Ear surgery, also known as otoplasty, can improve the shape, position or proportion of the ear by creating an external ear that is of natural proportions, contour and appearance. Any defect in the ear structure that is present at birth or that becomes apparent with development can be corrected by otoplasty. Ear surgery can also treat misshapen ears caused by injury, overly large ears and protruding ears occurring on one or both sides in varying degrees (not associated with hearing loss). The surgeon makes a cut just behind the ear, within the natural crease where the ear meets the head and then removes, reshapes or softens the cartilage and skin to accomplish the desired effect.
