A patient was seen in the outpatient clinic today, primarily for maxillofacial discomfort to the surgery department. MRI showed displacement of the articular disc and the surgeon recommended surgery. The patient and his family were hospitalized for the surgery, but in the early morning of the day of the surgery, the patient and his family came to our department after learning about conservative treatment options. Many patients have little knowledge of TMJ dysfunction, and after a surgical visit, most physicians recommend surgery if there are anatomical changes such as displacement of the articular disc. However, the core of today’s overall TMD treatment plan is to restore the patient’s joint function and quality of life, rather than to “restore the normal position of the joint disc” as the ultimate goal of treatment. Therefore, we emphasize the principle of “individualized” treatment, i.e., to develop an appropriate and specific treatment plan according to each patient’s specific situation, to give priority to the principle of improving the patient’s quality of life and restoring joint function, and to adhere to the principle of reversible, non-invasive or minimally invasive non-surgical treatment for the patient. Therefore, for patients with temporomandibular joint dysfunction, it is recommended to try formal conservative treatment first. It is not only the injection or medication that is called treatment, but our conservative treatment includes the adjustment of patient’s behavior, diet, posture education, physical factor treatment, manipulation, functional training and so on. Most of the patients have different degrees of improvement in their symptoms after regular conservative treatment. Even if the results of conservative treatment are not satisfactory, there are still opportunities for surgery.
