title: Arthrocentesis followed by intra-articular autologous blood injection for the treatment of recurrent temporomandibular joint dislocation.
abstract: Temporomandibular joint (TMJ) dislocation is an excessive forward movement of the condyle beyond the articular eminence with complete separation of the articular surfaces and fixation in that position. This study was conducted to assess autologous blood injection to the TMJ for the treatment of chronic recurrent TMJ dislocation. Fifteen patients with bilateral chronic recurrent condylar dislocation were included in the study. Bilateral TMJ arthrocentesis was performed on each patient, followed by the injection of 2ml of autologous blood into the superior joint compartment and 1ml onto the outer surface of the joint capsule. Preoperative and postoperative assessment included a thorough history and physical examination to determine the maximal mouth opening, presence of pain and sounds, frequency of luxation, recurrence rate, and presence of facial nerve paralysis. Eighty percent of the subjects (12 patients) had a successful outcome with no further episodes of dislocation and required no further treatment at their 1-year follow-up, whereas three patients had recurrent dislocation as early as 2 weeks after treatment. Autologous blood injection is a safe, simple, and cost-effective treatment for chronic recurrent TMJ dislocation.
