The 3D CT scan revealed complete absence of the posterior portion of the lower jaw left side. The left side jaw joint or temporomandibular joint was also absent. Maxillofacial Surgeon Dr. S.M. Balaji successfully performed the jaw reconstruction surgery. A costochondral rib graft was harvested and used to reconstruct the missing left mandibular ramus, condyle and temporomandibular joint. Immediately following jaw reconstruction, the face appeared symmetrical improving her appearance. The girl will require post-surgery physiotherapy to rehabilitate the jaw joint function.
