Synthes External MVMD is intended for use as a bone stabilizer and lengthener for conditions such as mandibular hypoplasia or post-traumatic defects of the mandible, where gradual bone distraction is required. The device is ideal for treating any form of congenital mandibular hypoplasia, such as Hemifacial Micorsomia, Treacher Collins Syndrome, Nagers Syndrome, Pierre Robin Syndrome, Goldenhar Syndrome, Apert Syndrome, and Crouzon Syndrome. Synthes External MVMD is also ideal for treating hypoplasias of an acquired origin such as from post-traumatic growth disorders associated with injury to the temporomandibular joint, temporomandibular ankylosis, and segmental loss of bone.
