观察慢性硬膜下血肿患者行封闭式颅骨钻孔引流术的疗效。

选取自2012年6月至2016年6月解放军第四一三医院收治的慢性硬膜下血肿患者63例为研究对象，分为传统钻孔引流术（传统组）和封闭式钻孔引流术（封闭组）2种手术方式，对2组的疗效及手术并发症进行比较分析。

2组手术方式均获得满意的疗效，治疗效果差异无统计学意义（Z=1.685，P>0.05）；封闭组术后颅内积气（χ²=4.893，P<0.05）、脑损伤（χ²=4.784，P<0.05）、切口脑脊液漏（χ²=6.003，P<0.05）的发生率明显低于传统组，差异有统计学意义；2组术后硬膜下积液（χ²=0.001，P>0.05）、癫痫发作（χ²=0.000，P>0.05）、血肿复发（χ²=0.001，P>0.05）的发生率差异无统计学意义。

在慢性硬膜下血肿钻孔引流治疗中，封闭式钻孔引流术较传统钻孔引流术能明显降低并发症的发生率，引流途径安全有效，是治疗慢性硬膜下血肿理想的一种手术方式。

To observe the clinical effect of closed burr hole drainage on patients with chronic subdural hematoma (CSDH).

Sixty-three CSDH patients treated in the 413rd Hospital of PLA from June 2012 to June 2016 was observed in this study. According to the operation method, patients were divided into two groups: the traditional burr hole group and the closed burr hole group. The curative effects and the operative complications were compared and analyzed.

The curative effects were both satisfactory, and there was no significant different between the two groups (Z=1.685, P>0.05). The incidence of intracranial pneumatocele (χ²=4.893, P<0.05), brain injury (χ²=4.784, P<0.05) and leakage of cerebrospinal fluid (χ²=6.003, P<0.05) in the closed burr hole drainage group were significantly lower than those of traditional group. There were no significant difference of incidence of subdural fluid accumulation (χ²=0.001, P>0.05), epileptic seizure (χ²=0.000, P>0.05) and hematoma recurrence (χ²=0.001, P>0.05) between the two groups.

In treating CSDH, closed burr hole drainage is an ideal method which can significantly lower the operative complications and achieve good curative effect.
