Maxillofacial Surgeon Dr. S.M. Balaji performed the clinical and radiological investigations. OPG and 3D CT scan showed complete absence of left side body, angle and ramus of mandible including condylar component. Dr. Balaji successfully reconstructed the huge mandibular defect through the previous scar maintaining the contour of mandible using titanium “L” plate and costochondral rib graft and thus missing condylar component was also reconstructed, the surgical site was closed in layers. Patient feels very happy to have complete facial asymmetry correction in a single surgery. Following good bone formation dental implants will be fixed to enhance his chewing ability.
