Materials and Methods: Medical records of 49 patients (57 TMJs) treated between 2018 and 2022 were retrospectively analyzed. Patients were divided into two groups: those who received arthrocentesis only (AO, n=26) and those who received arthrocentesis combined with a stabilization splint (A+SS, n=23). Pain intensity was evaluated using a visual analogue scale (pVAS), and maximum interincisal opening (MIO) was measured at baseline (T0), 1 month (T1), and 12 months (T2) post-treatment. Intragroup and intergroup comparisons were performed using appropriate statistical tests based on data distribution.
Results: Both groups showed significant improvements in pVAS and MIO over time (p<0.001). At T1, the AO group demonstrated greater pain reduction (p<0.05), while the A+SS group showed greater MIO improvement (p<0.05). However, no significant differences were observed between groups at T2 for either parameter (p>0.05).
Conclusion: Arthrocentesis alone and in combination with a stabilization splint provided similar long-term outcomes in patients with DDwoR. Although the combined therapy yielded early functional benefits, these advantages were not sustained at the 1-year follow-up. Arthrocentesis appears to be a practical and effective standalone treatment option for DDwoR.}, number={1}, organization={YOK}
