Auricles are vulnerable to various contusions, cuts, lacerations, lacerations and firearm injuries. Improper handling may lead to perichondritis and cartilage.

Necrosis, leaving auricle deformity.

Auricular contusion can rupture blood vessels, and blood will accumulate between cartilage and perichondrium, resulting in hematoma. There are no other symptoms except local swelling and pain. Hematoma mostly occurs in the upper part of auricle, anterolateral, semi-circular purple-red mass, soft. If hematoma is not treated, it will cause auricle thickening and deformation. In the case of infection, suppurative perichondritis may occur. Hematoma can be punctured under strict disinfection, and the fluid can be pumped out and bandaged under pressure. If repeated blood drawing fails, the auricle can be cut under aseptic operation, blood drawn or blood clots removed, and then pressure bandaged. Antibiotics were added to the treatment to prevent infection.

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.

If the ear is broken, wash the broken ear with hydrogen peroxide and normal saline and soak it 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 amputation time is too long, or the wound is infected, which is not suitable for suture, the skin around the external auditory canal should be sutured with the mastoid skin to avoid stenosis of the external auditory canal.
