“…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.

“…Therefore, multiple LBs that slowly grow over time are typical findings of SC. 2,12 There are few reports of single LBs in TMJ related to SC and, in contrast to the present case, they were large masses (6×4 mm and 16×9 mm). 6,13 The 2year follow-up PR also showed no apparent progression of the condition or enlargement of the LB.…”

Loose intra-articular bodies are a rare finding in the temporomandibular joint. Surgical removal of the loose bodies isoften described as the only treatment option; however, it presents possible postoperative complications. The aim of thispaper is to report the successful conservative management of a temporomandibular disorder associated with a singleloose intra-articular body. A 62-year-old woman presented with pain in the right temporomandibular joint andpre-auricular region, limited mouth opening and open-lock episodes. Panoramic radiography and cone-beam computedtomography exams revealed the presence of a single loose body located anterior to the right condyle. Magnetic resonanceimages showed bilateral anterior disc displacement without reduction. A non-invasive approach consisting of an occlusalsplint and low-level laser therapy associated with home-based physical therapy was performed for management ofclinical signs and symptoms. The patient was followed up for 2 years and presented significant pain reduction andimprovement in the range of mandibular movements. The combination of conservative therapies may be an alternativefor surgical intervention to control pain and improve mandibular function in patients with temporomandibulardysfunction associated with a loose body in the temporomandibular joint.

“…Since these clinical signs are non-specific, and similar to those of internal disorders or arthritis, delayed diagnosis is frequent. In the case reports described by Benslama et al, the average delay in diagnosis was 11 months, and it could even reach 31 months according to Ardekian et al [ 15 , 16 ]. Considering these more frequent diseases do not require any particular TMJ imaging, their diagnosis being based on the clinical examination, practitioners do not systematically prescribe complementary X-Rays or MRI examinations [ 17 ].…”

Diagnosis of Synovial Chondromatosis of Temporomandibular Joint: Case Report and Literature Review

et al. 2021

Synovial chondromatosis is a non-cancerous tumor characterized by the formation of multiple nodules of cartilage due to metaplastic development of the synovial membrane. Etiology can be a primary lesion, of which pathogenesis remains unknown, or low-grade trauma or internal disorders. This pathology can long remain undiagnosed and leads to therapeutic wandering, especially since clinical manifestations are non-specific. Symptoms may mimic temporomandibular disorders and dental orthopantomogram does not always show intra-articular calcified bodies. Cone beam computed tomography (CBCT) and magnetic resonance imaging (MRI) are tests of choice for the diagnosis of this pathology. This case report describes the clinical manifestations, diagnosis and management of a case of synovial chondromatosis involving the temporomandibular joint, in a 21-year-old woman who was initially treated for two years for a common temporo-mandibular disorder. The evidence gathered during the medical interview and clinical examination led us to suspect synovial chondromatosis of the temporomandibular joint. Prescription of a CBCT and MRI confirmed the diagnosis of her temporomandibular joint disorder and led to a successful arthroplasty.
