Maxillofacial Surgeon Dr. S.M. Balaji performed the clinical and radiological investigations. OPG and 3D CT scan showed complete absence of left side angle and ramus of mandible with remnants of bone graft. Dr. Balaji successfully reconstructed the huge mandibular defect maintaining the contour using titanium “L” plate and costochondral rib graft and thus missing condylar component was also reconstructed, the surgical site was closed. Patient feels very happy to have entire surgery done inside the mouth and to have complete facial asymmetry correction without any scars on the face.
