What is microtia? Microtia is a form of atrasia. Atrasia is the condition of an abnormal windup or absence of a physical orifice. So, microtia is an ear deformity where the outer ear is underdeveloped from birth. The ratio of children born with microtia is 1/9,000. Microtia is not among the common birth defects, although, microtia is a known complication of children born if the mother took the drug Accutane while pregnant. This atrasia of the ear may sway both (bilateral) ears or only one (unilateral) ear. There are varying degrees grading 1-5 of microtia. 1 being a gift and formed, but slightly deformed and small external ear and ear canal, to 5 being the complete absence of an external ear and ear canal. Microtia may be an unfortunate birth defect, but thankfully with modern rehabilitation today, it is treatable.
The level of hearing loss of children born with microtia may vary depending on the conditions' severity. A special hearing test can resolve how much the child can hear and which is the best advent to treat it with. Usually the inner is intact and healthy, so some children are candidates of surgery to generate an ear canal to improve conductive hearing. Other children born with more severe grades (those including aural atrasia) of microtia may be best off receiving a cochlear implant to amplify sounds to the inner ear. Speech therapy is also encouraged for children born with microtia. Because of hearing loss, most sound are muffled, so precise enunciation is often taught by a speech therapist. Unilateral microtia was not carefully a serious disability until the 90's, because it was idea that the child could adjust to it from birth.
