Objective To investigate the clinical effect of treat severe brain trauma combine hernia with standard hemi-craniectomy and canopy incision surgery. Methods Selected 76 cases of severe brain trauma combine hernia patients as research subjects, which were randomly divided into study group and control group, 38 cases in each group, the con-trol group received standard hemicraniectomy treatment,study group received standard hemicraniectomy and atrium in-cision treatment. The clinical effects were compared for the two groups. Results The rates of severe disability or long-term coma, mortality in the study group were lower than the control group, the differences was statistically significant(P<0.05). The scores of GCS of the study group were better than the control group after operation for 4 weeks and 6 months (P<0.05). Conclusion Patients with severe brain trauma associated with hernia use standard hemicraniectomy and canopy incision treatment can effectively improve the patient's brainstem around the pool,and help to improve the survival rate of patients who received treatment.%目的：探讨对重型脑外伤合并脑疝患者经标准大骨瓣减压并天幕切开术治疗的临床疗效。方法收集76例符合研究的患者作为研究对象，随机分为研究组与对照组，均为38例。对照组给予标准大骨瓣减压方法进行治疗，研究组在对照组治疗的基础上，联合天幕切开术进行治疗，比较两组患者临床疗效。结果研究组的重残或长期昏迷率、死亡率均低于对照组，差异有显著性(P<0.05)；术后4周与6个月后，观察组的GCS评分均明显优于对照组，差异有显著性(P<0.05)。结论对重型脑外伤合并脑疝患者采取该方法进行治疗，能有效改善患者的脑干周围池，有利于提高患者治疗的生存率。
