目的探讨单骨孔与双骨孔技术治疗慢性硬膜下血肿的临床疗效。方法选取我院50例慢性硬膜下血肿患者，按照数字随机法随机分为两组，观察组采用双骨孔技术治疗，对照组采用单骨孔技术治疗，观察两组患者血肿清除情况、平均住院时间、并发症发生情况等。结果观察组22例血肿被清除，清除率88.0%；部分清除3例，清除率为12.0%，无死亡病例；术后并发症发生率为8.0%（2/25），分别为脑脊液漏1例和癫痫发作，无张力性气颅发生和精神障碍出现；患者平均住院时间为（5.9±3.1）d；对照组19例血肿被清除，清除率76.0%，血肿部分清除5例，清除率为20.0%，有1例出现死亡；术后并发症发生率为28.0%（7/25），其中脑脊液漏2例，癫痫发作3例，精神障碍1例，张力性气颅1例；患者平均住院时间为（11.1±3.9）d。以上数据两组相比，差异均有统计学意义，P﹤0.05。结论双骨孔技术治疗慢性硬膜下血肿疗效显著，血肿清除率高，损伤小且并发症少，可作为外科治疗慢性硬膜下血肿的一种较理想的手术方式。“,” Objective: To study the single and double bone bone hole hole technique treatment the clinical curative effect of chronic subdural hematoma. Selection methods: 50 patients with chronic subdural hematoma patients, according to the figures a random method randomly divided into two groups: observation group with double hole technology treatment, control group adopts single bone hole technology treatment, observe two groups of patients with hematoma removal of conditions, the average length of hospital stay, complications, etc. Results: the observation group and 22 cases of hematoma removal, clearance rate 88.0%; Part 3 cases, clearance rate was 12.0%, without death cases; The incidence of postoperative complications was 8.0% (2/25), respectively, cerebrospinal fluid leakage in 1 case and epileptic seizures, without tension chi cranial and mental disorders; Patients with an average length of hospital stay (5.9 + 3.1) d; Clearance rate 76.0%, control group 19 cases of hematoma is cleared haematoma part in 5 cases, clearance rate was 20.0%, 1 case appeared died; The incidence of postoperative complications was 28.0% (7/25), of which the cerebrospinal fluid leak in 2 cases, seizures (3 cases), psychiatric disorders in 1 case, tension chi skul in 1 case; Patients with an average length of hospital stay (11.1 + 3.9) as d. Above data compared two groups, difference have statistical significance, P ﹤ 0.05). Conclusion: double bone hole technique has a good effect for the treatment of chronic subdural hematoma, hematoma clearance rate is high, less injury and less complications, can be used as a surgical treatment of chronic subdural hematoma is an ideal operation method.
