Overview
Hemifacial microsomia is the second most common facial birth defect behind cleft lip and palate, affecting one in every 3,500 to 4,000 births. Hemifacial microsomia is a congenital condition in which the tissues on one side of the face are underdeveloped. It primarily affects the ear, mouth, and jaw areas, though it may also involve the eye, cheek, neck, and other parts of the skull, as well as nerves and soft tissue. In 10 to 15 percent of cases, both sides of the face are affected, oftentimes asymmetrically.
Children with hemifacial microsomia need ongoing medical care, including multiple surgeries. But once they reach early adulthood, they likely won’t need any more procedures. Long-term follow-up may be necessary to check for issues that come back or worsen over time. Hearing aids and implants may need adjusting.
Physical challenges and the psychological effects of looking different can impact your child’s emotional health. Seeking support through counseling is essential in helping your child develop coping strategies.
Causes
Symptoms can range from mild to severe and usually involve the underdevelopment of one or more facial features. Hemifacial microsomia affects everyone differently, and the degree of involvement can vary. One of the ways clinicians describe and assess the severity of hemifacial microsomia is the OMENS classification. The OMENS classification examines the function and appearance of each of the following, looking for characteristics commonly associated with hemifacial microsomia:
- Orbit (eye socket): small and underdeveloped eyes with impaired vision; absent or unformed eye; growths on the eye; one eye appearing smaller than the other, but with normal vision
- Mandible (the jaw bones): underdeveloped upper and lower jaw on one side; crooked jaw; missing, misaligned or overcrowded teeth; cleft lip and/or cleft palate; limited opening or closing of the mouth
- Ear: small skin tags; misshapen or missing external ear; absent or abnormal development of the ear canal resulting in partial or total hearing loss
- Nerves: ranging from mild weakness to partial or full facial paralysis
- Soft tissues (skin, muscle, fat, tendons and ligaments): flattened forehead or cheekbone, unequal cheek fullness, asymmetrical mouth with lateral cleft
Most children with hemifacial microsomia have facial anomalies but no other major medical issues. In some cases, babies born with hemifacial microsomia may also have other health problems such as malformed vertebrae, heart defects or abnormally shaped kidneys.
Diagnosis and Tests
Healthcare providers typically start with a physical exam. They usually diagnose the condition shortly after birth. In some cases, they might detect it before birth using prenatal ultrasound or MRI (magnetic resonance imaging).
Your healthcare provider may need to run additional imaging tests to diagnose hemifacial microsomia, like:
- X-rays
- CT scans (computed tomography scans)
Management and Treatment
Treatment for this condition depends on the severity of involvement. Children with hemifacial microsomia usually need surgery to repair or reconstruct their facial features. The type and timing of these procedures depend on your child’s needs. In infancy, the focus of treatment is to make sure your baby is breathing and feeding well. In childhood and adolescence, the goal of treatment is to improve the function and appearance of the face. It’s often necessary to delay procedures or do them in multiple stages as your child grows.
Surgical treatments
Surgical treatments for hemifacial microsomia include:
- Ear, nose and throat surgery
- Facial plastic surgery
- Eye surgery
- Maxillofacial surgery
- Oral surgery
- Plastic surgery
Neonatal surgery
If your newborn has breathing difficulties or is unable to nurse, your healthcare provider may treat your baby’s hemifacial microsomia immediately after birth. The most common procedures done after delivery include:
- Tracheostomy, an incision in your baby’s neck and windpipe to aid breathing
- Tube feeding, which gives your baby nutrition if they’re unable to nurse
Nonsurgical treatments
In addition to surgical treatments, your healthcare provider may recommend these nonsurgical therapies:
- Braces and other teeth-straightening devices
- Hearing aids for mild hearing loss
- Speech therapy to address challenges with swallowing and speaking
During follow-up visits, diagnostic testing may be done. The goal of continued monitoring is to help spot any irregularities in growth or development and to address health issues as they develop, optimizing long-term outcomes for your child.
