Objective: This study aimed to investigate clinical efficacy of a modified coronal approach in treatment of craniomaxillofacial fractures.
Methods: Thirty-seven cases of craniomaxillofacial fractures underwent open reduction and rigid internal fixation through modified coronal approach. Clinical follow-up visits were conducted to evaluate facial nerve functional status, temporal shape, appearance restoration, and reduction of fracture and surgical area scars.
Results: During follow-up period of 6-36 months, appearance and function of all 37 patients recovered well without facial nerve injury and temporal depression deformity. All cases presented hidden scars, except for one case with hypertrophic scar.
Conclusions: Applying modified coronal approach to craniomaxillofacial surgery effectively reduces incidence of temporal depression and facial nerve injury compared with traditional approach. The modified coronal approach produced more subtle scars compared with traditional approach and should be applied to treatment of craniomaxillofacial fractures.
目的 探讨一种新的改良头皮冠状切口在颅颌面骨折手术中的应用价值。方法 对37例颅颌面骨折患者采用改良头皮冠状切口进行颅颌面骨折的修复重建。术后对患者面神经功能状况、耳颞区形态、面形恢复、骨折复位、术区瘢痕等方面进行评价。结果 术后随访6~36个月，37例患者均未出现面神经功能损伤和耳颞区凹陷，面形恢复良好，骨折端均实现解剖复位。切口瘢痕隐蔽，1例出现增生性瘢痕。结论 改良头皮冠状切口可有效降低传统冠状切口所导致的颞区凹陷及面神经颞支损伤的发生，切口更隐蔽，未增加其他并发症的发生，值得临床推广。.
