Goldenhar syndrome

Goldenhar syndrome, also known as oculo-auriculo-vertebral (OAV) spectrum or hemifacial microsomia (in its broader classification), is a congenital condition characterized by incomplete development of structures arising from the first and second branchial arches during embryonic development. It predominantly affects the face, ears, eyes, and spine, typically in an asymmetric fashion. The condition is present at birth and represents one of the most common craniofacial malformations after cleft lip and palate. Key clinical features include hemifacial microsomia (underdevelopment of one side of the face), microtia or anotia (small or absent external ears) often with preauricular skin tags or pits, epibulbar dermoids (benign growths on the eye surface), and vertebral anomalies such as hemivertebrae or fused vertebrae. Hearing loss, both conductive and sensorineural, is common due to malformations of the outer and middle ear. Mandibular hypoplasia (underdeveloped jaw) can lead to facial asymmetry and dental malocclusion. Some patients may also have cardiac defects, renal anomalies, and, less frequently, central nervous system abnormalities. The severity is highly variable, ranging from mild facial asymmetry to significant functional impairment. There is no cure for Goldenhar syndrome, and management is multidisciplinary, involving craniofacial surgeons, otolaryngologists, ophthalmologists, audiologists, orthodontists, and speech therapists. Treatment is tailored to the individual's specific manifestations and may include surgical reconstruction of the ear and jaw, removal of epibulbar dermoids if they affect vision, hearing aids or bone-anchored hearing devices, and orthodontic interventions. Early intervention for hearing loss is critical to support speech and language development. Regular monitoring for associated cardiac and renal anomalies is also recommended.
