Arthrocentesis A Minimally Invasive Method for Tmj Disc Disorders - A Prospective Study

Abstract

Background: Temporomandibular joint (TMJ) disc disorders are one of the major concerns to the mankind and doctors in day to day life due to its complex nature and failure to treat these kinds of conditions successfully. Objectives: The aim of the present study was to evaluate the efficacy of arthrocentesis in patients suffering from TMJ disc disorders. Materials and Methods: A total of 50 subjects suffering from TMJ disc disorders were selected and treated by arthrocentesis. The subjects were followed up for a period of one year. Results: The mean maximal mouth opening prior to arthrocentesis was 32.13mm and after the procedure the mean maximal mouth opening was 46.6mm. The mean right and left lateral movements before arthrocentesis were 7.15mm and 7.59mm respectively, and the mean right and left lateral movements of 9.49 and 9.31 respectively were present after the procedure. The mean degree of pain before arthrocentesis was 8.7, and after the procedure the mean degree of pain was 1.13 as per the visual analogue scale. Conclusion: The findings of this study suggested potential utility of arthrocentesis in the management of TMJ disc disorders.
