The optimal age for surgery for congenital microtia is usually between 6 and 8 years of age.
Congenital microtia and middle ear malformation often occur together, the former is caused by the dysplasia of the 1st and 2nd gill arches and the developmental disorder of the 1st gill groove. The latter is associated with hypoplasia of the 1st pharyngeal bursa, which can lead to malformations of the structures within the tympanic cavity, the Eustachian tube and even the mastoid process. In the case of monaural malformations with normal hearing in the opposite ear, surgery is usually performed between the ages of 6 and 8 years.
The physiological functions of the child tend to be more robust during this period, and the risk of anesthesia is relatively reduced compared with that at a younger age, so there is a certain advantage in choosing the timing of the surgery. Children’s sense of autonomy is gradually formed at this stage, and surgery at this time can reduce the negative impact of the disease on children’s mental health. Children’s ear development is not very different from that of adults at this age, so surgery at this time can minimize the possibility of later changes.
When suffering from congenital malformations, it is important to consult a doctor for a systematic examination to clarify the diagnosis and condition, and to follow the doctor’s instructions for standardized treatment.
