“…Several studies have reported cases of patients with joint calcifications, the average age of whom was over 45 years. 19,21,28,29 In the present study, the joint was affected bilaterally in the majority of cases (75.0%); this contrasts with data presented in the literature.…”

“…Although MRI is considered the imaging modality of choice for the diagnosis of TMJ pathology, 28,29 CBCT, which has been widely used in dentistry for various purposes, is the most suitable imaging method for evaluating joint structures and the potential presence of mineralized free bodies. 6 However, even when such bodies are not visible on a CBCT examination, we cannot exclude the possibility of pathology caused by calcifications, as the bodies may not have been sufficiently calcified when the image was acquired.…”

Purpose: The purpose of this study was to use cone-beam computed tomography (CBCT) images to determine the prevalence of calcifications in the temporomandibular joint (TMJ) and to evaluate any associations between the presence of such calcifications and degenerative bone alterations of the TMJ, sex, or age. Materials and Methods: In this retrospective study, 1,058 CBCT exams were analyzed, and data regarding the presence and quantity of calcifications, the affected side, any degenerative alterations of the condyle, sex, and age were collected. To evaluate associations between the presence of calcifications and sex or age, the Fisher exact test or the Spearman correlation coefficient, respectively, was used. To assess the association between the presence of calcifications and joint bone alterations, the chi-square and Fisher exact tests were used. The significance level adopted was 5% (P<0.05). Results: Twenty-eight patients (2.7%) presented with TMJ calcifications, including 23 women (82.1%) and 5 men (17.9%). Significant correlations were found between the presence of calcifications and age (P<0.05) and between the presence of calcifications and the presence of condylar alterations (P<0.05), with 73.2% of patients with bone alterations having TMJ calcifications. Conclusion: It may be concluded that, although rare (with a prevalence of only 2.7%), intra-articular calcifications are associated with both degenerative bone alterations and age.

“…MRI, confirming the typical nodules reported as pathognomonic characteristics [22,26]. SC images include chondral and calcified loose bodies in the TMJ spaces, but it is possible to also observe them in other joint pathologies, such as chondrosarcoma or benign inflammatory illnesses such as osteoarthritis, rheumatoid arthritis and avascular necrosis [25,27].…”

“…CT showed low attenuation of non-mineralized nodules of SC due to the associated joint fluid and the high-water content of the hyaline cartilage neoplastic tissues. CT is particularly helpful for finding characteristics of calcified nodule multiplicity [25]. In our case, the use of contrast media agents (CMA) in the CT scan was not justified because SC does not develop new blood vessels around the lesion, and the first image series clearly showed typical nodules located in the expanded joint space without involving other tissues.…”

“…Arthroscopic procedure in the TMJ has been considered as effective in the diagnosis and removal of loose bodies of synovial chondromatosis, and it appears to offer benefits in controlling pain and functional improvements, with low range of mouth opening limitations and complications. The achievement of arthroscopy is also very operatordependent, and iatrogenic damage to the articular cartilage might occur, which can considerably modify the outcome; however, recurrences can be treated effectively with additional surgical intervention [20][21][22][23][24][25][26][27][28][29][30].…”

Uncommon tumors of temporomandibular joint: An institutional experience and review

et al. 2020

View full text Add to dashboard Cite

BackgroundThe temporomandibular joint (TMJ) harbors a myriad of pathologic alterations including arthritides and benign and malignant neoplasms.MethodsHerein, we describe our institutional experience of some uncommon and unusual synovial pathologies of the TMJ along with a review of literature. We searched through the archives of department of pathology and institutional electronic medical record for specimens of TMJ between 1999 and 2019. Hematoxylin and eosin slides were reviewed and data (final diagnosis, age, gender, clinical presentation, tumor size, treatment modality, recurrence, and vital status) were collected.ResultsA total of seven cases were identified including four cases of synovial chrondromatosis; and one case each of tenosynovial giant cell tumor, localized type, tenosynovial giant cell tumor, diffuse type, and synovial sarcoma.ConclusionsThe article emphasizes on the clinical, radiologic, pathologic, and molecular features of these uncommon entities. The differential diagnosis of each entity is also discussed. Current updates in the management are also reviewed.
