Line with the temporomandibular joint cartilage ribs area growth and its influence factors after transplantation of animal experiments

tomato1) 2003Nov, 19 (6) Figure 2A 6-week group transplanted with normal condylar cartilage of the ribs have begun to take the form of HE (× 17. 5) 6 weeks after operation Figure 3D side of a bone active operation, enhance or support stump new trabecular bone and cartilage due to the emergence of smooth changes, the top of condyle and the nodules occur between the parallel fibers. . HE (× 35) 3 discussions 3.1CCG impact of transplantation on facial growth period in the growth and development of temporomandibular joint ankylosis caused by condylar growth center in the loss of ipsilateral mandibular disorders appears to produce micrognathia. CCG-line autologous TMJ arthroplasty, cartilage and a bone growth center junction may have growth capacity, to prevent the occurrence of maxillofacial deformities. After surgery were side of the mandible appears to reduce the height, A,[link widoczny dla zalogowanych], B,[link widoczny dla zalogowanych], C group deformity from light to heavy. Cephalometric Results The patients in group C and non-operated side mandibular lateral height of the maximum of absolute differences, corresponding to the most obvious of maxillofacial deformities. Support the role of selection can be seen with good growth potential and has a self CCG temporomandibular joint reconstruction after surgery for the improvement of deformity does help. 3.2 The length of the mandibular costochondral term effects of a high degree of Histology showed A (long cartilage) and bone formation activity was stronger than B (short cartilage), X Cephalometric operated side and non-technical side of the mandible height difference small, no significant difference, and B (short cartilage) height difference between both sides of the mandible large, there is statistically significant. Tip over a long cartilage group with the strongest growth trends in recent _3]. Long cartilage graft arthroplasty will result in over-development of the operative side mandibular need longer observation. 3.3 condylar metaplasia in the stimulation of chewing function, CCG cartilage surface of new cartilage, new bone trabecula cartilage deep to appear after 6 weeks CCG has a condylar morphology, histological structure similar to the normal condyle . C group bone stump by new bone and cartilage tends to smooth, and joint tubercle parallel between the top of the fiber occurs, gradually tend to condylar shape. This organization phenomena and Tai Zhen Xing with coracoid joint ankylosis surgery for histopathologic observation of similar. 3.4 implants and histological changes during alterations r rib cartilage growth centers are usually near the junction of a rib cartilage. After 4 weeks, A, B2 group CCG cartilage chondrocytes of proliferating cells near the junction of the ribs, after 6 weeks of new proliferating cells have been close to the articular surface,[link widoczny dla zalogowanych], tends to level-like arrangement. Tip rib cartilage transplant in the germinal center area after TMJ condyle occurred in similar histological changes. CCG ascending branch of the Ministry of bone trabecular bone fusion, strengthening the stability of the implant. CCG fibrous tissue adjacent to the cartilage surface clutter by a loose arrangement to regular compact arrangement, and may integrate into the cartilage surface of the fibrous cartilage layer, cartilage implants increase the compression and wear resistance. In summary,[link widoczny dla zalogowanych], CCG is superior to other implants (coracoid process, posterior mandible, etc.), in addition to the performance of articular cartilage is not easy and the concave wall of bone adhesion, easy shaping, the biggest advantages are: cartilage growth centers can in the functional stimulation to Ruan Gutou into a similar structure and shape of condyle and facial deformity with continued growth potential for improvement, it is widely used in clinical,[link widoczny dla zalogowanych], but the length of the CCG best cartilage needs further study.
