Explaining the uniqueness of the procedure, Dr K Sridhar, Director, Institute of Craniofacial, Aesthetic & Plastic Surgery, SIMS Hospital, said, “We have performed total jaw joint replacement for three different patients. In one patient, who had zero mouth opening following a jaw surgery done elsewhere, the damaged jaw bone part was replaced with an artificial part made of titanium metal. The same was done for the second patient who had complete ‘ankylosis’ (immobile joint) of temporomandibular joint (TM joint), which acts like a sliding hinge, connecting jawbone to skull. This patient also had the complaints of sleep apnoea (snoring and sleep disorder due to less oxygenation) and hypoplasia of jaw bone (smaller than normal jaw bone). For this patient, first the jaw bone was lengthened with distraction and later total joint replacement was performed.
