Distraction osteogenesis has become an alternative treatment to treat severe craniofacial skeletal dysplasias. A rigid external distraction device has been successfully used to advance the maxilla as well as the maxillary, orbital, and forehead complex (monobloc) in children as young as 2 years, adolescents, and adults. This approach has provided reduced morbidity, and predictable and stable.
Graduated stability plates (gsp) offer the progressive level of fixation required as the advancement increases.
