Treatment of Temporomandibular Joint Arthritis with Triamcinolone Acetonide and Hyaluronic Acid Injection: An Observational Study.

Temporomandibular joint (TMJ) arthritis is a common cause of orofacial pain with distressing symptoms. The patients most commonly females are often anxious and worried due to the typical gritty sound produced during chewing moments. In other cases there is pain followed by decreased mouth opening. Currently the treatment is not standardised though the clinicians are treating these disorders either by oral medications; splintage or by injections. Though local injection of Triamcinolone acetonide and Hyaluronic acid is an innovative therapy yet it is elusive of much research. The main aim of the present study is to evaluate the efficacy of with Triamcinolone acetonide and Hyaluronic acid in treating temporomandibular joint arthritis. The present study is a prospective non randomized clinical trial of 100 patients in a tertiary referral centre. The patients diagnosed with temporomandibular joint arthritis were treated with local infiltration of 40 mg triamcinolone acetonide along with 20 mg of hyaluronic acid; one injection every week for 4 weeks. The pre-treatment and post-treatment data was compared using student paired t test and Mann-Whitney U test. Majority of the patients showed relief in symptoms like pain (87/96) and clicking sounds (81/88) and the difference was statistically significant ( < 0.05). Though other symptoms like restrictive mouth opening; discomfort on lateral and medial movement were also relieved in 9/15 patients and 21/23 patients respectively however the difference was not statistically significant. We highly recommend the use of Triamcinolone acetonide and hyaluronic acid injection in TMJ arthritis as it helps in relieving pain and clicking of sound in majority of the patients. The treatment is an out-patient department procedure with almost no side effects in most of the patients. The cost effectiveness of the treatment is another benefit.
