The goal of the treatment is to elongate the deficient jaw bone to restore facial symmetry and correct the slanting bite (occlusion). To achieve this, an advanced and effective treatment technique is distraction osteogenesis. This is a new technique for regenerating new bone by slow, progressive stretching of the bone, without requiring a bone graft.
Eminent Craniofacial Surgeon Dr. S.M. Balaji is a pioneer in introducing this revolutionary technique and has successfully rehabilitated the maximum number of patients afflicted with facial disfigurements in the country.
In distraction osteogenesis, the jaw bone on the deficient side is cut. A sophisticated device called distractor is placed such that the two arms of the device are fixed to the two segments of jaw bone. After a few days, a screw attached to the distractor is turned gradually, ideally at a rate of 1 mm per day. When this is done, the two cut segments move apart and new bone is formed in the resultant gap. After the required length is achieved and new bone is stabilized, the distractor device is removed subsequently correcting the asymmetry of the face.
This is a powerful tissue engineering technique for generating bone for the desired volume. The overlying soft tissues that are deficient also are expanded, therefore along with the underlying bone deformity, the overlying skin and soft tissue defect is also corrected.
This is the only procedure to increase the size of the jaw bones after the cessation of actual bone growth. For this patient, Dr. Balaji adopted a stage-by-stage rehabilitation. To correct the jaw deformity, he applied the innovative simultaneous maxillary and mandibular distraction procedure wherein new bone is formed in both the upper and lower jaws simultaneously to restore facial symmetry.
