Treatment of chronic recurrent dislocation of temporomandibular joint by autologus blood injection

The aim of this study was to evaluate the efficacy of autologus blood injection in the management of recurrent temporomandibular joint (TMJ) dislocation. Methods: A total of 11 patients, 4 males, 7 females, mean age of 58.6 years and suffering from recurrent dislocation of TMJ, were included in the study. In all the patients the procedure included anesthesia-local or sedation, arthrocentesis which was followed by autologous blood injection in the upper joint cavity. The peri-articular tissues were also infiltrated with autologous blood. Post procedure advice included restricted mouth activity and liquid diet for a month. Results: The results indicate that success rate of treatment of recurrent dislocation of TMJ is 72.8% which can be considered as impressive. The recurrence was noticed in 27.2% cases after one year follow up. Conclusion: Autologus blood injection is an effective, simple, non-invasive, and safe procedure for treatment of recurrent dislocation of TMJ and can be performed on outpatient basis.
