Management of developmental asymmetrical facial growth.

Several aspects of the management of developmental asymmetrical facial growth are addressed. The abnormality is further defined. Methods of examination and assessment of records are discussed. A complicating factor has been the adoption of too many classification systems. With three-dimensional imaging techniques (computed tomography scan and stereophotography) great advancement has been made in efforts at describing the range of variation. Hemifacial microsomia patients are best treated in multidisciplinary centers by competent specialists with the necessary expertise and skills. The procedure followed in the craniofacial center in Rotterdam is described and discussed in relation to current treatment strategies. The success of the treatment of the asymmetrical facial growth depends on the original abnormality, on secondary abnormal development, and on orthodontic and surgical intervention. International cooperation is necessary to compile sufficient statistical data for a scientific evaluation of treatment results and to improve the effectiveness and the efficiency of treatment.
