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.

摘要： 【摘要】 目的 筛选冠状切口术后颞部凹陷的相关危险因素。方法 收集采用冠状切口入路行眶颧复合体骨折修复术的87例患者作为观察对象,观察患者术后骨折复位及颞部凹陷情况,使用Logistic回归法对产生凹陷的危险因素进行筛选。结果 所有患者骨折愈合良好,但有11例在术后4~7个月出现颞部凹陷(占12.64%);受外伤至手术的时间、骨折类型、手术入路、颧骨体的移位、脂肪垫的移位或萎缩是术后颞部凹陷的危险因素(P<0.001,模型分类判对率超过85%)。结论 伤后早期手术、根据不同的骨折类型选择后合适的手术入路,术后加强随访明确骨体及脂肪垫的移位情况,可能有利于降低术后颞部凹陷的发生率。
