With the object of studying the need of disc replacement after meniscectomy and the biocompatibility of the autogenous auricular cartilage as a disc replacement histologically, the author made this research. The experimental materials were 17 male rabbits aging 10weeks and weighing 1.5kg. The control group was not surgically treated and the experimental groups were surgically treated. -meniscectomy only on the left TMJ, and autogenous auricular cartilage graft as a disc replacement after meniscectomy on the right TMJ. The experimental groups were devided into 4 groups and each group was consisted of 4 rabbits. Each group was sacrificed after 2weeks, 4weeks, 12weeks, 24weeks after surgery. The temporomandibular joints and their surrounding tissues were obtained to microscopic specimens stained with Hematoxylin- Eosin method. The specimens were examined under light microscope. The results were as follows;
1. The sites which were menisectomized only.
Osteoarthrosis that is to say decreased cellular components and cartilaginous layer with bony erosion was seen on the functional portion(loaded portion). Remodeling with cartilaginous proliferation was seen on the nonfunctional portion(unloaded portion). On the whole osteoarthorosis and remodeling with deformation was seen.
2. The sites which menisectomy and auricular cartilage graft was done.
Slight cartilaginous layer atrophy and bone resorption were seen but maintained relatively normal temporomandibular joint form. The grafted auricular cartilages were considerably displaced but they were viable and there were no adhesions or other specific abnormalities. But the uncovered portion showed partial erosion.
3. The author concluded that replacing after menisectomy was more effective and autogenous aruicular cartilage was useful for that purpose. And fixing firmly not to displace was very important for good results.
