Abstract: 【Abstract】Objective To screen the related risk factors for postoperative temporal depression by coronary incision. Methods The clinical data was collected from 87 patients underwent surgical treatment of orbitozygomatic complex fracture repair through coronary incision approach from Jan 2001 to Dec 2010..The postoperative fracture reduction and temporal depression were observed and analyzed. The risk factors of postoperative local sag was analyzed by using Logistic regression method. Results All patients with orbitozygomatic complex fracture healed but temporal depression occurred in 11 cases (12.64%) in 4-7 months after operation. The time from trauma to the surgery, fracture type, surgical approach,.zygomatic body shift,.fat pad of the shift or contract were risk factor for postoperative temporal depression (all P<0.001, classification and model of rate of more than 85%). Conclusion Early operation after injury,.selection of appropriate surgical approach,.postoperative follow-up for shift situation of bone mass and fat pad,.are expected to reduce the incidence of postoperative temporal depression.
