Abstract
Purpose
Arthrocentesis is an effective, simple and minimally invasive treatment in patients with temporomandibular joint (TMJ) closed lock (CL). The aim of this study was to compare the effectiveness of one- or two-session arthrocentesis procedures in the management of TMJ-CL.
Materials and Methods
A retrospective cohort study was conducted using the files of patients with TMJ-CL according to diagnostic criteria for TMD. Patients who underwent one- or two-session arthrocentesis were included to the study. The decision of one or two session arthrocenthesis were given according to patients's choice. Patients who accepted a second arthrocentheis procedure were assigned to group 1 (repeated arthrocentesis group), and patients who did not accept, to group 2 (arthrocentesis group). The primary predictor variable was treatment method. TMJ pain (VAS) and maximal mouth opening (MMO) were selected as the outcome variables. To evaluate the clinical outcomes of one or two-session arthrocentesis, MMO and VAS values before the treatment and at 1, 3, and 6 month follow-up were analysed. Descriptive, comparative, correlation, and multivariate analyses were conducted.
Results
Thirty patients (25 female and 5 male) with TMJ disc displacement without reduction were enrolled in the study. Each group consisted of 15 patients. Statistically significant decrease in pain scores and an increase in maximum mouth opening values were observed in both treatment groups at 3 and 6 months (p<.05). At 6 months, mouth opening values were significantly higher, and the pain levels were significantly lower in patients who received two arthrocentesis.
Conclusion
Repeated arthrocentesis is more successful to reduce pain and improve maxium mouth opening, than a single intervention in the treatment of TMJ-CL.
