DISTRACTION OSTEOGENESIS

Distraction osteogenesis, also called callus distraction, callotasis, and osteodistraction, is a surgical process used to reconstruct skeletal deformities and lengthen the long bones of the body. A corticotomy is used to fracture the bone into two segments, and the two bone ends of the bone are gradually moved apart during the distraction phase, allowing new bone to form in the gap.[2][4][5] When the desired or possible length is reached, a consolidation phase follows in which the bone is allowed to keep healing. Distraction osteogenesis has the benefit of simultaneously increasing bone length and the volume of surrounding soft tissues.

The surgical and technological advances made in the field of distraction osteogenesis have provided the oral and maxillofacial surgeons with a safe and predictable method to treat selected deformities of the oral and facial skeleton. In many cases osteodistraction can be used to “grow” bone in the jaws to facilitate implant surgery.

Drs. Friedman and Schulhof uses distraction osteogenesis to treat selected deformities and defects of the oral and facial skeleton. If you have questions about distraction osteogenesis, please call our office and schedule an appointment with Drs. Friedman and Schulhof.

Frequently Asked Questions About Distraction Osteogenesis

What does the term distraction osteogenesis mean? Simply stated, distraction osteogenesis means the slow movement apart (distraction) of two bony segments in a manner such that new bone is allowed to fill in the gap created by the separating bony segments.

Is the surgery for distraction osteogenesis more involved than “traditional surgery” for a similar procedure? No. Distraction osteogenesis surgery is usually done on an outpatient basis with most of the patients going home the same day of surgery. The surgical procedure itself is less invasive so there is usually less pain and swelling.

Will my insurance company cover the cost of osteogenesis surgical procedure? Most insurance companies will cover the cost of the osteogenesis surgical procedure provided that there is adequate and accurate documentation of the patient’s condition. Of course, individual benefits within the insurance company policy vary. After you are seen for your consultation at our office, we will assist you in determining whether or not your insurance company will cover a particular surgical procedure.

Is distraction osteogenesis painful? Since all distraction osteogenesis surgical procedures are done while the patient is under general anesthesia, pain during the surgical procedure is not an issue. Postoperatively, you will be supplied with appropriate analgesics (pain killers) to keep you comfortable, and antibiotics to fight off infection. Activation of the distraction device to slowly separate the bones may cause some patients mild discomfort. In general, the slow movement of bony segments produces discomfort roughly analogous to having braces tightened.

What are the benefits of distraction osteogenesis vs. traditional surgery for a similar condition? Distraction osteogenesis surgical procedures typically produce less pain and swelling than the traditional surgical procedure for a similar condition. Distraction osteogenesis eliminates the need for bone grafts, and therefore, another surgical site. Lastly, distraction osteogenesis is associated with greater stability when used in major cases where significant movement of bony segments are involved.

What are the disadvantages of distraction osteogenesis? Distraction osteogenesis requires the patient to return to the surgeon’s office frequently during the initial two weeks after surgery. This is necessary because in this time frame the surgeon will need to closely monitor the patient for any infection and teach the patient how to activate the appliance.

In some cases, a second minor office surgical procedure is necessary to remove the distraction appliance.

Can distraction osteogenesis be used instead of bone grafts to add bone to my jaws? Yes. Recent advances in technology have provided the oral and maxillofacial surgeon with an easy to place and use distraction device that can be used to slowly grow bone in selected areas of bone loss that has occurred in the upper and lower jaws. The newly formed bone can then serve as an excellent foundation for dental implants.

Does distraction osteogenesis leave scars on the face? No. The entire surgery is performed within the mouth and the distraction devices used by Drs. Friedman and Schulhof remain inside the mouth. There are no facial surgical incisions are made so no facial scars result.

Are there any age limitations for patients who can receive osteogenesis? No. distraction osteogenesis works well on patients of all ages. In general, the younger the patient the shorter the distraction time and the faster the consolidation phase. Adults require slightly longer period of distraction and consolidation because the bone regenerative capabilities are slightly slower than those of adolescence or infants.
