Benefit of Temporomandibular Joint Lavage With Intra-Articular Steroids Versus Lavage Alone in the Management of Temporomandibular Joint Involvement in Juvenile Idiopathic Arthritis

摘要

PurposeThe aim of the present investigation was to evaluate, in patients with juvenile idiopathic arthritis, the effect of lavage with or without intra-articular corticosteroid (IACS) injection on clinical temporomandibular joint (TMJ) signs and symptoms of inflammation and changes in acute inflammation as assessed using magnetic resonance imaging (MRI). Materials and MethodsForty-one patients (mean age, 13.6?±?4.0?yr) with juvenile idiopathic arthritis participating in a large prospective juvenile inflammatory rheumatism cohort study (JIRcohorte) were included in this study. Clinical history, examination, and MRI were carried out at baseline and 6?months after intervention, if any. Twenty-one patients underwent lavage and IACS injection in at least 1 TMJ, 8?patients underwent lavage of at least 1 TMJ, and 12 patients were followed with no intervention. Outcomes measured were maximal mouth opening, Helkimo dysfunction index scores, pain intensity, and acute inflammation as assessed using MRI. ResultsAll groups showed a mean increase in mouth opening and mean decrease in pain intensity. The mean Helkimo clinical dysfunction score decreased for the 2 intervention groups but not for the control group. The mean Helkimo anamnestic dysfunction score decreased for the lavage with IACS group but not for the lavage-only group. The only statistically relevant difference was found for the Helkimo anamnestic dysfunction score comparing the lavage-only with the lavage with IACS group, with a more positive effect found in the lavage with IACS group. More than 50% of joints in each group showed no change at MRI examination. Joints with lavage and ICAS injection showed better improvement than joints that had lavage only or no intervention. ConclusionTMJ lavage with or without IACS injection cannot be claimed to systematically decrease pain, increase mouth opening, or resolve acute inflammation. Despite a tendency for improvement, response to this treatment is very patient dependent and can be determined by an array of other variables.
