摘要：

目的: 回顾性分析颌面部电锯伤病例的临床资料，为此类外伤的防治提供依据。方法: 通过回顾2022年1月至2023年1月四川大学华西口腔医院急诊科收治的颌面部电锯伤患者7例，收集人口学变量、伤口相关变量、治疗相关变量、术后愈合特征变量，分析颌面部电锯伤的发病机制及诊疗经验。结果: 77.78%（7/9）的伤口在伤后6 h行清创缝合术，所有患者均于伤后10 h内完成Ⅰ期缝合术。术后积极进行健康教育及居家伤口护理指导，其中，6例患者术后伤口愈合良好，1例患者合并右眼永久性失明，1例患者并发术后感染。结论: 针对颌面部电锯伤，应建立多维度防控策略以规范电锯工种职业行为，降低其发生率。一旦发生颌面部电锯伤，医疗人员及患者应积极应对以降低术后重要器官功能受损及相关并发症的发生率。

Abstract:

Objective: To retrospectively analyze the clinical data of maxillofacial chainsaw injuries, and provide the basis for the prevention and treatment of maxillofacial chainsaw injury. Methods: Seven patients with maxillofacial trauma caused by chainsaw that visited the Emergency Department of West China Hospital of Stomatology, Sichuan University from Jan 2022 to Jan 2023 were included. Demographic information, wound variables, treatments, and postoperative healing characteristics were collected to analyze the pathogenesis and summarize the treatment experience of maxillofacial chainsaw injury. Results: All patients underwent first-stage debridement and suture within 10 hours after injuries, among which 77.78% (7/9) of them underwent debridement and suture within 6 hours after injuries. The health education and wound nursing management were conducted postoperatively. Post-treatment wound healing was satisficed in 6 patients, while one patient had permanent right eye blindness, and one patient suffered wound infection after treatment, Conclusion: Multidimensional prevention strategies should be established to standardize the practice behavior of chainsaw and reduce the incidence of maxillofacial trauma caused by chainsaw. Came to an emergency, medical staffs and patients should take active measures to reduce the incidence of postoperative vital organ function impairment and complications.
