Objective: To investigate the causes and to propose preventive measures analysis of mandibular angle plasty and postoperative complications occurred . Methods: 60 cases of the mandibular angle angioplasty cases from 2006 to 2009 . Surgery is divided into three , to improve the mandibular branch sagittal split osteotomy II mandibular angle wedge osteotomy , three mandibular angle continuous curved osteotomy . Surgery and postoperative complications are summarized, and analysis of its causes , and to propose preventive measures . Results: In addition to a case of postoperative right mandibular angle is too large , underwent secondary surgery treatment , the remaining patients recovered well , the postoperative facial contours to improve satisfaction . Follow - up time of 3-24 months , with an average of 12 months. Two cases of facial artery rupture led to bleeding in surgery , facial artery ligation , bandaged uneventful recovery . Four patients wound oozing excessive coagulation surgery to stop bleeding , postoperative hemostatic agents , blood transfusion and pressure bandage improved after treatment . 1 case occurred in the inferior alveolar nerve transection . 1 patient perioral soft tissue injury , recovery after appropriate treatment . Three cases of postoperative hematoma after clearing after a good recovery . Two cases of postoperative lower lip paresthesia, about two months after surgery to restore their own . 8 cases of postoperative mouth askew , are in the three months after their own recovery . After removal of wisdom teeth pericoronitis triggered jaw abscess after debridement and drainage anti-inflammatory treatment , healing well . Conclusion : The surgical area complex anatomical structures , narrow surgical field , on the technical requirements of the surgeon , and prone to complications . Surgery , one of the highest risk orthopedic surgery . Requiring the surgeon to have a skilled surgical techniques , and appropriate osteotomy , widely separated subperiosteal soft tissue , perioral soft tissue gentle traction after properly bandaged , continuous suction drainage and other measures can be avoided and reduce complications place.
