Why is there a secondary ear?

  The epiglottis, commonly known as the small ear, is a redundant tissue located in front of the ear screen, often on the line from the ear screen to the corner of the mouth, and is caused by abnormal development of the first gill arch. They come in a variety of shapes and sizes, and most contain cartilage, either attached to the ear cartilage or extending into the subcutaneous tissue of the cheek or deeper than the parotid fascia.  The probability of having an ear attachment is not low, usually around 15%, and it is genetically related, so it is normal for your family to have an ear attachment if your grandparents had one, so there is no need to panic. The treatment for an ear attachment is to remove the ear, remove the cartilage contained in it, and close the wound with appropriate adjustments. Patients with an attached ear often have facial dysplasia on the same side, so the cartilage can be removed with only the elevated portion removed, leaving the subcutaneous portion of the face intact to avoid aggravating the facial deformity.  The treatment involves excision of the appendage and removal of the cartilage contained therein, with appropriate adjustment of the incision sutures. Patients with an adnexal ear are often associated with ipsilateral facial dysplasia, so only the elevated portion of the cartilage can be removed while the subcutaneous portion of the face is preserved to avoid aggravating the facial deformity. In the case of an appendage that is fused to the ear screen in front of the ear screen, it can be used to reconstruct the ear screen during excision. This is usually not a problem and should not require surgery. It is a natural flaw to have such a piece growing in front of the ear, and although it is not painful, most people request surgery because it affects their facial appearance. The surgery only requires the removal of this piece of redundancy protruding from the skin. If there is also a preauricular fistula, it is usually not necessary to dig deep into the cartilage root, the surgery is relatively simple and short, and the scar will gradually disappear a few days after the surgery.
