目的 探讨应用接触式激光显微手术治疗颅底脑膜瘤的治疗效果。方法 应用接触式激光显微手术治疗颅底脑膜瘤 2 0例 ,与传统显微手术方法治疗颅底脑膜瘤 2 6例进行临床效果分析。结果 激光组 17例全切 ,2例近全切 ,1例大部分切除 ,术中平均输血 810ml;而对照组 15例全切 ,7例近全切 ,4例大部分切除 ,平均输血 10 70ml,P <0 0 5。前者无 1例病情加重或死亡 ,随访半年至 2年 ,1例岩 -斜坡脑膜瘤术后 1年复发 ;后者术后症状改善 12例 ,加重 3例 ,死亡 2例 ,随访期同上 ,有3例 1年后肿瘤复发。结论 接触式激光适用于供血丰富的肿瘤切除 ,对颅底脑膜瘤等脑深部肿瘤手术切除 ,能减少术中出血和对周围组织的损害 ,避免术后并发症发生 ,降低死亡率 ,提高颅底脑膜瘤的全切除率。
Objective To investigate the therapeutic effect of contact laser microsurgery for skull base meningioma. Methods Twenty patients with skull base meningiomas were treated with contact laser microsurgery and 26 patients with skull base meningiomas were treated with traditional microsurgery. Results In the laser group, 17 cases were completely excised, 2 cases were subtotalized and 1 case was resected. The average blood transfusion was 810ml in the laser group. In the control group, 15 cases were completely excised, 7 cases were subtotally resected and 4 cases were mostly resected. , P <0 0 5. None of the former patients had exacerbations or deaths. One year after operation, one case of rock-slope meningioma recurred after one year of operation. The latter had 12 cases of postoperative improvement, 3 cases of aggravating, and 2 deaths. The follow-up period was the same as the above Three cases of tumor recurrence after 1 year. Conclusions Contact laser is suitable for excision of tumors with rich blood supply. Surgical resection of deep brain tumors such as skull base meningiomas can reduce intraoperative bleeding and damage to surrounding tissues, prevent postoperative complications, reduce mortality and increase skull base Meningioma total resection rate.
