Plastic surgery is the specialized surgical division that manages the structural deformity, congenital anomaly, and functional deficit. As it were, plastic surgery is the surgical department correcting congenital and acquired deformity to restore them close to the normal status in its function and appearance.
In this concept, plastic surgery is also called 'Plastic and Reconstructive Surgery'. The term 'Plastic' is often replaced with 'Aesthetic'. Aesthetic surgery implies that it tries to make things superior to the average, while reconstructive surgery means that it tries to make things normalized.
In general, plastic surgery includes these two categories. However, it is hard to clarify and divide these areas. It is classified according to what is more emphasized on each procedure.
