Patient: Patient female, 4 months old, congenital atresia of the right ear, normal appearance of the left ear, limited to local medical conditions, no hearing screening of the left ear was done. Not examined locally 1. Can I ask you to see the doctor? 2.What is your initial diagnosis of my child’s disease? 3.Can I fly? 4. Please give me some advice on treatment. Chen Yang, Department of Otolaryngology, Xijing Hospital: The birth rate of congenital microtia is about 1 in 7,000. If it is unilateral and the hearing on the opposite side is normal, otoplasty can be performed after the age of 7, mostly by plastic surgery; hearing reconstruction can be done after puberty by consulting an experienced otologist. In the case of bilateral atresia, bone conduction hearing aids should be started before the age of 1 year to avoid interfering with hearing and speech development. A high-resolution CT (preferably a 3D reconstructive spiral CT of the auditory chain) is required before performing hearing reconstruction surgery, so it is not recommended that children with monaural lesions go for a cranial CT right after birth. because of the increased radiation exposure and the need to re-take the films again most of the time by the time of surgery. Then, there is only one condition that requires early intervention, and that is the presence of ear discharge, the cause of which may be secondary to cholesteatoma infection and requires immediate surgery. Hearing reconstruction is done with an ear canal tympanoplasty, which needs to be done by an experienced ear surgeon. The main risk of the surgery is that hearing may not always improve, for reasons such as re-stenosis of the ear canal, outward displacement of the eardrum, etc. The success rate is about two-thirds. Those who cannot improve their hearing with canal tympanoplasty can undergo bone anchored hearing aid implantation or vibrating sound bridge implantation.
