Skeletal stability after correction of maxillary hypoplasia by the Glasgow extra-oral distraction (GED) device

Maxillary distraction osteogenesis delivers excellent results, particularly in patients with clefts. In the past, devices such as the conventional facemask and the rigid external distraction device have been used to correct maxillary hypoplasia after a Le Fort 1 osteotomy. We describe a new device, the Glasgow extra-oral distraction device. The extent of skeletal and dental stability of corrections achieved in 10 patients with maxillary hypoplasia associated with clefts was satisfactory. This device costs little, can be produced in developing countries, and provides effective treatment for severe secondary deformity associated with clefts.
