本文研究耳软骨移植在羊颞下颌关节(temporomandibular joint,TMJ)关节炎进程中的作用。 材料与方法 4只60kg重的羊,麻醉后测其最大张口度及下颌侧向移动度。手术去除髁突表面纤维软骨组织,引发关节内炎症。3个月后,取右耳耳软骨,修剪适当植入右TMJ。测量4个移植软骨和右关节盘的厚度。术后3个月,测4只羊最大张口度及下颌侧向移动度。麻醉致死,取双侧TMJ观察。行水平及矢状方向
This article studies the role of otic cartilage transplantation in the progression of arthritis in the temporomandibular joint (TMJ). Materials and methods 4 60kg heavy sheep, measured after anesthesia maximum mouth opening and lateral mandibular movement. Surgical removal of the surface of the condylar cartilage tissue, triggering intra-articular inflammation. After 3 months, remove the right ear cartilage and trim the right TMJ properly. The thickness of the four grafted cartilage and right disc was measured. Three months after operation, the maximum mouth opening and mandibular lateral movement of 4 sheep were measured. Narcotic lethal, bilateral TMJ observation. Row level and sagittal direction
