Abstract

Abstract:

Objective To summarize the clinical significance of arthroscopy in the diagnosis and treatment of temporomandibular joint synovial chondromatosis(TMJ SC). Methods Seventeen cases with TMJ SC who were surgically treated by arthroscopy from September 2020 to September 2024 in The Peking University Stomatological Hospital were retrospectively analyzed. Data including preoperative examination, maximum incisal opening(MIO), and visual analog pain score(VAS) were analyzed and summarized. Results All the 17 TMJ SC cases were treated by arthroscopy, consistent with the postoperative pathological diagnosis. Postoperative review by MRI showed that joint cavity lesions disappeared. No recurrence was observed during postoperative follow-up, and clinical symptoms were improved to varying degrees. Conclusion For TMJ SC, arthroscopic surgery has advantages such as minimal trauma and wide indications, which can effectively alleviate clinical symptoms, improve temporomandibular function, and reduce the occurrence of postoperative complications.

Key words: temporomandibular joint, synovial chondromatosis, arthroscopic surgery
