beckoning ears
Introduction
Introduction The ear is a common congenital auricular deformity, which is generally thought to be due to the formation of incomplete follicles or the formation of ear cartilage in the embryonic stage. These two parts of the deformity may exist alone or simultaneously. The bilateral characteristics of the ear are more common, but the degree of deformity on both sides is different. The same deformity can usually be found in both parents and siblings.
Cause
Cause
Due to the embryonic stage, the formation of incomplete ear or ear cartilage is formed. The composition of the deformity is mainly due to the excessive angle of the stern angle. It is characterized by a flat auricle, a right angle to the skull, and a large auricle, which is not completely opposite. The ear wheel is underdeveloped, the ear nails are deep, the normal anatomy of the ear canal and the ear wheel disappears, the upper part of the auricle is flat, the angle of the scapula is greater than 150° or completely disappears. The distance between the upper end of the normal adult auricle and the cranial side wall is less than 2 cm, and the angle between the whole auricle and the cranial side is 30°. The wind is expressed as the overrun of this distance, and the expansion of the angle is about 90°. Most of the deformities are on both sides, the degree of lightness and weight may be different, or only on one side. At the time of treatment, men are often more, and women are covered by hair and have some concealment.

Clinical manifestations:
1. The auricles of both ears stand prominently to the outside, or they can only be seen on one side.
2. The distance between the upper end of the auricle and the cranial wall is greater than 2cm, and the angle is about 90°.
3. The upper part of the auricle is flat, the angle of the scapula is greater than 150° or completely disappears.
Diagnose based on:
1. Congenital auricular deformity.
2. The malformation is mainly caused by the angle of the stern angle.
3. The performance of the auricle is flat, approximately perpendicular to the skull, the auricle is large, mostly bilateral, not completely symmetrical. The ear wheel is underdeveloped and the ear is deep. The normal anatomy of the ear canal and the ear wheel disappeared, the upper part of the auricle was flat, and the angle of the scapula was greater than 150° or completely disappeared.
Diagnosis
Differential diagnosis
Cup-shaped ear: is a congenital malformation between the ear and the ear, accounting for about 10% of various congenital ear malformations. Bilateral is more common, but the left and right are not necessarily symmetrical, and there is a certain heritability. The cup ear has four main features: the auricle is curled, the light one is only the self-folding of the ear wheel, and the heavy one is the upper part of the auricle, covering the ear canal.
The auricle is tilted forward, that is, the ear is ear-splitting, but it is different from the simple ear-ear deformity. The auricle becomes smaller, mainly because the length of the auricle becomes shorter. The position of the auricle is low, the severity is more obvious, and often accompanied by maxillofacial deformities. The cup ear is also often referred to as a curled ear, a lop ear, etc., because its shape seems to wear a rope early on the flange and tighten it. Therefore, some people call it a ring ear.
Cauliflower ear: After the auricle is squeezed or collapsed, the hemorrhage is formed by oozing blood under the ear cartilage, which leads to avascular necrosis of the ear cartilage. The necrotic tissue gradually becomes a connective tissue, and the fibrous connective tissue is prone to contraction. As a result, the auricle gradually thickens and collapses, and many irregular shaped protrusions appear on the surface, and there are shrunken gaps between the protrusions, which are shaped like cauliflower, and thus are called cauliflower ear malformations.
The accessory ear: also known as deafness, commonly known as the small ear, is caused by abnormal development of the first zygomatic arch. Usually, there are twins with different shapes and sizes on the line connecting the front of the tragus and the mouth. There are often some cartilage in the tissue. Tissue, the surface of the skin is sometimes colored, and the accessory ear is completely redundant. It has nothing to do with the function of hearing, although sometimes the accessory ear cartilage can be connected to the ear cartilage and sometimes into the tissue of the cheek, but Are waste organizations that have no effect.
