Comparison of different arthrocentesis techniques for the management of symptoms in patients with degenerative joint disorders: A randomized clinical trial.

OBJECTIVES: All arthrocentesis techniques relied on fixed points measured from the cantho-tragal line. However, joint anatomy differs substantially in the different temporomandibular joint disorders (TMD). This study introduces a novel technique, uses patient-specific points without reference to cantho-tragal line, and compares it with two conventional techniques.

METHODS: A total of 144 TMJs were divided into group A (disc displacement without reduction with limitation) and group B (degenerative joint disease). Each group was subdivided into 3 groups according to the technique applied. Nitzan et al. technique (10/2, 20/10 points) in group 1; Alkan and Etöz technique (10/2, 7/2 points) in group 2; and the novel technique (two points in glenoid fossa summit) in group 3.

RESULTS: Group 3 showed better results than groups 1 and 2 in success rate, relocations number, procedure duration, and early pain and maximum mouth opening.

CONCLUSION: The novel technique may be more promising in TMD.
