One of the most common questions asked by parents of children with microtia is whether this condition is genetic or hereditary. In other words, families often wonder whether microtia can be passed from one generation to the next.
Clinical studies show that there may be a familial predisposition in cases known as syndromic microtia, where microtia occurs together with other congenital anomalies. However, in sporadic microtia cases — where the condition appears alone without other anomalies — no specific genetic transmission has been identified.
Another frequently asked question is whether microtia is hereditary. According to current scientific publications, the probability that a person born with microtia will pass the condition on to their child is quite low — approximately 5%.
Nevertheless, some individuals may have a genetic predisposition. In rare cases, familial patterns of microtia have been observed both in scientific literature and among patients in clinical practice.
Although children born with microtia often undergo many medical tests, genetic testing is usually unnecessary when microtia occurs alone. In fact, more than 90% of microtia cases are isolated cases without any additional anomalies.
However, if microtia occurs together with other congenital anomalies — such as Goldenhar Syndrome or Treacher Collins Syndrome — genetic testing may be recommended to determine the underlying cause and assess the possibility of recurrence in future generations.
In addition, several medical examinations may be required to detect accompanying anomalies:
Performing these examinations early in the postnatal period is important in order to plan appropriate treatments without delay.
