title: The external ear, mandible and other components of hemifacial microsomia.
abstract: This report is based on an analysis of 100 patients with the unilateral form of HFM, in which the patients presented no other known craniofacial or extracranial malformations. The analysis was based on a three level gradation of severity of the external ear and the mandible, resulting in nine different combinations. This analysis of selected components of the syndrome clearly illustrates the phenotypic heterogeneity within the sample. It also follows that treatment should be guided by the number and severity of the affected components.
