Goldenhar disease, also known as oral-oculo-vertebral dysplasia syndrome, is a rare genetic disorder characterized by abnormal development of the facial structures, ears, eyes, and spine. This pathology is classified as a disorder of embryonic development associated with the influence of various factors during the early gestational period. The syndrome is characterized by asymmetric development, related to both the location of organs and their functions. The most common anomalies are in the area of the auricle (microthyma), as well as the absence or underdevelopment of one of the eye arches. It is important to note that Goldenhar disease can manifest itself in different forms, and the severity of symptoms varies from case to case, which complicates diagnosis and treatment.
History of the disease and interesting historical facts
The first mention of Goldenhar disease dates back to 1952, when a German surgeon, Dr. Alfred Goldenhar, described several cases of anomalies similar to the colorful spectrum of current pathology manifestations. Since then, a lot of clinical data has been collected about this disease, which marked the beginning of its further study. Interestingly, until the 1970s, the disease was considered an isolated clinical syndrome, but later other cases became known that indicated more extensive genetic links with a number of other diseases. Modern research confirms that the syndrome can also be part of a syndromic complex that includes various anomalies of other organ systems.
Epidemiology
According to statistics, the prevalence of Goldenhar disease is approximately 1 case per 3-5 thousand newborns. The pathology occurs in both men and women with equal frequency. The reasons for such a rare occurrence may vary depending on the region and ethnicity, but in general, this disease is considered rare, which makes it difficult to fully understand its epidemiology. It is known that in some populations the incidence may be higher, which requires additional study. A comprehensive analysis of state and regional medical registries can provide additional data on the frequency of occurrence and its dynamics.
Genetic predisposition to this disease
In recent decades, researchers have identified a number of genes and mutations associated with Goldenhar disease. The most notable are mutations in genes responsible for the formation and development of structures that form the ear, eye, and facial bones. Genetic analysis shows that 30-40% patients have mutations in genes belonging to the horizontal cell transposon group. In addition, there are frequent cases of similar abnormalities in family members, indicating that the syndrome may be hereditary. However, not all forms of the disease have a strong family history, indicating that the disorder may occur sporadically.
Risk factors for the development of this disease
Factors that contribute to the development of Goldenhar's disease can be divided into physical and chemical. Physical factors include:
- Effects of radiation on pregnant women.
- Infections during pregnancy, such as rubella or cytomegalovirus infection.
Chemical factors may include:
- Use of certain medications, such as antitetragenic drugs.
- Contact with toxic substances such as mercury or lead.
Other possible associated factors may include a positive family history of other genetic disorders and environmental factors in the region of residence.
Diagnosis of this disease
Diagnosis of Goldenhar's disease is based on clinical examination, which includes studying the main symptoms. The main symptoms of the disease include:
- Complications in the structure of the ears, including microthymia.
- Abnormalities in the eye area, such as underdeveloped eyelids.
- Vertebral anomalies.
Laboratory tests may include genetic testing to detect mutations. Radiological tests, such as X-rays or MRIs, are needed to detect structural abnormalities, especially in the skull and spine. Other diagnostics include the use of ultrasound early in pregnancy to detect abnormalities in the fetus. Differential diagnosis includes consideration of other syndromes, such as Van der Woude syndrome and Patau syndrome, which have similar presentations.
Treatment
Treatment of Goldenhar disease is primarily multidisciplinary and depends on the severity of symptoms and organ involvement. General treatment is aimed at correcting structural abnormalities and improving the patient's quality of life. Pharmacological treatment may include the use of anesthetics and anti-inflammatory drugs in the postoperative period. Surgical treatment is aimed at correcting abnormalities of the ear, eye, or skull, as well as correcting spinal curvatures. In addition, other treatments such as orthopedic rehabilitation may be used to improve functional capabilities.
List of medications used to treat this disease
- Pain relievers (eg, Ibuprofen)
- Anti-inflammatory drugs (eg, Diclofenac)
- Antibiotics to prevent infections after surgery (eg, Amoxicillin)
- Drugs to improve blood circulation (eg, Pentoxifylline)
Disease monitoring
Monitoring the disease requires regular control, especially during the period of growth and development of the child. It is important to conduct control examinations every 6-12 months to assess the effectiveness of treatment and the dynamics of the patient's condition. The prognosis with adequate treatment is favorable in most cases, but complications are possible, such as relapses of anomalies or concomitant diseases.
Age-related features of the disease
The symptoms of Goldenhar disease can vary significantly depending on the patient's age. Newborns have the most pronounced manifestations, which allows for timely diagnosis. In older age, new anomalies may arise, including skeletal system development disorders. The approach to treatment and monitoring will vary depending on age, which requires an individual approach to each patient.

Advice from Dr. Oleg Korzhikov:
In the presence of Goldenhar disease, the doctor must take into account the individual characteristics of the patient. It is important to request a full medical examination at the initial stages to determine the extent of pathologies. Early diagnosis and joint treatment by a multidisciplinary team of specialists can significantly improve the quality of life of patients. Do not forget about psychological support, both for children and their families, since the emotional aspect is also of great importance in the rehabilitation process.
