“…On the other hand, temporomandibular joint internal derangement (TMJ ID) is widely reported to be associated with mandibular asymmetry. Schellhas et al (1990) suggested that disc displacement, internal derangement (ID), or degenerative joint disease could be a main cause of mild and moderate mandibular asymmetries. Various studies have investigated occlusal problems as a predisposing factor for TMJ ID.…”

The purpose of this study was to examine the changes in the temporomandibular joint (TMJ) and ramus after sagittal split ramus osteotomy (SSRO) with and without Le Fort I osteotomy.The subjects consisted of 87 Japanese patients diagnosed with mandibular prognathism with and without asymmetry. They were divided into 2 groups (42 symmetric patients and 45 asymmetric patients). The TMJ disc tissue was assessed by magnetic resonance imaging (MRI) and the TMJ space, condylar and ramus angle were assessed by computed tomography (CT) preoperatively and postoperatively.Medial joint space on the deviation side in the asymmetry group was significantly larger than that in the symmetry group (P=0.0043), and coronal ramus angle on the non-deviation side in the asymmetry group was significantly larger than that in the symmetry group preoperatively (P=0.0240). The horizontal condylar angle on the deviation side in the asymmetry group was significantly larger than that in the symmetry group (P=0.0302), posterior joint space on the non-deviation side in the symmetry group was significantly larger than that in the asymmetry group postoperatively (P=0.00391).The postoperative anterior joint space was significantly larger than the preoperative value on both sides in both groups (the deviation side in the symmetry group: P=0.0016, the non-deviation side in the symmetry group: P<0.0001, the deviation side in the asymmetry group: P=0.0040, the non-deviation side in the asymmetry group: P=0.0024). The preoperative disc position could was not changed in either group. These results suggest that significant expansion of anterior joint space could occur on the deviation side and non-deviation side in the asymmetry group as well as on both sides in the symmetry group, although disc position did not change in either group.

“…60,62,63 Although radiographic studies are sparse, different imaging modalities have been applied to assess JOA: plain films, 59 conventional tomography 60 and MRI. 62,63 However, CT studies have rarely been carried out, 64 and only a few CBCT studies on JOA are available. After an early case report, 65 two larger studies have been published.…”

The present review will give an update on temporomandibular joint (TMJ) imaging using CBCT. It will focus on diagnostic accuracy and the value of CBCT compared with other imaging modalities for the evaluation of TMJs in different categories of patients; osteoarthritis (OA), juvenile OA, rheumatoid arthritis and related joint diseases, juvenile idiopathic arthritis and other intra-articular conditions. Finally, sections on other aspects of CBCT research related to the TMJ, clinical decision-making and concluding remarks are added. CBCT has emerged as a cost-and dose-effective imaging modality for the diagnostic assessment of a variety of TMJ conditions. The imaging modality has been found to be superior to conventional radiographical examinations as well as MRI in assessment of the TMJ. However, it should be emphasized that the diagnostic information obtained is limited to the morphology of the osseous joint components, cortical bone integrity and subcortical bone destruction/production. For evaluation of soft-tissue abnormalities, MRI is mandatory. There is an obvious need for research on the impact of CBCT examinations on patient outcome.

“…Occlusal discrepancies like malocclusion are not uncommon [12]. Occlusal changes include reduced overbite and anterior open bite [10,13]. Internal derangements occur in about one-third of the patients [14].…”
