Patient: Congenital Never been examined My daughter is 5 months old and has a malformed right ear with atresia and a normal left ear. Is it appropriate to do CT examination at such a young age? Or should I wait until the child is 3 or 4 years old? Can we wait until she is about 6 years old to open the ear canal atresia when she has an external auricular reconstruction or should we open it first? Zhang Ruhong, Department of Plastic Surgery, Shanghai Ninth People’s Hospital: We have a general understanding of the patient’s situation and the answer is as follows. 1. Patients with unilateral microtia and atresia generally do not have a great impact on their hearing, so it is not recommended to open the ear canal. 2. Ear reconstruction surgery requires the skin in the reconstructed ear area to remain intact, so if the ear canal is opened, it will greatly affect the effect of ear reconstruction and even prevent ear reconstruction surgery. 3. The best age for ear reconstruction surgery is 6-12 years old, and surgery is not recommended below 6 years old.
