First of all, you should go to stomatology for treatment, because temporomandibular joint is divided into upper cavity and lower cavity, and hyaluronic acid or sodium hyaluronate is usually injected into the lower cavity, that is, between the articular surface of condyle and articular disc. I haven't heard that it can be injected into the inferior cavity in orthopedics.

Follow-up treatment can do some physical therapy appropriately, and the symptoms will gradually improve. In addition, it is necessary to check whether there are bone fragments in the joint cavity, which is technically called joint rat. If there are joint mice, they need arthroscopic treatment. Arthroscopic surgery is very difficult. If you are in Wenzhou, it is recommended to consult Zhejiang First/Second Hospital.
