Have you ever noticed that sometimes one side of a baby's face is a little different than the other, maybe a little different? Or the ear is in a slightly different place, or the cheek doesn't seem to be formed properly. It's normal for a parent to feel a little scared and worried when they see something like this. That's the condition we're going to talk about today, called Hemifacial Microsomia. Don't worry, let's talk about this in detail.
What is Hemifacial Microsomia?
Simply put, Hemifacial Microsomia is a congenital condition . It occurs when parts of one side of a baby's face, such as the ears, mouth, and jawbone, do not develop properly compared to the other side. Think of it as a little bit of 'elements' missing on one side when the face is forming. This is sometimes called Craniofacial Microsomia.
Most of the time, this only affects one side of the face. However, very rarely, this condition can affect both sides of the face. In that case, we call it Bilateral Hemifacial Microsomia.
This condition can affect the following parts of the face:
- Cheekbones
- Eyes
- The outer part of the ear and the middle ear
- Facial nerves (these are what control our facial expressions and laughter)
- Mandible
- Facial muscles
- Neck
- Skull
- Teeth
Although very rare, sometimes Hemifacial Microsomia can be accompanied by problems in other body systems, such as the heart, kidneys, chest bones (ribs), and spine.
Statistically, this condition affects about 1 in 3,000 to 5,600 babies born. It is the second most common congenital anomaly of the face, after cleft lip or cleft palate.
What could be the symptoms?
The symptoms of this condition can vary greatly from person to person. Some people are only slightly affected, while others are more severely affected . This means that the nature and severity of these symptoms vary depending on how much of the facial area has developed.
These are some of the most common symptoms:
- Microtia: This is a condition in which the ear is small, misaligned, or abnormally shaped. It can even be completely missing.
- Hypodontia: Some teeth never come in. That is, the teeth do not develop from the beginning.
- Facial paralysis due to facial nerve weakness: It may be difficult to do things like close the eye properly on the affected side, smile, or frown.
- Skin tags: These are small, extra pieces of skin that are usually found near the ear, sometimes on the cheek.
- Smallness of one eye (Microphthalmia): The affected eye may appear smaller compared to the other eye. The eyeball itself may also be smaller.
- Uneven smile: Because the muscles and nerves are not properly developed, the two sides of the face may not be equal when smiling.
These are the main symptoms that are seen. But as I said before, not everyone has all of these symptoms, and the severity of the symptoms that are present varies greatly.
Why is this happening? What are the reasons?
In fact, experts still don't know the exact cause of Hemifacial Microsomia. They believe that the condition is caused by something that disrupts the development of the fetus during the first six weeks after conception (that's the first month and a half of pregnancy). Remember, it's during those first few weeks that parts of the baby's face begin to form. That's when something, perhaps a slight lack of blood supply, can go wrong.
Researchers have yet to pinpoint any specific genes or environmental factors that are linked to this. That means don't assume it's because of something the mother did or didn't do during pregnancy. This is no one's fault.
However, since some families have more than one person with the condition, they suspect that it may be hereditary . But there is not enough research to confirm that yet.
What complications can occur due to this condition?
In addition to facial changes, children with Hemifacial Microsomia may experience some other complications. It's good to be aware of these as well:
- Hearing loss: This problem can occur, especially if the ear and ear canal are not developed properly. Sometimes, hearing may be completely lost on one side.
- Malnutrition due to difficulty eating: If the lower jaw is not properly aligned or there are problems with the teeth, it may be difficult for the baby to suckle, eat food later, and chew. This can lead to weight loss and stunted growth.
- Oral health conditions: Teeth grinding, crooked teeth, and cavities are common.
- Speech disorders: It can be difficult to pronounce words and speak clearly due to problems with facial muscles, jawbone, and palate.
- Vision issues: Vision can be affected by things like microphthalmia (small eye) and other eye problems.
- Breathing problems: Sleep apnea can occur, especially if the lower jaw is very small and the nasal passages are narrow.
It is very important to be aware of these things and seek the necessary medical advice and treatment.
How do you diagnose this?
Doctors usually first do a thorough physical exam of the baby. In many cases, this condition can be diagnosed as soon as the baby is born, because the facial changes, especially in the ears and chin, are clearly visible.
However, in some cases, prenatal ultrasounds or MRI (Magnetic Resonance Imaging) tests performed before the baby is born, that is, while it is still in the mother's womb, can provide a clue about this condition. However, this does not always happen.
To confirm the diagnosis of Hemifacial Microsomia, to determine the extent of the damage, and to determine exactly which parts of the brain are affected, doctors may perform other imaging tests . For example:
- X-rays: Check the condition of the facial bones.
- CT scans (Computed Tomography scans): These can produce a clearer, three-dimensional image of the bones and soft tissues of the face. This is very helpful in planning surgery.
These tests can provide a clear picture of the facial bones, muscles, and nerves, which is a great help in planning treatment.
How is it treated?
The treatment for this condition depends on how severely it affects the child. Children with hemifacial microsomia usually need surgery to repair or reconstruct parts of the face.
What these surgeries are and when they are performed varies from child to child, depending on the child's needs, age, and the parts affected.
It's very important that when the baby is young, that is, in infancy , the main goal of treatment is to help the baby breathe and feed well . These are the basics.
