对下颌骨囊肿摘除后的大型骨腔的处理有多种方法,Richter等(J Oral Maxillofac Surg 44:447,1986)采用经—20℃低温处理的同种异体松质骨填充这类骨腔,经33例临床应用和远期观察,证明效果良好。供骨源为漕受髋骨骨折而需关节置换的老年患者之股骨头。切取的股骨头放入广口瓶内旋紧瓶盖置于—20℃的条件下冷冻。处理后3周～1年内应用。应用时在无菌条件下制备移植体。先将股骨头劈开,用骨钳取下松质骨并放入微热的新霉素溶液中。随后尽可能将骨松质剪碎,用新霉素溶液冲洗后通过较小的手压挤出其中液体。用充填器将松质骨碎片分层填入颌骨囊肿摘除后的
There are several ways to handle large bone cavities after removal of the mandibular cyst. Richter et al. (J Oral Maxillofac Surg 44: 447, 1986) filled these bony cavities with allogeneic cancellous bone treated at -20 ° C, After 33 cases of clinical application and long-term observation, the effect is proved to be good. Bone for the bone source for the hip by hip fracture and joint replacement of the elderly patients with the femoral head. Cut the femoral head into the jar and tighten the cap at -20 ℃ under the conditions of freezing. 3 weeks after treatment ~ 1 year application. Grafts are prepared under aseptic conditions for use. First split the femoral head, remove the cancellous bone with bone forceps and put in a solution of neomycin fever. Afterwards, as much as possible, the cancellous bone was cut, and the liquid was squeezed out by a small hand pressure after rinsing with a neomycin solution. Loose bone fragments will be layered filled with popliteal jaw cyst removed
