Hemifacial Microsmia is the second most common defect affecting the face behind cleft lip and palate. The most common structures affected are the ear and jaw, but many other structures in the face may be involved including the upper jaw, mouth, and facial nerves.
We are unsure what causes the maldevelopment in hemifacial microsomia, but genetic and environmental factors may play a large role. The incidence of hemifacial microsomia is likely under-reported due to the wide variations of severity, but may be between 1: 5,000 to 1: 25,000 new births.
Symptoms of hemifacial microsomia may lead to occlusal issues, development of sleep apnea, swallowing problems and hearing deficits to hearing loss.
Surgical intervention to treat degrees of hemifacial microsomia may be as simple as removing a skin tag in front of the ear to performing jaw surgery to correct sleep apnea or malocclusion.
