Microtia is a deformity that affects the development of the auricular pavilion, which is the outer part of the ear. This condition can manifest itself in different ways: from a small and deformed ear, to the total absence of structure.
This anomaly not only shows aesthetic problems, but also affects the hearing of the person who suffers it, making it an important issue within the field of otorhinolaryngology and pediatric audiology.
Types of microtia
There are different types of microtia, which are classified according to the severity of the malformation.
Grade 1
Generally related to size and shape. In this case, the ear may be slightly smaller than usual or have an irregular shape, but internal structures such as the ear canal are usually relatively well developed.
Grade 2
Grade II is characterized by a more pronounced deformity of the ear. In this degree, in addition to the visible abnormalities, there may be a lack of development in some of the internal structures, such as the ear canal or cartilage that forms part of the auricle.
Grade 3
Grade III represents a more severe form of the condition. In this degree, the atrial hall is either very underdeveloped or practically non-existent. This lack of development can affect not only the aesthetic appearance, but also hearing function, as the inner structures of the ear may also be compromised.
In addition, patients with microtia will face the risk of preventing hearing problems if the condition affects the internal structures of the ear.
Causes of microtia
The exact causes of this condition are not yet fully confirmed, although it may be suspected to be the result of a combination of genetic and environmental factors. Also, it may be generated by taking certain medications during pregnancy as well as exposure to infections that can increase the risk of developing this abnormality within the fetus.
This condition may also appear as part of more complex syndromes, which requires a more severe approach to diagnosis and treatment.
Treatment of the abnormality
The diagnosis of microtia is usually made at birth, but it can also be confirmed by imaging studies such as ultrasound, which help to assess the anatomy of the inner ear and its functionality. As regards treatment, the options depend on the severity of the malformation.
For the mildest cases, wearing hearing aids may be sufficient to improve hearing. In the most severe cases, surgical reconstruction of the atrial hall is a viable option.
This surgery can be performed in several stages and, although it may not always return full hearing functionality, it helps significantly to improve the patient’s aesthetic appearance.
Proper follow-up is crucial to addressing any complications that may arise. This includes monitoring of hearing and overall hearing health, as microtia may be associated with other abnormalities in the middle and inner ear. Therefore, if you suffer from this condition we invite you to visit our hearing center in Malaga to get a comprehensive diagnosis and treatment.
