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

Abstract

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.
