Goldenhar syndrome, also known as oculo-auriculo-vertebral (OAV) syndrome, is a congenital condition that primarily affects the development of the face and other structures in the head and neck. This rare syndrome is characterized by a wide range of physical abnormalities and can vary in severity from person to person. Some common features and characteristics of Goldenhar syndrome include:
1. Craniofacial abnormalities: Individuals with Goldenhar syndrome may have facial asymmetry, with one side of the face appearing underdeveloped or smaller than the other. This can affect the eye, ear, and jaw on the affected side.
2. Ocular abnormalities: Eye problems may include microphthalmia (abnormally small eye), anophthalmia (absence of the eye), strabismus (crossed eyes), or other visual impairments.
3. Ear abnormalities: Ear issues are common in Goldenhar syndrome and can involve underdeveloped or malformed external ears (auricles) and hearing loss.
4. Jaw and oral cavity abnormalities: The lower jaw (mandible) may be smaller on the affected side, leading to dental and bite problems. Cleft lip and/or cleft palate can also be present in some cases.
5. Vertebral anomalies: Abnormalities of the spine, such as vertebral fusion or scoliosis, may occur.
6. Cardiac defects: Some individuals with Goldenhar syndrome may have congenital heart defects, although these are less common.
7. Kidney and lung anomalies: In some cases, there may be kidney or lung abnormalities.
8. Limb abnormalities: Rarely, limb abnormalities, such as extra fingers or toes, may be present.
The exact cause of Goldenhar syndrome is not fully understood, but it is believed to be related to disruptions in early fetal development during the first trimester of pregnancy. It is not an inherited condition but rather occurs sporadically.
Treatment for Goldenhar syndrome is typically individualized, based on the specific features and needs of each affected individual. It may involve a multidisciplinary approach, including surgery to correct facial and jaw abnormalities, hearing aids or cochlear implants for hearing loss, and other interventions to address associated health issues.
The outlook for individuals with Goldenhar syndrome can vary widely, depending on the severity of their condition and the specific medical issues they face. With appropriate medical care and support, many individuals with Goldenhar syndrome can lead fulfilling lives and achieve their potential. Early intervention and a supportive medical team can make a significant difference in improving the quality of life for individuals with this syndrome.
