영문 초록

The purpose of this study was to investigate the effect of muscle impingement to healing process of the fractured bone. For the purpose, the mandibular angle area of eight rabbit were used. In the experimental group the defects were made with 1㎜, 3㎜, and 6㎜, width and 10㎜ height, then the masseter muscle flaps were impinged in the defects and sutured with internal pterygoid muscles. In the control group the defects were made only as same manner on the opposite site. The experimental animals were sacrificed at 4 weeks after surgery and the operation sites were examined under the light microscope to observe the bony repair process histopathologically. The results obtained from this study were as follows: 1. The impinged muscular tissues were disparted and released by ribroblasts and collagen cell regeneration, but not resorpted. 2. Both fractured ends were united by collagen fibers containing muscular fibers. 3. New bone formation was observed under the bony cutting ends and cortical layers. 4. There are no remarkable differencies in the histologic changes of the healing processes according to the amount of the bony defects. 5. Large quantities of bony callus formation were observed in the bony defected portions of the control group.
