One of the more involved reconstructive procedures that Boston Children’s conducts is distraction osteogenesis (DO) for facial skeleton deformities. During this procedure, a bone is separated into two segments (osteotomy) and lengthened gradually under tension using a distraction device. The movement of the two pieces of bone results in a gap, where new bone forms.
According to Bonnie Padwa, MD, DMD, chief of the Oral and Maxillofacial Surgery Program, DO has revolutionized the field. “Before, surgeons had to lengthen bones by taking bone grafts from the patient's hip, rib, or cranium,” she says. “This required a long operation and in infants, there's a relatively small amount of bone that's available to harvest for grafts. Distraction avoids many of these problems and significantly reduces healing time.”
