Characteristics of patients with temporomandibular joint osteoarthrosis on magnetic resonance imaging

Abstract

Introduction: Temporomandibular joint (TMJ) dysfunction is a common condition that is best evaluated with magnetic resonance (MR) imaging. The aim of this study was to investigate the characteristics of the patients with TMJ osteoarthrosis on MR imaging. Methods: The MR images of 206 TMJs of 103 patients with temporomandibular disorders (TMD) were evaluated retrospectively in this study. The relationship between osteoarthrosis and age, gender, TMJ pain and MR imaging findings, such as disc displacement with or without reduction and TMJ effusion, was analysed. Results: The patients with TMJ osteoarthrosis (mean: 51.6 years) were significantly older than those without osteoarthrosis (mean: 44.8 years, P = 0.027). The incidence of the patients with TMJ osteoarthrosis was significantly different between with (10.0 %) and without reduction (57.0 %, P < 0.001). Logistic multivariate regression analysis demonstrated that disc displacement without reduction was significant in patients with TMJ osteoarthrosis (odds ratio = 12.285, P < 0.001). Conclusions: This study suggests that characteristics of the patients with TMJ osteoarthrosis on MR imaging include older and disc displacement without reduction.

Diagnostic significance of magnetic resonance imaging in distinguishing temporomandibular disorders: a retrospective chart review

“…The diagnosis of osteoarthritis should be based on the evaluation of MRI images in combination with clinical examination. It is generally believed that the most common pathological manifestation of the condylar process is articular surface degeneration [ 12 ]. Osteoarthritis and internal disorders coexist in only one-third of cases, which means that the view that subclinical osteoarthritis leads to the pathological tissue response to internal disorders should be reexamined [ 13 ].…”

Examination for the Factors Involving to Joint Effusion in Patients with Temporomandibular Disorders Using Magnetic Resonance Imaging

“…MRI (1.5 Tesla MR unit; EXCELART VantageMRT-2003; Canon Medical Systems, Otawara, Japan) with a surface coil for the TMJ included proton density-weighted sagittal and coronal imaging in the closed mouth position and the maximum mouth-opening position (repetition time/echo time 2000 ms/18 ms, field of view 130 mm × 130 mm, matrix size 256 × 224, and 1 acquisition). T2-weighted sagittal and coronal imaging in the closed mouth position and the maximum mouth-opening position (repetition time/echo time 3500 ms/100 ms, field of view 130 mm × 130 mm, matrix size 256 × 192, and 2 acquisitions) was also included [27,28]. Joint effusion, disc displacement, disc deformation, and bone deformation were analyzed by MR imaging.…”

Artificial intelligence for detecting temporomandibular joint osteoarthritis using radiographic image data: A systematic review and meta-analysis of diagnostic test accuracy

“…However, the first two methods sometimes provide limited information about the joint status of patients with TMJOA. Therefore, medical imaging, such as magnetic resonance imaging (MRI), cone-beam computed tomography (CBCT), and orthopantomogram (OPG), is often necessary to assess osteoarthritis [6][7][8]. The X-ray passed through the temporomandibular joint area and was subsequently detected by a detector.…”
