Microtia is a congenital disorder that results in the malformation or absence of the outer ear. This condition, which strikes one in every 6,000 to 12,000 births globally, does not discriminate across genders or ethnicities. Microtia can be unilateral, affecting one ear, or bilateral, affecting both. However, in 90 percent of the cases, it is the right ear that is affected.

The degree of ear malformation varies across four grades of microtia, ranging from Grade I, where the ear is slightly smaller but has recognisable features, to Grade IV, referred to as anotia, where the external ear is entirely absent. The condition can present itself as a part of a syndrome or in isolation.

Interestingly, microtia is often associated with a condition known as aural atresia. Aural atresia is a hearing disorder that arises due to the malformation or closure of the ear canal, hindering the transmission of sound waves to the middle ear. Consequently, individuals suffering from microtia may face challenges with their hearing capabilities, depending on the severity of the associated aural atresia. It is noteworthy that the inner ear, responsible for balance, usually remains unaffected in these cases, thus maintaining the neural pathway for suitably designed hearing aids functionality.

When it comes to the potential causes of this condition, the exact factors are yet to be confirmed. Nevertheless, various theories suggest it may be due to genetics, environmental aspects, or a combination of both. For instance, exposures to certain prescription drugs, high levels of alcohol or tobacco consumption during pregnancy have been associated with a higher risk of developing microtia.

Turning our focus towards severe facial conditions that may present with microtia, Treacher Collins Syndrome (TCS) is an example. TCS is a condition that affects the development of bones and facial tissues. It is characterized by downward-slanting eyes, abnormalities of the external ears, underdeveloped jaws, and often the presence of cleft palate. While TCS is rare with an estimated incidence rate of 1 in 50,000, about half the individuals with TCS have the condition due to a new genetic mutation, and the other half inherit it from a parent.

Is there a treatment for Treacher Collins Syndrome? The treatment strategies aim to address the various physical characteristics and health problems related to the syndrome. Surgical interventions, including craniofacial surgery, may be considered to address facial bone abnormalities. For ear defects, including microtia, reconstructive surgeries or prosthetics may be chosen.

As for microtia itself, it is usually managed through surgery, prosthetic ears or non-surgical options like bone conduction hearing aids, depending on the severity of the condition, associated hearing loss and parental preferences. A multidisciplinary approach where paediatricians, ENT specialists, audiologists, plastic surgeons, psychologists, and speech therapists work together is essential for the effective management of microtia.

Reliable diagnosis and early intervention are crucial in treating microtia and associated conditions. Therefore, neonatal screening for such congenital deformities is highly recommended. Remember, each child is unique, and their treatment plan should be customised to meet their individual needs and improve their quality of life.
