The main cause believed to be metaplasia embryonal mesenchymal membrane. metaplastic foci grow within joint space and can detach from wall, forming free-floating bodies. While SC more commonly associated with trauma temporomandibular (TMJ), exact relationship between remains unclear. Improved diagnostic techniques, such CT MRI, have led increased recognition TMJ. Gender differences prevalence TMJ been observed, women being affected. Diagnosis involves imaging techniques like X-rays, scans, MRIs, surgical removal loose bodies preferred treatment. Arthroscopy recommended for small, isolated bodies, while open surgery may necessary complete removal. Long-term follow-up essential monitor recurrence.