Then, as the child gets older, that is, during childhood and adolescence , the goal of treatment is to improve facial function and appearance . That is, to improve facial symmetry and appearance while making things like talking, eating, and smiling easier.
Most of the time, these surgeries cannot be done all at once. As the child grows, they have to be done in multiple stages , depending on how the facial bones develop. Some surgeries may have to be postponed as the child grows. This is a time-consuming process that requires patience.
Surgical treatment
Surgical procedures for Hemifacial Microsomia may include the following. These are performed by a team of specialist doctors:
- Ear, nose and throat surgery (ENT surgery): especially ear reconstruction and hearing implants.
- Facial plastic and reconstructive surgery: Restore facial symmetry and appearance. Fat grafting or other tissue grafting to areas where soft tissue is lacking.
- Eye surgery / Ophthalmic surgery: If the eyes are small or there are problems with the eyelids, repair them.
- Maxillofacial surgery / Orthognathic surgery: To correct the length and position of the lower jaw, upper jaw, cheekbones, etc. Sometimes distraction osteogenesis techniques are used.
- Oral surgery: Extraction of teeth if they have been pulled, removal of extra teeth.
All of this is done to help the child live as normally as possible.
Surgeries performed on newborns
If a newborn baby has breathing difficulties or is unable to nurse , doctors may begin treatment as soon as the baby is born. These can be life-saving measures.
There are two common methods that can be done immediately after the baby is born:
- Tracheostomy: This involves making a small incision in the baby's neck and windpipe and inserting a tube to help them breathe. This is done if the airway is blocked.
- Tube feeding (Nasogastric tube or Gastrostomy tube): If the baby is unable to suckle on their own, a tube is used to provide nutrition. This can be a tube that goes through the nose into the stomach (NG tube), or a tube that goes directly into the stomach (G-tube).
Non-surgical treatments
In addition to surgery, doctors may also recommend non-surgical treatments such as these. These are also very important to improve the child's quality of life:
- Braces and other orthodontic devices: These are used to correct the position of the jaws if teeth are pulled.
- Hearing aids: If you have hearing loss, you may need to use cochlear implants or bone-anchored hearing aids (BAHA).
- Speech therapy: Helps with swallowing and speaking difficulties. This helps to pronounce words clearly and strengthen facial muscles.
All of these things come together to make a child's life easier. This requires the support of many people, including doctors, surgeons, dentists, speech therapists, and audiologists.
Can Hemifacial Microsomia be prevented?
Unfortunately, this condition cannot be prevented . Because, as I mentioned before, researchers still don't know exactly what causes it. Although it is suspected that there may be a genetic link, that too has not yet been definitively discovered.
It's very important to understand that if your baby has Hemifacial Microsomia, it's not because of something you did or didn't do during pregnancy . Don't feel bad about it, and don't blame yourself.
What's the outlook with this situation?
In most cases, this condition does not limit a child's life expectancy . This means that a child with this condition can live a normal life span, just like a child without it.
However, Hemifacial Microsomia can affect a child's quality of life . As children grow older, they have to face the challenges that come with knowing that they look different from others.
Even if the surgery is successful, these children may have difficulty with things that other children can do very easily, such as eating, talking, and sleeping. So we need to be careful about that too.
How do I take care of my child?
Children with Hemifacial Microsomia require ongoing medical care, which may include multiple surgeries. However, by the time they reach early adulthood, they may no longer need surgery.
However, long-term follow-up may be necessary to see if problems recur or if existing problems get worse over time. For example, things like hearing aids and implants may need to be adjusted from time to time. Dental health should also be taken care of regularly.
Just like physical challenges, the psychological effects of being different can affect a child's emotional health. Therefore, it is important for the child to receive counseling to help them develop coping strategies.
As a parent, I understand that you want everyone to see your child the way you do. It's normal to feel scared when your child is old enough to go to school. Sometimes children, especially those they think are different from them, can be mean and make fun of.
As soon as your child is old enough to understand, talk openly with them about their condition . Making this kind of conversation a regular occurrence will not only empower them, but also help them understand that their facial differences do not define who they are.
Surgery can correct many of the physical features of Hemifacial Microsomia. In addition, talk therapy can help your child learn to express their feelings and work well with others in society. Ask your doctor for more information and help. They are there to help you.
What is the difference between Hemifacial Microsomia and Goldenhar Syndrome?
Goldenhar Syndrome is a rare congenital condition. It is also called Oculoauriculovertebral spectrum (OAVS).
Hemifacial Microsomia may actually be a feature of Goldenhar Syndrome. That is, in addition to the features of Hemifacial Microsomia, a person with Goldenhar Syndrome may also have non-cancerous tumors in the eyes (epibulbar dermoids) or spinal abnormalities (e.g., fusion of the vertebrae). There may also be problems with the heart or kidneys.
Simply put, Hemifacial Microsomia is a condition that primarily affects the development of the face. Goldenhar Syndrome is a condition that can have a wider range of symptoms, affecting other parts of the body as well. Not everyone with Hemifacial Microsomia has Goldenhar Syndrome, but many people with Goldenhar Syndrome have symptoms of Hemifacial Microsomia.
