[Frontofacial monobloc advancement using the Rigid External Distraction (RED-II) system].

: One-stage frontofacial monobloc advancement has been used to treat patients with craniofacial synostosis including Crouzon disease. Nishimoto et al. first applied a rigid external distraction system for two patients. However, precise surgical techniques and proper indication for this gradual distraction method have not yet been established. This report describes the advantages and detailed surgical methods of frontofacial monobloc advancement using a Rigid External Distraction (RED- II) System. Three patients with severe craniofacial synostosis including Crouzon disease and Treacher Collins syndrome were treated. The ages of patients were 9, 9, and 8 year old, respectively. The RED- II System was safely applied for these young children and cosmetic results were sufficient. No major postoperative complications occurred.
