Temporo mandibular deformities such as TM Jt ankylosis, recurrant tm jt dislocations are treated with gap arthroplasty and reconstruction of new joint using costochondral graft and superficial temporal fascia. Mandibular jaw deformities like mandibular prognathism or retrognathia can be corrected with necessary osteotomies. Maxillary osteotomies for maxillary retrusion , vertical excess can be planned and done using AO Techniques to achieve normal facial profile.
