Objective To evaluate the effect and feasibility of external drainage for drilling traumatic epidural hematoma in the posterior cranial fossa .Methods The children in our hospital with traumatic unilateral posterior fossa epidural hematoma from June 2007 to June 2016 were all treated with drilling drainage ,hematoma suction ,drainage with 48-72 hours .Results There were 20 cases of pediatric patients in this study .Over 90％ hematoma eliminated in 15 cases ,and over 80％ hematoma eliminated in 5 cases .The operation time was 40-50 minutes ,the clinical symptoms of pediatric patients were improved after surgery ,with no seri-ous complications .They were all cured ,the average hospitalization days was 11 days .Conclusion Drilling and drainage is an effec-tive ,rapid ,safe and very small traumatic operation for the treatment of unilateral epidural hematoma in children's traumatic cranial fossa .%目的 探讨儿童创伤性后颅窝硬膜外血肿经钻孔外引流治疗的有效性和可行性.方法 选取北大医疗集团平顶山中心医院2007-06—2016-06收治的儿童创伤性后颅窝单侧硬膜外血肿患者,均行钻孔外引流术,术中吸除大部分血肿,放置引流管,引流48～72 h.结果 本组20例儿童患者,15例血肿消除90％ 以上,5例血肿消除80％ 以上,手术时间40～50 m in,术后儿童患者临床症状改善明显,无严重并发症和后遗症,20例均治愈出院,平均住院时间11 d.结论 钻孔引流治疗儿童创伤性后颅窝单侧硬膜外血肿是一种有效、快速、安全、创伤性非常小的手术方法.
