What is Goldenhar Syndrome

Goldenhar syndrome, also known as oculo-auriculo-vertebral (OAV) spectrum, is a rare congenital condition characterized by abnormal development of the eyes, ears, and spine. While the severity varies widely among individuals, the condition is primarily defined by incomplete development of one or both sides of the face and associated skeletal or organ involvement.

What are the primary characteristics of Goldenhar syndrome?

Goldenhar syndrome affects multiple systems, most notably the craniofacial region. Clinical presentation is highly variable, meaning no two individuals experience the condition in exactly the same way. The most common physical features of Goldenhar syndrome include:

• Craniofacial asymmetry: Underdevelopment of the cheekbones, jaw, or facial muscles.


• Ear abnormalities: Small or missing external ears (microtia), ear tags, or hearing loss.


• Ocular findings: Benign growths on the surface of the eye (epibulbar dermoids) or eyelid notches.


• Vertebral defects: Abnormalities in the cervical (neck) vertebrae, such as fused or misshapen bones.

How common is Goldenhar syndrome and who does it affect?

The prevalence of Goldenhar syndrome is estimated to range between 1 in 3,500 and 1 in 25,000 live births. It is slightly more common in males than in females, with a ratio of approximately 3:2. While Goldenhar syndrome is recognized globally, there is no evidence that it is restricted to specific geographic regions or ethnic groups. Symptoms are present at birth, making this a congenital condition that is often identified during newborn screenings or shortly thereafter.

What causes Goldenhar syndrome?

The underlying mechanism of Goldenhar syndrome is not fully understood, but it is generally considered a developmental field defect. In most cases, Goldenhar syndrome occurs sporadically, meaning it is not inherited from parents. Researchers believe it may result from a combination of genetic and environmental factors during early pregnancy that disrupt the development of the first and second branchial arches, which form the tissues of the face and neck. While some rare familial cases have been reported, the vast majority of individuals with the condition have no family history.

How is Goldenhar syndrome differentiated from similar conditions?

Because it is part of the OAV spectrum, Goldenhar syndrome can overlap with other conditions like Treacher Collins syndrome or Hemifacial Microsomia. Key factors that help clinicians distinguish this syndrome include the specific combination of epibulbar dermoids (eye growths) and vertebral column anomalies. At DiseaseMaps.org, we have 173 members who share their unique experiences, highlighting that while the clinical diagnosis is based on physical findings, the functional impact on daily life is deeply personal and requires a multidisciplinary approach.

Next steps

• Consult with a clinical geneticist to discuss individual health assessments and family planning.


• Schedule appointments with a multidisciplinary team, including an otolaryngologist (ENT), ophthalmologist, and craniofacial surgeon.


• Join the Goldenhar syndrome community on DiseaseMaps.org to connect with others and share experiences regarding long-term care management.


• Request a referral to a pediatric feeding clinic or speech pathologist if your child faces challenges with jaw development or speech.
