“…The results of this study showed that disk mobility increased more frequently after arthroscopic surgery than after nonsurgical treatments. This result was consistent with the result of Ohnuki et al 4 . They also reported that improvement of disk mobility was observed after arthroscopic surgery, especially in the joints with successful outcome.…”

Abstract:Purpose: To assess the influence of arthroscopic surgery on radiographically evident degenerative change of the temporomandibular joint (TMJ). The posttreatment course was compared between the joints that underwent arthroscopic lysis and lavage and those that underwent nonsurgical treatment.Patients and Methods: Twenty-eight patients agreed to imaging follow-up examination of 35 joints and were included in this study. Twenty-four joints of 19 patients underwent only nonsurgical treatment (nonsurgical joints). While, eleven joints of nine patients had failed the nonsurgical treatment and consequently underwent arthroscopic lysis and lavage (arthroscopic joints). The joints were assessed at first visit and at least 20 months later (mean 79 months) for disk displacement, disk position, disk morphology, disk mobility, condylar morphology, morphology of the articular eminence, and horizontal condylar angle and size. Thereafter, interval change was assessed and compared between the groups. Results:There was no significant difference in the prevalence of the progressive degenerative changes between the groups. In addition, there was no significant difference in the change of size and morphology of the condyle. However, a higher prevalence of improvement of disk mobility in the arthroscopic joints rather than the nonsurgical joints was significant (Goodness test of fit for chi-square, p<0.05). Conclusions:The results of this study suggest that the posttreatment course of radiographically evident degenerative change was not significantly different between arthroscopy and nonsurgical treatment; however, arthroscopic surgery showed a greater ability to improve disk mobility. In imaging follow-up, arthroscopic lysis and lavage is a minimally invasive treatment modality that is equivalent to nonsurgical treatment.

“…Cortical bone begins to form around the periphery of the condyle during 12 to 14 years old, and by the age of 21–22, full development of the mandibular condyle is accomplished 30 . Disc morphology was classified into 4 types (biconcave, enlargement of the posterior band, even thickness, and biconvex) or 5 types (biconcave, thick posterior band, lengthened, biconvex, folded, and rounded) in previous reports 16 31 . Based on pertinent literatures, all the data was divided into 3 subgroups by age, 3 by follow-up period, 5 by disc morphology, 4 by Wilkes stage (stage IV and V were merged), and 2 by joint effusion.…”

Treatment procedures for anterior disc displacement (ADD) of temporomandibular joint (TMJ) are far from reaching a consensus. The aim of the study was to evaluate disc status changes of anterior disc displacement with reduction (ADDWR) and without reduction (ADDWoR) comparatively, to get a better understanding of the disease progress without intervention. This longitudinal retrospective study included 217 joints in 165 patients, which were divided into ADDWR group and ADDWoR group based on magnetic resonance imaging (MRI) examination. The joints were assessed quantitatively for disc length and displacement distance at initial and follow-up visits. Disc morphology, which was classified in 5 types, was also evaluated. Paired t-test and Wilcoxon signed rank test were used to assess intra-group differences and independent t-test for inter-group differences. Moreover, analysis of covariance was applied to analyze influential factors for changes in disc length and displacement distance. According to our results, discs tended to become shorter, move further forward and distort more seriously in ADDWoR group than in ADDWR group after follow-up. Moreover, discs were prone to become shorter and more anteriorly displaced in teenagers, type I and III morphologies, advanced Wilkes stages, or those with joint effusion. Follow-up period seemed to be not critical.

“…It is controversial whether or not the changes in arthroscopic findings parallel the prognosis of symptoms. Some studies [6] showed that clinical signs and symptoms of TMD can be alleviated by non-surgical and arthroscopic treatments but most discs still remained anteriorly displaced without reduction despite treatment. It has also been found that the identification of disc displacement alone is not sufficient for surgical intervention as asymptomatic disc displacement of the TMJ has been observed in healthy volunteers as well.…”

Objectives: To study correlations between magnetic resonance imaging, arthroscopic and clinical findings in patients with temporomandibular joint disorders in Manitoba. Study Patients and Methods: A retrospective chart review was conducted on temporomandibular joint disorders patients who were diagnosed with MRI scan and treated with arthroscopic lysis and lavage at Health Sciences Centre and Seven Oaks General Hospital from 2006-2012. A data capture sheet collected clinical findings, disc position inferred from MRI scan and arthroscopic findings from patient records. The data was analyzed using the Minitab 15 Statistical Package. Results: Eighty-seven joints of 58 patients were evaluated with the average age of 36.9 years and mean follow up of 6 months. MRI showed 52% of joints with anterior disc displacement without reduction. Arthroscopic findings showed adhesions (88.5%), hyperemia (47.1%), and synovitis (31.0%) regardless of stages of internal derangement. There was a significant improvement in pain (P<0.05), and in the Interincisal Distance (IID) (from 29.2 mm to 34.4 mm) postoperatively. Conclusion: Although arthroscopic findings did not correlate with disc position as per MRI scan, arthroscopic lysis and lavage has significantly improved pain, and jaw range of motion.
