title: Nonsurgical Treatment of Hemifacial Microsomia: A Case Report.
abstract: BACKGROUND
  Hemifacial microsomia (HFM) is a birth defect involving craniofacial structures derived from the first and second branchial arches. Although it is a relatively uncommon malformation, it is the second most common craniofacial birth defect after cleft lip and palate (CL/P).
  
  
  METHODS
  This is a case report about the successful orthodontic treatment of a patient with mild hemifacial microsomia (HFM), using a non-surgical orthopedic and orthodontic treatment approach. The aim of this approach was to make the best noninvasive modality to treat HFM. A 7-year-old boy with a mild HFM presented with a convex profile and slight chin deviation. Orthopedic treatment performed using a hybrid functional and high pulls headgear. Treatment continued by fixed orthodontic straight wire appliance to achieve perfect occlusion.
  
  
  CONCLUSIONS
  Excellent esthetic and functional results achieved; total treatment duration was about 72 months.
