１２只成年杂种犬按以颞肌为供血蒂的下颌骨升枝骨肌瓣和下颌骨升枝骨块游离移植分组，分别修复同侧上颌骨或颧弓缺损。结果：移植的骨块均生长良好，无坏死表现。用下颌升枝骨块修复颧弓缺损厚度适宜，恢复外形最佳。颧肌部分做为供血蒂后，其余部分组织学观察无明显改变。利用下颌骨升枝为供骨源修复上颌骨或颧弓缺损，就近取材，血供良好，成活率高，手术易行，操作简便，是种可供临床应用新的修复方法。
Twelve adult mongrel dogs were divided into two groups according to the grafts of mandibular grafting myocutaneous muscle and the mandibular lumbar intervertebralis grafting by the temporalis muscle as the donor pedicle, respectively, to repair the ipsilateral maxillary or zygomatic arch defects. Results: The transplanted bone all grew well without necrosis. With mandibular lumbar bone repair zygomatic arch defect thickness appropriate to restore the best shape. Zygomatic muscle part as a pedicle, the rest of the histological observation no significant change. The use of mandibular ligation of the bone for the repair of the maxillary or zygomatic arch defect, the recent draw, blood supply is good, high survival rate, easy operation, easy to operate, is a new clinical application of repair methods.
