目的通过手术前后腰大池持续引流,观察大中型听神经瘤患者显微外科手术治疗的疗效,探讨腰大池持续引流在大中型听神经瘤显微外科手术治疗中的临床意义。方法对59例听神经瘤患者随机分为实验组22例和常规组37例。实验组:术前、中、后使用腰大池持续引流;常规组:术中枕大池释放脑脊液,两组手术方式及术后常规治疗方案均相同,比较两组肿瘤全切率、面神经解剖保留率,平均手术用时。结果两组面神经保留率分别为19例/22例(86.40%),22例/37例(59.50%),(χ2=4.71,P<0.05),肿瘤全切率分别为20例/22例(90.90%),25例/37例67.60%,(χ2=4 15,P<0.05),两组有统计学意义;两组平均手术用时h:(2.6±0.5)和(3.3±0.6),(t=4.60,P<0.01),有统计学意义。结论腰大池持续引流在大中型听神经瘤显微外科手术治疗中的临床意义显著,治疗组优于常规治疗组。
Objective To observe the clinical effect of microsurgical operation in patients with large and medium sized acoustic neuroma by continuous drainage of the lumbar cistern before and after operation and to investigate the clinical significance of continuous drainage of the lumbar cistern in the treatment of large and medium sized acoustic neuroma by microsurgery. Methods Fifty-nine patients with acoustic neuroma were randomly divided into experimental group (n = 22) and conventional group (n = 37). In the experimental group, the lumbar pool was used for continuous drainage before, during and after the operation. In the conventional group, cerebrospinal fluid was released in the occipital cistern in the operation group. The operation methods and routine treatment were the same in both groups. The total resection rate, , The average operating time. Results The rates of facial nerve preservation in two groups were 19 cases / 22 cases (86.40%), 22 cases / 37 cases (59.50%) (χ2 = 4.71, P < The average operative time was (2.6 ± 0.5) and (3.3 ± 0.6) and (± 0.6)% respectively in the two groups (χ2 = 4 15, P 0. 05) t = 4.60, P <0.01), with statistical significance. Conclusion Continuous drainage of the lumbar cistern in the treatment of large and medium sized acoustic neuroma microsurgical significant clinical significance, the treatment group is superior to the conventional treatment group.
