This disease is caused by the hypoplasia of the first and second branchial arches or the first branchial groove during embryonic development. The operation should be completed as early as possible before school age. Generally, the best operative age is from 6 years old to before puberty (about 14 years old). Guidance: Don't go to see a doctor if you are sick. The right medicine is the key. Please take symptomatic treatment under the guidance of a doctor to achieve a quick cure and relieve your pain as soon as possible. Please press the word (consult an expert), which means hello. The so-called ear points forward, and the distance from the auricle to the posterior bone of the ear is more than two centimeters. Children's ears have developed close to adults at the age of four, so most operations are carried out between the ages of 4- 14. The earlier the operation, the less ridicule and psychological harm the child will suffer. But unless the child asks to change the shape of the ear, there is no need to force the child to have an operation. Adult ears can also be surgically corrected.
