Goldenhar syndrome is an uncommon congenital condition characterized by underdeveloped bones and muscles in one or both facial regions, often accompanied by malformations of the ears and eyes, as well as abnormalities in the vertebrae. The syndrome is named after the researcher who initially identified it in 1952.
Goldenhar syndrome is also known as oculo-auricular-vertebral dysplasia or hemifacial microsomia. There are 3 main symptoms and they can affect only one side of the face or body:
For experts, the cause of Goldenhar syndrome is still unclear. It is a rare disease, affecting between 1 in 3,500 and 1 in 25,000 newborns, with a slightly higher percentage in males.
The underlying causes are believed to be multifactorial, involving a complex interplay of genetic and environmental factors. While most cases are sporadic, approximately 2% of instances are familial in origin, potentially stemming from one or both parents. Research suggests that certain medical conditions or factors may heighten the risk of developing Goldenhar syndrome. These include conditions like gestational diabetes and the use of retinoic acid, a common acne treatment drug.
Currently, there is no definitive cure for Goldenhar syndrome, and treatment strategies are tailored to the specific conditions, the severity of malformations, and their nature. In cases where Goldenhar syndrome is mild, especially in children, treatment may not be necessary.
However, if the situation is more complex, the approach may vary according to the patient's needs. Skull malformations, eye irregularities and vertebral abnormalities may require various types of intervention, including surgical procedures. Hearing impairments can be addressed with the assistance of hearing aids or specialised devices. Feeding difficulties might require the use of special feeding bottles or even direct nutrient intake into the stomach. Speech disorders can benefit from speech therapy sessions.
The diagnosis of Goldenhar syndrome in children is based on the presence of the physical symptoms that characterise it. Amongst others, ear abnormalities are essential to consolidate the diagnosis, but there are no actual tests to confirm it. However, genetic tests can be performed to rule out certain diseases that have common features with this disorder, and additional tests can be used to corroborate the diagnosis, such as CT, echocardiogram or electrocardiogram, eye examinations, ultrasounds, X-rays and sleep studies.
Goldenhar syndrome is rarely diagnosed prenatally, but changes in the jaw, ear or mouth may possibly be noted during ultrasound imaging of the foetus.
At present, it is not possible to prevent Goldenhar syndrome, partly because the causes of the disorder are not fully known. However, it is important to follow good general practices and your doctor's instructions during pregnancy.
If there is a family history of Goldenhar syndrome, genetic testing and counselling can help to understand the likelihood of the disorder occurring.
Many disorders may have symptoms similar to those of Goldenhar syndrome, such as:
