Abstract
Hemifacial microsomia (HFM) is one of the most common congenital craniofacial soft and hard tissue deformities, manifesting as a unilateral underdevelopment of anatomical structures arising from the first and second brachial arches. The most salient feature is the underdevelopment of the mandible, particularly the ramus and condyle. Developmental disturbances at various times can lead to numerous presentations in size and function, which might require different treatment options. Conventional therapy for asymmetric patients with severe forms of HFM has been unilateral distraction osteogenesis. However, there has been noted relapse into facial asymmetry due to contraction of the bony segments and a lack of downward growth. With regard to avoiding such complications, we have elected to utilize both the distraction osteogenesis method and traditional orthognathic surgery, allowing us to better control vector movement of the maxillary and mandibular segments. It is our goal that by demonstrating this technique on such an extreme case of HFM, we can show that both methods can be used simultaneously to successfully correct this deformity, whereas each one individually might not have.
