Introduction: Purpose of this study is to assess the outcome of autologous blood injection to the
temporomandibular joint in treating chronic recurrent dislocation.
Material and Methods: 15 patients with chronic recurrent temporomandibular joint dislocation
considered in the study underwent single needle arthrocentesis followed by autologous blood
injection in upper joint cavity. The pre-operative findings of patient’s maximum mouth opening
and an evaluation of temporomandibular joint radiograph compared post operatively.
Results: All the patients tolerated the arthrocentesis and intra articular autologous blood injection
without any serious complications.The mean age group was 32.37 years. The mean difference
between the pre and post-operative mouth opening was 2.46 ± 1.96 mm and was assessed by paired t
test. Among the 8 patients who had 2 episodes of dislocation pre operatively only 2 patients continue
to have repeated dislocation (25%) at the end of 3 months post-operatively. Remaining 7 patients
out of 15, who had more than 3 episodes of dislocation pre operatively, experienced no dislocation
during the follow up (100%).
Conclusion: Intra-articular autologous blood injection following single needle arthrocentesis is
simple, minimally invasive and cost effective procedure. The treatment was successful in 86.3% of
cases without any serious complications both during the procedure and during follow up period.
