Since microtia is a condition that involves both otoplasty and hearing reconstruction (and, in the future, psychological interventions for children), the treatment of microtia is, from a medical point of view, a cross-disciplinary one: it requires that the surgeon has experience in middle ear surgery (for hearing reconstruction) as well as skills in auricular surgery (for otoplasty). Many parents prefer to have the same surgeon perform both parts of the surgery, and this is the right concept. Because of this, the surgeon is able to make an overall surgical plan for the child (e.g., hearing reconstruction or auricular first? How many times will the surgery be divided?) ), and will be able to anticipate and adjust the next surgery based on how the last surgery went and how difficult it was. If you take over a child who has had surgery at another hospital, the surgeon will often lack sufficient information from the last surgery when performing the new surgery, objectively making it more difficult and risky. Both otoplasty and hearing reconstruction surgery for ear malformations are challenging techniques within the discipline and require a high level of training background and clinical experience. Although there is no access system for this type of surgery in the world, most experts agree that a surgical center that performs a small number of similar surgeries, such as a dozen or so per year, is not equipped to perform this work. Therefore, when choosing a center to receive treatment, parents should pay attention to the center’s past performance, and try to choose an operator and unit with a longer period of time, a larger number of cases, and a wealth of experience.
