Resorbable distraction of the midface and orbits and frontal bone: Indications and operative technique

Distraction osteogenesis has been widely accepted for treatment of facial skeletal deformities. The synthesis of distraction technology and new resorbable materials has resulted in a new class of distraction devices. These single-stage distraction devices have been successfully applied to severe facial skeletal deformities. Simultaneous advancement of the midface and orbits-the monobloc procedure-is necessary in cases involving coronal synostosis and midface hypolasia resulting in malocclusion exophthalmus, obstructive apnea, and frequently increased intracranial pressure. The application of a resorbable midface-orbital-frontal (MOF) distractor for graduated monobloc distraction is presented with indications and techniques.
