Traumatic cranial injury sustained from a fall on the rigid external distraction device.
Distraction osteogenesis has become a popular treatment of congenital maxillocraniofacial anomalies. Many ingenious internal and external devices have been developed and used. The rigid external distraction system based on systems previously used in correction of maxillary retrusion offers postoperative adjustment in two dimensions. Figueroa and Polley reported the use of this device with minimal morbidity in children as young as 5 years of age. They reported no problems with infection, bleeding, pain, loosening of the intraoral splint, dental injury, or wear problems in a series of 14 consecutive cleft patients. Recent modification of the system, rigid external distraction II, has allowed it to be applied to more complex craniofacial deformities that require a LeFort III osteotomy. A review of the neurosurgery and orthopedic literature revealed that halo complications relate primarily to the skull pins. In most cases, these complications can be prevented if the device is carefully applied and monitored. Early recognition and prompt treatment of complications are important. After experience with this system for advancement at the LeFort III level, six patients with various syndromes involving the craniofacial skeleton have undergone LeFort III level distraction osteogenesis with the rigid external distraction device in combination with a planned and stabilized frontosupraorbital advancement. In one of these cases, a 7-year-old child fell on the device after discharge from the hospital and sustained a compound depressed skull fracture that required debridement and repair.
