They are also known as the ear, parotoid, or seed ear, and are superfluous tissues located in front of the ear screen, often on the line from the ear screen to the corner of the mouth, and are caused by abnormal development of the first gill arch. The shape and size of these ears vary, and most of them contain cartilage, some of which are connected to the ear cartilage, while others reach into the subcutaneous tissue of the cheek, or are deeper than the parotid fascia, and some may be accompanied by facial fissures. The principle of treatment is surgical excision, and care should be taken to remove the embedded cartilage as deeply as possible. There is no clear optimal age for this procedure. In recent years, because the family pays more attention to the child’s aesthetics, they hope to eliminate the psychological impact on the family and the child by early surgery, which is a minor outpatient surgery, simple and less time consuming, and the younger the child, the less psychological impact on the child, but the younger child is not cooperative in surgery and needs anesthesia assistance, so a hospital with pediatric anesthesia is needed; another condition is that because the child is small (we usually operate when the child is 3-6 months old) The smaller the scope of surgery, the more delicate the child’s skin is, the more experienced the plastic surgeon needs to be for fine and surgical manipulation and suturing, so that better post-operative results can be obtained.
