Evaluation of efficacy of arthrocentesis (with normal saline) with or without sodium hyaluronate in treatment of internal derangement of TMJ – A prospective randomized study in 20 patients

PurposeTo compare the outcome of arthrocentesis alone and arthrocentesis with sodium hyaluronate in internal derangement of TMJ.Materials and methods20 patients of disc displacement with reduction of TMJ were randomized into 2 experimental groups. Control group of patients received arthrocentesis alone and study group of patients received arthrocentesis with sodium hyaluronate. Patients TMJ status and clinical symptoms were evaluated for 6 months follow up. The clinical parameter recorded were maximal mouth opening (MMO), lateral excursions (right and left side), protrusive movement, joint noises, and pain (at rest, at function).ResultsWhen 2 groups are compared there was no statistically significant difference in terms of inter-incisal opening, lateral excursion, protrusive movement, joint noises and pain however the group with sodium hyaluronidase has shown better results than the control group.ConclusionBoth study and control group found to be statistically insignificant but patient who were in the group of arthrocentesis with admission of sodium hyaluronidase had better results.
