Viscosupplementation-the concept in alleviating symptoms of temporomandibular joint osteoarthritis: A clinical study
Purpose: The aim of the present study was to evaluate the efficacy of hyaluronidase injection in the treatment of temporomandibular joint osteoarthritis.
Patients and Methods: Patients with symptoms of unilateral temporomandibular joint osteoarthritis, non-responsive to conservative measures such as pharmacotherapy, splint therapy and arthrocentesis were treated with injections of 150 TRU of hyaluronidase. The outcome variables were maximum voluntary mouth opening, deviation on mouth opening, pain- visual analog scale, joint sounds (crepitations/clicking).
Results: 54 patients, including 28 females and 26 males were studied. The age group was 25 to 40 years. Patients received 3 injections of hyaluronic acid at 10 days interval according to their symptoms. 38 patients showed a significant reduction in symptoms after the first injection. With the third injection all patients obtained complete relief and were symptom free during the follow up period.
Conclusion: Intra articular injection of Hyaluronic acid is a highly effective treatment modality in patients with TMJ OA, non-responsive to other conservative measures.
