N2 - We retrospectively examined the effect of pumping with injection of sodium hyaluronate into the temporomandibular joint (TMJ) and the other factors influencing outcome in patients with non-reducing disk displacement of the TMJ. Fifty-nine patients underwent pumping with injection of sodium hyaluronate into the TMJ. As control, 62 patients were observed without any treatment. Both groups were observed for 12 months. The relation between outcome and the following clinical characteristics was also studied: sex, age, range of motion for maximal mouth opening, TMJ pain, TMJ noise, tenderness of masticatory muscles, locking duration, intercuspal occlusions, angle of posterior slope of articular eminence and degenerative bony changes of the condyle. Logistic regression analysis revealed that pumping with injection of sodium hyaluronate was related to a good outcome. Clinical characteristics of presentation significantly related to a good outcome were a large maximal mouth opening, a short locking duration, and a steep posterior slope of articular eminence. We conclude that pumping with injection of sodium hyaluronate into the TMJ is an effective treatment method for non-reducing disk displacement of the TMJ and that some clinical characteristics also influence outcome.
