Management of Exorbitism Using Midface Distraction Osteogenesis

Three-dimensional surgical planning for maxillary and midface distraction osteogenesis.

Computerized surgical planning protocols for distraction osteogenesis are still in their rudimentary phase. The authors have developed a system to plan distraction osteogenesis in craniofacial and maxillofacial surgery that uses three-dimensional computed tomography scans and computer simulation in a virtual reality environment. This involves the creation of a three-dimensional bone model of th...

Midface distraction osteogenesis in cleft patients: a case report.

We present a case of midface distraction in a bilateral cleft lip and palate patient. The patient was a 10-year-old who underwent a high LeFort I osteotomy followed by placement of the Rigid External Distraction halo. Distraction was commenced on the fifth postoperative day at a rate of 1 to 1.5 mm per day until a total of 17 mm of maxillary advancement had been achieved. There were no complica...

A subcranial Le Fort III advancement with distraction osteogenesis as a clinical strategy to approach pycnodysostosis with midface retrusion and exorbitism.

Pycnodysostosis is a rare autosomal recessive skeletal disorder involving a constellation of craniofacial manifestations including midface retrusion. We report the case of a 13-year-old girl with pycnodysostosis who presented with exorbitism, midface retrusion, malocclusion, and obstructive sleep apnea. Here, we describe the successful use of subcranial Le Fort III advancement using distraction...

Distraction Osteogenesis

Distraction osteogenesis is increasingly used for bone lengthening of facial skeleton. Distractors may be intraoral and extraoral. The authors present development of distractors and their use for treatment of facial bones. Procedure may be used for treatment of malformations, syndroms, posttraumatic bone defects and deformities. The advantage of a distractor are a simple and fast procedure, sho...
