A Cephalometric Analysis of Hemifacial Microsomia

Objective: The purpose of the present study was to analyze the facial asymmetry systematically using the cephalometric method, so as to demonstrate the difference on both sides of Hemifacial microsomia(HFM) in adult. Study Design: Twelve adults of HFM were chosen, and the muscles and velocity of conduction of facial nerve were measured using the electromyographic machine. We collected all the patients' cephalometric radiographs in the anterior and posterior projections and analysed the size and symmetry of orbit, maxilla and mandible.
