Surgery has always been a blend of art and science, and, plastic surgery is a further extension of it, where, one is involved in the restoration, reconstruction and or alteration of human body or its part.
2. Aesthetic/ cosmetic
In the reconstructive part we deal with restoration of lost or deformed part of the body be it either from birth or resulting from some unfortunate event ( trauma / burn) such as soft tissue, limb or part of it, nose, ear etc.
Aesthetic surgery may be considered as an extension of reconstructive surgery in a sense where, you try to reconstruct or restore the deviation or loss from perceived normal ( beautiful ). By aesthetic or cosmetic surgery we try to restore the perceived normal at the same time taking into consideration that the change remains in harmony with the rest of the body.
