Ear surgery, or otoplasty, is usually done to set prominent ears back closer to the head or to reduce the size of large ears.
Plastic surgery of the ear is most commonly performed to correct the position of ears that protrude significantly from the sides of the head. Such protrusion makes the ears appear to be larger than normal. Overly large ears are a rare condition called macrotia. Protruding ears may occur on one or both sides in varying degrees and are not associated with hearing loss. Even adult dissatisfaction with previous ear surgery is a basis for plastic surgery of the ear. There are other less common ear deformities that can affect one ear or both, and may or may not affect hearing ability.
The constricted ear, also called a lop or cup ear, has a varying degrees of protrusion, reduced ear circumference, folding or flattening of the upper helical rim, and lowered ear position. The Stahl’s ear is distorted in shape due to an abnormal position of the superior crus, or extra crus to the antihelix. In cryptotia, (or “hidden ear”) the upper rim of the ear is buried beneath a fold of scalp secondary to abnormal folding of the upper ear cartilage toward the head. The folding is the reverse of that commonly seen in the protruding ear.
