本文作者对12只猴右侧TMJ采取盘切除术、髁状突切除术、垂直升支切骨术,然后用颅骨肌筋膜瓣及颅骨瓣重建TMJ,在术后3d至78周进行临床组织学检查。 临床观察 12只猴术后均未发现有颌骨运动度降低、骨坏死、(牙合)关系改变、面部不对称及开口受限等症状。 组织学结果 术后3d:关节窝内的关节面正常,一部分内衬有滑液细胞,其他部分为纤维蛋白、红细胞和急性炎细胞。髁状突表面平坦,软骨缺如,骨表面缺乏成骨细胞,移植瓣水肿,内含有急性炎细胞和红细
In this study, we performed disc resection, condylar resection and vertical lumbar osteotomy on the right TMJ of 12 monkeys. TMJ was reconstructed with skull myofascial flap and skull flap. The clinical tissues School inspection. Clinical Observations None of the 12 monkeys had any symptoms of decreased mobility of the jaw, osteonecrosis, changes in occlusion, facial asymmetry and limited opening. Histological results 3d after surgery: articular surface within the joint fossa normal, some lined with synovial cells, the other parts of fibrin, red blood cells and acute inflammatory cells. Condylar surface flat, lack of cartilage, bone surface lack of osteoblasts, graft flap edema, which contains acute inflammatory cells and red fine
