The aim of this study was to evaluate the effectiveness of two-time arthrocentesis and nonsteroidal anti-inflammatory drugs (NSAIDs) as a primary treatment for temporomandibular osteoarthrosis.
Twenty-five patients with moderate or severe TMJ dysfunction were selected from a consecutive series of new patients who were examined at the TMD clinic of Aichi-Gakuin University Hospital during a 1 -year period. All patients had unilateral TMJ symptoms and were given a diagnosis of TMJ osteoarthrosis on MR imaging.
Arthrocentesis was performed two times at an interval of 2 weeks. The NSAID, an oral cox- 2 inhibitor, was given daily for up to 12 weeks until the patients's ymptoms improved. The patients were postoperatively followed up at 2 -week intervals for 12 weeks. Therapy was continued for 12 weeks unless TMJ symptoms improved within this period. The patients who had no or slight TMJ dysfunction at 12 weeks were classified as improved. Those who had moderate or severe TMJ dysfunction were classified as not improved.
The improvement rates were 24%, 28%, 36%, 40%, 44%, and 56% after 2, 4, 6, 8, 10, and 12 weeks, respectively.
The combination therapy was evaluated to be effective. However, the improvement in maximal mouth opening was not satisfactory. Thus, additional treatment should be given to increase maximal mouth opening.
