Double auricle defect
Introduction
Introduction Auricle defects are caused by trauma or infection, and have characteristics compared with tissue defects of congenital micro-ears. For example, local skin often has scars, blood supply, elasticity, and slack. It is not possible to make a thin subcutaneous peeling, and it is not easy to form a wide and loose cavity that can accommodate the implanted tissue. Therefore, it is often difficult to clearly display the contour shape carved on the stent.
Cause
Cause
Auricular defects can be caused by trauma, burns, tumor resection, and the like. The auricle is deficient, and the surrounding skin often has more scars, elasticity, blood supply, and looseness. Most of the ear and outer ear canal are often left, but even if the defect is serious, some ear and outer ear canal remain, so that the ear can be recreated. The profile is easy to obtain a better shape. The repair of auricle defects can be based on the basic principles of total auricular reconstruction, combined with the location, size and local tissue of the defect, and appropriate surgical methods and tissue transplantation for repair.

1. Have a history of trauma or infection or surgical removal of the tumor; recreate the skin of the auricle, first use the skin of the posterior mastoid area, when it is not enough, it is possible to expand the skin or other methods.
2. The auricle defect, the surrounding skin often has more scars, elasticity, blood supply, and looseness; the auricle stent can be made of autologous cartilage or other materials. It is extremely important that the bracket is engraved into the shape of the auricle.
3. Frequent residual ear and external auditory canal; suspected of other facial features or complications after surgery, the inspection project may include the check box "A", "B".
4. Can be combined with other malformations. Under normal circumstances, check the project to check the frame limit "A";
Diagnosis
Differential diagnosis
Need to be identified with the following symptoms:
Auricle dysplasia: auricle dysplasia generally refers to congenital microtia, which is the first in the process of embryonic development, the second zygomatic arch or the first sulcus dysplasia, may be associated with the first pharyngeal stenosis Caused by eustachian tube, tympanic cavity or mastoid deformity.
Auricular ear canal laceration: Auricular ear canal laceration is a clinical manifestation of ear trauma. Auricular trauma can occur alone or with trauma to adjacent tissues, with contusions and lacerations more common.
The auricle becomes larger: the cyst of the abdomen of the ear is unexplained. Because of its absence of epithelial layer, it is called a pseudocyst. The majority of patients are male, and the age of onset is generally 30 to 40 years old, mostly occurring in one side of the auricle.
1. A history of trauma or infection or surgical removal of a tumor;
2. The auricle defect, the surrounding skin often has more scars, elasticity, blood supply, and slackness;
3. Frequent residual ear and external auditory canal;
4. Can be combined with other malformations.
