The auricle is cut and torn, ranging from a crack to a tissue defect, and the auricle is torn or completely torn. After strict disinfection, the wound should be debrided and sutured to preserve cartilage tissue as much as possible. If the skin defect is large and the cartilage is still intact, pedicle flap or free flap can be taken from behind the ear for transplantation. For example, some cartilage and skin are completely broken, so you can do wedge-shaped resection of the edge, and you can use fine needles and thin lines to suture, and you can't penetrate the cartilage when sewing.
When the ear is cut off from the injured person, it is washed with hydrogen peroxide and physiological saline and soaked in antibiotic solution for a quarter of an hour. If the auricular artery can be found, rinse it with heparin, then anastomose the blood vessels and suture the broken ear skin with subcutaneous tissue. Or cut off the broken ear skin and implant auricle cartilage under the skin behind the ear. After survival, the implanted auricle cartilage and skin were lifted and transplanted to the original auricle wound to form a new auricle. If the interval is too long, or the wound is infected, it is not suitable for suture. Skin around the external auditory canal and mastoid skin should be sutured in place to avoid external auditory canal stenosis.
