Comparison of Intraoral vertical ramus osteotomy and High condylectomy with disc repositioning in the management of non-reducing disc displacement of TMJ – A randomised control trial

30 subjectsfulfilling the inclusion and exclusion criteria will be randomly allocated into02 groups after informed consent. Pre-operative MRI and clinical parameterswill be recorded for all patients. The patients will be randomly allocated to02 groups. Group A will be managed by Intraoral Vertical ramus osteotomyfollowed by Maxillomandibular fixation for 02 weeks and Group B will be managedby high condylectomy with disc repositioning by partial/full thickness excisionwith/without lateral tuberclectomy according to existing contemporary surgicalprotocols. The clinical parameters will be recorded at 03, 06 and 12 months post-operatively. Post-operative MRI will betaken at 12 months post-surgery and assessed. The results will be analysedusing appropriate statistical tests to establish the efficacy of both theprocedures and to establish a comparison between the two procedures
