Diagnosing Goldenhar syndrome in children relies on identifying its characteristic physical symptoms. Ear abnormalities play a crucial role in confirming the diagnosis, although there are no specific tests to definitively confirm it. However, genetic tests can help rule out similar conditions, and additional tests, like CT scans, echocardiograms, electrocardiograms, eye exams, ultrasounds, X-rays, and sleep studies, can be used to support the diagnosis. Prenatal diagnosis of Goldenhar syndrome is rare, but certain changes in the jaw, ear, or mouth might be observed during fetal ultrasound scans.
