OBJECTIVE: To assess the efficacy of template as a guide in performing extra-oral vertical ramus osteotomy. METHODS: A 21-year-old male patient, reported with complaints of facial asymmetry and restricted mouth opening due to ankylosis involving the right TMJ. Interpositional arthroplasty along with extra oral vertical ramus osteotomy and coronoidectomy was planned to correct the ankylosis of TMJ and facial asymmetry. An acrylic template was used as a guide for performing the osteotomy. Intra operative accuracy of the osteotomy and post-operative neurosensory functioning of inferior alveolar nerve was assessed subjectively and objectively by static two-point discrimination test. RESULTS: In a follow up period of six months, no subjective and objective sings of neuro sensory impairment were reported. CONCLUSION: Using a template as guide in making vertical ramus osteotomy, avoids intra operative damage to the inferior alveolar nerve. IJBT
