Short-term results of autologous blood injection for treatment of habitual TMJ luxation.

Many surgical and nonsurgical methods for the treatment of temporomandibular joint (TMJ) hypermobility have been published. The purpose of this study was to evaluate the results after autologous blood injection in and around the TMJ for the treatment of habitual luxation. Twenty-five patients were diagnosed as having habitual TMJ luxation and treated with autologous blood injection into the upper joint space and around the joint capsule (group A). A control group of 15 patients with the same diagnosis were subjected to physiotherapy with muscular exercise (group B). Patients in group A were reevaluated 3 months after treatment and those in group B were reevaluated after 3 months of physiotherapy. A statistically significant reduction in maximal mouth opening and TMJ sounds was noted only in group A, whereas the reduction for group B was minimal. These measurements show that intraauricular and periauricular autologous blood injection results in remission of signs and symptoms of TMJ luxation in the short term.
