temporomandibular joint examination

The temporomandibular joint examination is used for the diagnosis of temporomandibular joint disorder syndrome. The normality of joint movement function is judged by the examination of the facial shape, opening degree and opening limit, and masticatory muscles. The two fingers of the little finger were inserted into the external auditory canal, palpate to the front, and the two hands were placed in front of the tragus on both sides. The patient was opened and closed to check the movement of the condyle and the presence or absence of squeaking and friction. Do not exercise vigorously the day before the test to prevent damage to the face joints, so rest well. Basic Information Specialist classification: growth and development check classification: physical examination Applicable gender: whether men and women apply fasting: not fasting Tips: Do not exercise vigorously the day before the check to prevent damage to the face joints, so rest well. Normal value Muscle muscles such as diaphragm, masseter muscle, and extra-pterygic muscle have strong contractile force, no tenderness, bilateral symmetry, normal opening and opening type, uniform joint motion on both sides, no squeaking and noise, and bilateral symmetry The joint area, the mandibular angle, the mandibular branch and the mandibular body are normal in size and length, bilaterally symmetrical; the sacral point is centered, and the subsurface is coordinated by l/3. Clinical significance Abnormal results: The contraction force of the muscles of the diaphragm, masseter muscle, and extra-pterygic muscle is not good. It is tender and bilaterally asymmetrical, indicating that the masticatory muscle contraction force is impaired; the opening degree and the opening type are abnormal, and the bilateral joint motion is inconsistent. There are squeaking and murmurs, indicating mandibular motor dysfunction; the left and right sides are not symmetrical, including the joint area, the mandibular angle, the mandibular branch and the mandibular body are not normal in size and length, bilateral asymmetry; the sacral point is not centered, subsurface L/3 is uncoordinated, indicating damage to the face joints. Need to check the population of patients with temporomandibular joint disorders, temporomandibular joint dislocation. Precautions Taboo before the test: Do not exercise vigorously the day before the test to prevent damage to the face joints, so rest well. Requirements for inspection: Follow the instructions of the doctor for the operation of the action specification. Inspection process The two fingers of the little finger were inserted into the external auditory canal, palpate to the front, and the two hands were placed in front of the tragus on both sides. The patient was opened and closed to check the movement of the condyle and the presence or absence of squeaking and friction. In addition, it is necessary to check whether the left and right sides of the face are symmetrical, whether the mandibular parts are deformed, whether the midpoint is centered, whether the joint areas and the masticatory muscles are tender, whether the mandibular movement is skewed, and whether the occlusal relationship is good. Not suitable for the crowd Inappropriate crowd: None.
