Hemifacial microsomia managed by distraction osteogenesis: A clinicoradiological report.

Hemifacial microsomia (HFM) is a congenital malformation in which there is hypoplasia of hard and soft tissues on one side of the face. It is considered the second most common congenital syndrome of the head-and-neck region. The hypoplasia manifests in all the structures derived from the first and second branchial arches and therefore, growth and development of these structures is affected in this condition. The present case is a variant of HFM in a 5-year-old Indian male child, which has been diagnosed based on clinical and radiological findings and managed successfully by surgical technique known as distraction osteogenesis.
