Goldenhar syndrome

Goldenhar-Gorlin syndrome; ocular-auricula-vertebral anomaly; first and second branchial arch syndrome.

INCIDENCE

  • Only in the United States have there been any studies conducted on the prevalence of this illness. According to one research, the incidence rate in the Midwest of the United States was one out of every 5600 live births. A subsequent investigation found that the incidence rate in the United States was one in per 26 000 live births. It would appear that boys are affected by this syndrome at a rate that is marginally higher than that of girls.

CAUSATION

  • There appears to be a variety of inheritance patterns, and it would appear that either an autosomal dominant or an autosomal recessive inheritance is a possibility. Even within the same family, there is a large amount of variation in the impact of the manifestations of this condition. Because of this, proper diagnosis and the identification of inheritance patterns are both made more challenging.
  • An examination using ultrasound during pregnancy has the potential to identify significant ear problems if they are present. Other skeletal anomalies, such as a tiny lower jaw, could also be seen on the patient's x-rays.

CHARACTERISTICS

  • Ears: Abnormalities in the anatomy of both the external and the middle ear are among the most noticeable and crucial aspects. These abnormalities can be found in both the external ear and the middle ear. There is a wide range of variation in the size and form of the external ear, which can range from absolutely no external ear at all to a pinna that is significantly deformed. This condition can affect any ear or both ears.
  • The ossicles, which are very little bones that are essential for regular hearing, can also be very small or malformed. The middle ear, which contains the ossicles, can also be very small. In the event that these ossicles are underdeveloped or have an abnormal shape, sound will not be carried appropriately into the nerves of hearing, which will result in conductive hearing loss.
  • In addition to these irregularities in the ear, the facial nerve can occasionally run a course that is aberrant as well. The Eustachian tube, which is located behind the throat and connects the middle ear to the back of the throat, can also be deformed. All of these issues can contribute in some way to the hearing loss.
  • Asymmetry of the face is another trait that can be observed in well over half of the infants who are born with this disease. As the baby grows older, the asymmetry becomes more noticeable, and by the time the child is approximately four years old, the unique form of the child's face is clearly apparent.
  • A cleft palate, which may or may not be accompanied by a cleft lip, is one of the congenital defects that can contribute to a distinctive facial appearance.
  • A chin that is thin and drooping away from the face is another possible trait. In the first few days of life, concerns should be raised if this condition is present because it can make feeding difficult.
  • There is a correlation between having small eyes and the real eyelids being narrower, which gives the impression that the eyes are even smaller. About one-third of children diagnosed with Goldenhar syndrome develop growths in their eyes that are pinkish or yellowish in color and frequently contain a significant amount of fatty tissue. These have the potential to reach a diameter of 10 rom when fully grown.
  • When they reach this big, it may become difficult to see through them.
  • Other skeletal abnormalities can be present and can range all the way from abnormally shaped vertebrae, which can eventually lead to scoliosis, to anomalies in the forearm and thumbs. Other skeletal abnormalities can be present and can range all the way. (These more recent characteristics are suggestive of the anomalies observed in both the CHARGE and the VATER relationships. These two 'associations' of anomalies include deficiencies in the area of the forearm that are fairly comparable to one another. On the other hand, there is no link between these disorders and the Goldenhar syndrome.)
  • There is a higher incidence of heart abnormalities in these babies compared to other babies. There are a variety of reports concerning the frequency of this kind of anomaly. According to the findings of some researchers, the prevalence of Goldenhar syndrome in newborns may be as high as 58%. It's been said that ventricular septal defects are one of the most prevalent of these heart anomalies. [Citation needed]
  • There is a possibility of a learning handicap present in one or more of the children who have this syndrome. Additionally, some children who have extremely misshapen faces can have significant mental health issues.

MANAGEMENT IMPLICATIONS

  • If a baby is born with a small lower jaw, eating can be difficult for them in their first few days of life ( cf Pierre-Robin syndrome). If there is also a cleft palate, whether or not there is also a cleft lip linked with it, this will add to the challenges involved with feeding.
  • In the early stages, it is possible that tube feeding will be required to guarantee appropriate nutrition. In the most extreme circumstances, surgical intervention may be required in order for meals to be administered directly into the stomach. Additionally, the odd face characteristics may cause breathing difficulties, particularly when the individual is sleeping. A small lower jaw can make it possible for the tongue to slide back into the throat, which can make it difficult to breathe. To prevent this from happening, babies should always be placed to sleep on their sides.
  • To reduce the likelihood of a child developing speech delays later in life, it is essential that hearing loss be identified and thoroughly evaluated at the earliest feasible age. In most cases, one to two years is considered the absolute maximum age for the development of speech and language skills. However, before to this period, the infant is listening to other people, most notably his or her parents, in order to gain information regarding varied sound patterns. Any hearing loss at either of these crucial periods can result in a significant delay in the child's capacity to communicate verbally. Speech therapy is beneficial and frequently required for a person to be able to communicate in a way that is clear and easy to understand once the hearing loss has been detected and treated to the best of one's ability. Because of the peculiar characteristics of their facial features, children who have Goldenhar syndrome may have trouble articulating their words, in addition to the challenges that are caused by hearing loss. Speech therapists have a wide variety of strategies at their disposal to combat each of these challenges.
  • Eyes: if the normal growths are present in the eye region, they need to be removed before their further expansion makes it impossible to see out of those eyes. Scar tissue is something that will invariably form after surgery, and this can unfortunately have a negative impact on a person's vision after it has been removed.
  • If the cleft palate defect is present, surgical correction of the condition will be required. In the event that the other facial asymmetries are severe and treatable via surgical means, then it is possible that surgery will be required to correct them.
  • After teeth have emerged, it is essential to begin receiving dental care immediately. Because the face is not symmetrical, the teeth will not always come together in the correct way. As a result, orthodontic treatment will be required.
  • If the child does have heart problems, they will need to be evaluated, and depending on the type of abnormality and the consequences it is having on the child, they may require treatment.
  • A routine developmental evaluation will need to be performed at regular intervals in order to verify the mental capacity of the child, and this assessment will need to be continued while the child is in school. By doing so, problems in any particular area can be singled out, and appropriate assistance can be provided.
  • If the facial deformation is very noticeable, it may cause a person to experience emotional difficulties, particularly throughout the teen years. The effects of such problems should be mitigated to a significant degree by the provision of sensitive counseling as well as support from friends and family. Joining a support group with other individuals who are going through something similar is another effective way to get aid.

THE FUTURE

  • There is no limitation placed on lifespan unless the heart problems are of such a severity that they cannot be treated. If you have a significant hearing loss, your options for a career may be more restricted. A facial deformity may also be a hindrance that prevents a person from pursuing jobs that put them in the public eye.
  • It is recommended to seek genetic counselling before beginning pregnancy planning.
