The most common orthopedic treatments provide vertical stimulation of the maxillary process in the affected side. Orthodontic approaches are mainly applied for vertical correction and stabilization of the occlusal plane. Other treatment options include orthognathic surgery, osteogenic distraction, temporomandibular reconstruction and grafting. It is recommended that prospective clinical randomized controlled studies be conducted using homogeneous pediatric groups with long-term follow-up, to establish recommended evidence-based methods for treating each set of hemifacial microsomia symptoms.
