A case of synovial chondromatosis of the temporomandibular joint secondary to preauricular trauma

Synovial chondromatosis originally arising in the lower compartment of temporomandibular joint: A case report and literature review

“…Surprisingly, and without knowing the cause, most cases of SC involved the upper compartment of the joint and in the few cases where loose bodies were found inside the lower compartment it was due to a perforation of the articular disc and the subsequent migration of these bodies from the upper compartment. Besides the cases expanding to extra-articular region, there were 13 cases in which the lower compartment was involved of which nine cases were associated with perforation (Von Lindern et al, 2002;Petito et al, 2000;Holmlund et al, 2003;Zha et al, 2009;Sembronio et al, 2008;Koyama et al, 2001;Thompson et al, 1995) and in one case SC was present in both the upper and the lower compartments without perforation (Sato et al, 2009).…”

Three Case Reports of Synovial Chondromatosis of Temporomandibular Joint: Histopathologic Analyses of Minute Cartilaginous Loose Bodies From Joint Lavage Fluid and Comparison With Phase II and III Cases

“…12 The reports of SC cases that occur after trauma suggest an etiologic correlation between SC and trauma. [5][6][7][8] McCain and de la Rua 6 hypothesized that a traumatic experience could separate cartilaginous tissue into the joint space, where it might be captured in the synovial tissue. Subsequently, these fragments, receiving nutrients from the synovium layer, could overgrow and undergo calcification.…”

“…Cases of SC arising secondary to trauma [5][6][7][8] have been reported, of which some were found to be in phase III. 6,7 In addition, TMDs with clenching, clicking, or trismus are conditions that indicate the patient has chronic traumatic irritation.…”

Synovial Chondromatosis of the Temporomandibular Joint – Clinical, CT, MRI, Surgical and Histological Findings: Case Report

“…The etiology of SC has been related to the possible role of traumatic events [9]. Clinical and pathological findings obtained from imaging studies play an important role in the early diagnosis of SC.…”
