Plastic surgery restores and improves function, as well as appearance. It can involve surgery on any portion of the anatomy, except the central nervous system.
Reconstructive surgery is performed on abnormal structures of the body that may be caused by the following:
trauma
infection
developmental abnormalities
congenital (present at birth) anomalies
disease
tumors
Reconstructive surgery is usually performed to improve function, but may also be performed to approximate a normal appearance.
Cosmetic surgery is performed to repair or reshape otherwise normal structures of the body to improve appearance.
