When mandibular joint disorder syndrome occurs, most patients can usually be cured with prompt treatment. When temporomandibular joint disorder syndrome occurs, it is important to seek prompt medical attention, which is usually recommended within 3 months. When TMJ disorders are less than 3 months old, they are usually in the acute phase, where the chances of recovery through conservative treatment are more than 80%. When not seen immediately, the temporomandibular joints may show organic changes in the internal structures of the joints in addition to functional disorders, which may require the use of surgery. Minimally invasive TMJ arthroscopic surgery is less invasive and has a higher surgical cure rate, making it a better treatment option. For patients with more severe symptoms, open surgery may be required to completely repair the temporomandibular joint in order to facilitate the return of the patient’s joint structure and function to normal. Therefore, when jaw joint disorder syndrome occurs, it is necessary to do timely medical examination.
