The temporomandibular joint is located in front of the ear screen on both sides and is one of the most delicate joints in the human body. However, some people suddenly find that the joints in front of the ear screen “click” when opening and closing the mouth, or the joints in front of the ear screen are painful when opening and closing the mouth, and some people suddenly can’t even do simple things like open their mouth! “This is temporomandibular joint disorder”! A mild displacement of the joint disk can be injected, wear jaw cushion treatment “temporomandibular joint and our daily eating and speaking open and close mouth movement is closely related to the temporomandibular joint disk forward displacement, it will cause open and close the mouth when the joint area ‘click’, and in serious cases will also cause open and close the mouth or bite when the joint In severe cases, it may cause pain in the joint area when opening and closing the mouth or when biting, and even the inability to open the mouth.” When TMJ problems occur, our daily life can be affected. ”To avoid these tragedies, it is important to take TMJ disorders seriously in the early stages of the disease. In the early stage of TMJ disorder, the treatment by injecting sodium hyaluronate gel into the joint cavity or wearing TMJ occlusion plate can get satisfactory results. However, when TMJ disorder develops to a later stage, the course of injection and joint plate treatment will be extended and the treatment effect will be slightly worse. ”TMJ endoscopy is the most advanced TMJ treatment technology at home and abroad, which can directly observe the tissue structure in TMJ, especially the situation of the joint disc and its adhesion degree, and is the gold standard for diagnosing TMJ disorders.” According to Zhang Qingbin, TMJ arthroscopy is used to diagnose and treat various joint diseases by cutting two chopstick cross-sectional size or smaller holes (5-10 mm) in the skin and inserting cameras and surgical instruments into the TMJ, which are operated by doctors under the monitoring of monitors. Through arthroscopy, surgical operations such as joint cavity irrigation, release of anterior joint band adhesions, joint disc repositioning, joint capsule tightening and removal of intra-articular synovial cartilage tumors can be performed under direct vision. Compared with traditional open surgery, arthroscopic minimally invasive surgery has small incision, less damage to surrounding tissues, shorter operation time, less bleeding, hidden scar, less complications, and can be performed under local anesthesia, so it is more easily accepted by patients.
