ABSTRACT
<p><b>OBJECTIVE</b>To study the application of distraction osteogenesis (DO) of the mandibular ramus in hemifacial microsomia.</p><p><b>METHODS</b>From 1999 to 2006, 15 patients with hemifacial microsomia were treated with DO of the ramus, including 12 cases of children and juveniles, 3 cases of grown-ups. Maxillary Le Fort I osteotomy, unilateral sagittal split ramus osteotomy, genioplasty and free scapular flaps were selected to perform on the first or secondary stage of treatment.</p><p><b>RESULTS</b>Successful distraction was achieved in all patients with an average distraction distance of 21.25 mm. The distractor was removed after consolidation proved by clinical examination and X-ray. Facial appearance and and occlusal relationship were improved greatly. The occlusal plane was almost normal. There was no infection, malunion or permanent injury of inferior alveolar nerve.</p><p><b>CONCLUSIONS</b>DO of the ramus is very effective for the correction of severe hemifacial microsomia. It has much better therapeutic effect than traditional orthognathic procedures.</p>
