目的 对治疗慢性硬膜下血肿患者应用小骨窗开颅血肿清除以及钻孔引流治疗后患者症状改善以及手术后出现复发情况进行对比研究分析。方法 选取2014年1月—2020年3月间进行治疗的慢性硬膜下血肿患者共85例作为研究分析对象,根据患者所用治疗方式分为观察组、对照组。观察组患者应用骨窗开颅手术治疗,对照组患者应用钻孔引流手术治疗,对比两组患者手术对症状的影响以及手术后出现复发情况。结果 两组患者经过手术治疗后在症状改善方面,无明显差异（P>0.05）。两组患者在手术后出现并发症方面,无明显差异。在手术后出现复发情况方面,观察组患者明显低于对照组,差异有统计学意义（P<0.05）。结论 治疗慢性硬膜下血肿患者应用小骨窗开颅血肿清除以及钻孔引流治疗均有一定的治疗效果,可有效缓解患者症状,其中小骨窗开颅血肿清除治疗方式后患者出现复发概率更低,在临床治疗中值得推广应用。

Objective To compare and analyze the symptoms of patients with chronic subdural hematoma treated with small bone window craniotomy hematoma removal and drilling and drainage, and the recurrence after surgery. Method A total of 85 patients with chronic subdural hematoma treated in our hospital from January 2014 to March 2020 were selected as study subjects, and divided into an observation group and a control group according to the treatment Methods provided. The observation group was treated with in-window craniotomy, while the control group was treated with drilling and drainage surgery. Comparisons of the symptoms and recurrence were made between of the two groups. Results There was no significant difference in symptom improvement between the two groups of patients after respective surgical treatments (P>0.05); there was also no significant difference in the incidence of complications after surgery between the two groups of patients. The observation group showed a significantly lower recurrence rate than the control group (P<0.05). Conclusion Both small bone window craniotomy hematoma removal and drilling and drainage have certain therapeutic effects on chronic subdural hematoma, and effectively alleviate patient’s symptoms. Small bone window craniotomy hematoma removal can produce a lower recurrence rate; therefore, it is worthy of popularization and application in clinical treatment.
