joint nodule reduction

Articular nodule reduction is a surgical procedure used in the past to treat recurrent temporomandibular joint dislocation, mainly to limit the activity of the condyle. The joint nodule reduction was first proposed by Myrhang in 1951. The focus of the operation was to form a shallow joint socket and reduce the height of the joint nodule so that the condyle can be self-resetting without being blocked when the mandibular joint is dislocated. In recent years, it has also achieved good results in the treatment of temporomandibular joint disorder syndrome. Temporomandibular joint structure. Treatment of diseases: temporomandibular joint dislocation Indication 1. Recurrent temporomandibular joint dislocation. 2. Temporomandibular joint intractable pain amating. Contraindications Not suitable for excessive activity of the condylar process caused by muscle and mental factors. Preoperative preparation 1. For clinical and X-ray examination, clear diagnosis. 2. The skin is routinely prepared for 10cm around the ear. Surgical procedure 1. Incision and exposure Make a cane-shaped incision in front of the ear to expose the joint capsule. After clearing the position of the joint nodules, the temporomandibular ligament is turned down, the periosteum of the zygomatic arch is cut, and the epithelium is exfoliated to expose the superior cavity of the joint, and then the anterior iliac crest is attached, and the joint nodules are completely exposed. 2. Resection of joint nodules A small ball is drilled on the base of the joint nodule as a row of holes parallel to the lower edge of the zygomatic arch. The holes are connected by a split drill, and then the osteotome is used to cut the joint nodules from the lateral side to the inside. The bone section is trimmed and smoothed with the epiphysis. 3. Suture the wound Rinse, stop bleeding, stratify the wound, place a drainage strip, and compress the dressing. complication If the joint nodule radiograph shows excessive gasification (indicating that the blood vessels are rich), removal of the joint nodules may present a potential risk of intracranial infection and bleeding.
