Objective:To elaluate the clinical factors related to the failing of mandibular reconstruction by bone transplantation after partial dissection of mandible and methods to avoid that.Method: 126patients underwent mandibular reconstruction by bone transplantation after partial dissection of mandible in the school of stomatology of Wu Han University during 1999.1 to 2003.8 were selection for research. The clinical factors related to the failing in 4 cases out of the 126 cases were analysed.Result:4 out of the 126cases were failure.It was found that the failing in 2 cases was related to the crack of the oral mucosal wound after operation. One case was related to the looseness of the totanic serews. AII of the three patients underwent operations to harvest the transplantive bones 1 month after the first operations. One case showed the infection after the crack of the lingual mucosa and the dead bone was scraped after 3 months.Conclusion: The factors related to the failing of mandibular reconstruction by bone transplantation after partial dissection of mandible are including infection、 unconnection of the bone and the crack of the wound.
