All the value of complications occurs in the patients from out side the Mosul city. More complications occur in the body of the mandible in which the percentage was 5 from the total complications so we found a 2  significant percentage here one related to the frequency of the fracture in which the more site of fractures found in the angle while the more site of complications in the body. The more complications occur in the fracture caused by missile injury. All the complications associated with missile ,We found more complication in the workers patients than another patients. 30 cases was operated by extraoral approach & 6 of them has complications & 4 of the cases was operated by intraoral approach one of them has a complication & 30 cases was operated by extraoral approach & 6 of them has complications & 4 of the cases was operated by intraoral approach one of them has a complication.
