The ears, another important feature in the beauty of a face, could present some issues that in plastic surgery is known as prominent ears or cup ear, those that protrude too far from the head.
The reason why prominent ears stand far apart from the skull is that the cartilage did not bend appropriately, so the ear is open and not bent, which is the normal form for the human being.
The purpose of the procedure is to give the ear the bend on that cartilage, and achieve a natural and harmonious ear appearance with the face.
The ear development in humans begins with the embryo and by 6 months they are practically fully formed. These stop growing at age 7 and that is why they can be operated on that early.
