Protruding ears occur when the ears extend noticeably outward from the sides of the head, often due to an underdeveloped or absent fold in the cartilage that normally brings the ear closer to the skull. This condition is typically present from birth or early childhood and is a structural variation rather than a medical problem. The degree of protrusion varies widely among individuals. While some people are unconcerned about the appearance, others seek treatment for cosmetic or personal reasons.
