He introduced that the incidence of microtia is increasing year by year. According to the statistics of 92 birth testing centers in China, the incidence of microtia is 1/4000, which is the second most common facial contour deformity after cleft lip and palate. And there are more boys than girls, especially right deformity. "There are 650,000 patients with microtia in China and 40,000 in Guangdong. Every year in China, 10000 newborns are born with microtia. In addition to different degrees of external ear malformation, children will also have moderate to severe hearing impairment due to atresia or stenosis of the ear canal. " Professor Amber said.
It is best to operate when the child is about 6 years old.
Because the ear is in the head and face, the deformity is obvious, and parents hope to correct the child as soon as possible. Sisi's mother told reporters, "Sisi is only five and a half years old. Now he is in kindergarten. He has no concept of ear deformity and is carefree. On the contrary, our parents care most about other people's eyes. I am waiting to operate on my child now. "
Surgical correction mainly solves two problems: one is auricle reconstruction to solve external ear defect; Second, the ear canal and hearing reconstruction, so that children can hear. The treatment of patients with unilateral microtia and bilateral microtia is slightly different. According to statistics, there are about110 in children with bilateral microtia. Hearing reconstruction and vibration bridge implantation must be carried out as soon as possible to ensure the normal development of children's speech function. Therefore, children with bilateral deformities should have hearing reconstruction at the age of 3-4, and auricle plastic reconstruction before 10.
