The operation method of manual reduction: the patient sits in a low position with his head leaning against the back of the chair or the wall, and the occlusal surface of mandibular teeth should be lower than the elbow joint when the operator's arm is drooping. The operator stands in front, puts his thumb (which can be wrapped with gauze) on the occlusal surface of the mandibular molars on both sides, and the rest fingers hold the mandibular body. In the process of reduction, the patient is instructed to relax muscles, and the operator gradually presses down the back end of mandibular body with his thumbs. The rest of your fingers lift your chin slightly upward. When the condyle descends below the plane of articular tubercle, the mandible is pushed backward, and the condyle can slide back into the concave joint for reduction. Immediately after the reduction, the head and jaw bandages were used to fix it, and the mouth opening activity was restricted for about two weeks.
Attention should be paid to eliminating the patient's nervousness before reduction. Sometimes the temporalis and masseter muscles can be massaged, or the subtemporal trigeminal nerve or joint can be blocked with 1-2% procaine to help the old dislocation be reset. If necessary, it should be reset under general anesthesia or even open reduction.
