Children have congenital microtia, what are the consequences?

Congenital microtia, or congenital external middle ear malformation, manifests as severe auricle dysplasia, external auditory canal atresia or stenosis, middle ear malformation, and inner ear development is mostly normal, with certain hearing through bone conduction. It needs to be treated by reconstruction of the whole ear and reconstruction of the hearing function.


Congenital microtia

Congenital microtia can occur either alone or in part of the syndrome. Common combinations include: Treacher Collins syndrome, Goldenhar syndrome, Nagar syndrome, and Miller syndrome.

The cause of congenital microtia

The exact pathogenesis of congenital microtia is not very clear and may involve various factors such as heredity and pregnancy. But it can’t be said that it is the problem of the father or the mother. There is no evidence to prove that this is caused by diet, work and illness during pregnancy. Therefore, parents should not guess each other and complain.

Clinical manifestations of congenital microtia

The clinical features of patients with congenital microtia are mainly in the auricle, external auditory canal and middle ear, and the inner ear is often not affected. According to the degree of deformity, the most commonly used type in clinical is type III:


Congenital microtia

I degree: the size and shape of the auricle change, but the important surface marker structure of the auricle exists, the external auditory canal is narrow, and the external auditory canal is blocked when severe;

II degree: the most typical, only the vertical direction of the ear wheel, the shape of the sausage, the external auditory canal;

III degree: only the agglomerates of skin and cartilage remain, and there are no ears in severe cases.


Congenital pediatric malformation

There are more than ten types of middle ear developmental disorders in patients with congenital microtia, mainly for the developmental malformations of the small bone, tympanic muscle and facial nerve, and are closely related to the severity of external ear malformation. Congenital external ear malformations can be manifested as one of the clinical signs of serial signs in severe cases, such as the Oculo–auriculo–vertebral spectrum (OAVS). In addition to the presence of small ear malformations, the patient also suffers from a short half-face (sacral, maxillary or mandibular dysplasia), soft tissue malformation (anterior or anterior auricular deformity), orbital defect (orbital defect, conjunctival epithelial cyst), spine Malformations, as well as congenital kidney and heart defects.

Does congenital microtia deformity affect hearing?

Most of the congenital microtia deformities are accompanied by abnormalities in the ear canal and middle ear, but most of the inner ear is normal. In other words, the child has hearing, but it is worse than the opposite side. Regarding whether it is necessary to open the ear canal through surgery, this varies from person to person. Getting through the ear canal will improve your hearing to some extent, but it will not be the same as normal. Therefore, if the unilateral small ear deformity, the meaning of opening the ear canal is not significant, if both sides, you can consider opening the ear canal to improve hearing.
