found in nature – normal facial asymmetry. This may be the result of discrepancies either in the form of malposition of one or more bones in the craniofacial complex or in individual bones. The symmetry may also be limited to the overlying soft tissues. Macgregor defined disability as any condition which prevents one from performing the normal activities of daily living. Yet the inability of the facially disfigured to lead normal lives tends to be overlooked because they are ostensibly able-bodied, can work, and can physically accomplish the basic routines of daily living. Peck and Peck estimated that the bilateral facial symmetry at 52 is “exceptionally well-balanced” in white adults and also noticed the lesser asymmetry and more dimensional stability as the cranium is approached. Significant facial asymmetry causes both functional as well as aesthetic problems. When patient complains of facial asymmetry, the underlying cause should be investigated.
