Twelve adult mongrel dogs were divided into two groups and were used in this study; to compare and to evaluate histologically in 3 months period; unilateral replacement of the dogs meniscus of temporomandibular joint with either autogenous cartilage of their external ears or with Zenoderm heterogeneous graft. Autogenous cartilage of the dogs ear was progressively replaced by fibrous tissue and its attachment to the lateral pterygoid muscle was started at the third month postoperatively. On the other hand, Zenoderm was replaced by vascular fibrous tissue and begun to attach to the lateral pterygoid muscle from the first month postoperatively and showed also good functional adaptation to the bony surfaces. In both grafts there were no changes of the bone architecture.
12只成年杂种犬被分为两组用于本研究;在3个月的时间里进行组织学比较和评估;用犬的外耳自体软骨或Zenoderm异种移植物单侧替换犬颞下颌关节的半月板。犬耳的自体软骨逐渐被纤维组织取代,其与翼外肌的附着在术后第三个月开始。另一方面,Zenoderm被血管纤维组织取代,从术后第一个月开始与翼外肌附着,并且对骨表面也表现出良好的功能适应性。两种移植物中骨结构均无变化。
