Abstract:

Objective To investigate the application of arthroscope in the surgical treatment of the patients with temporomandibular joint synovial osteoma disease， and to clarify its value in improving the clinical diagnosis and treatment efficiency and prognosis of the patients with the disease. Methods The clinical data of two patients with temporomandibular synovial osteoma disease treated with arthroscope were collected.The opening degree， maximum anterior extension and lateral movements， and pain improvement of the patients were compared before and 6 months after surgery， and the operation procedure was summarized，and the significance of arthroscope application was analyzed combined with literature review. Results Two patients with temporomandibular synovial osteoma disease both chose the method of open surgery combined with arthroscope.With the assistance of arthroscope， the open surgery completely removed the chondroma bodies， and the removal of inflammatory synovial tissue was carried out.The opening degrees of the patients reached 33 and 35 mm， respectively， 6 months after operation， and the maximum anterior extension and lateral movement were ≥7 mm，the joint function was gradually restored. Conclusion Arthroscope has obvious advantages in the surgical treatment of the patients with temporomandibular synovial osteoma disease， but fully arthroscopic surgery is limited by the complex structure of the joint， and if the tumor is too large or not confined to the supra-articular cavity， open surgery combined with arthroscope is required when necessary.
