颅脑手术戒毒这项新的医疗技术在社会上引起很大反响，最近被卫生部紧急叫停。从颅脑手术戒毒的历史、存在的 问题、哲学及伦理方面进行反思是有必要的。把一项临床科研项目直接变换成一项临床服务项目，既未经严格科学论证也不符合伦理与法规要求。

Objective: The object of this study was to analysis the therapeu-tic effects of microsurgical excision in cases with the large or giant cerebellopontine angle meningioma. Methods: We retro-spectively analyzed the 56 patients who suffered from the large or giant cerebellopontine angle meningioma and underwent the microsurgical therapy, for which the suboccipital-retrosigmoidal approach was adopted in 38 cases, the temporal-occipital cra-niotomy, presigmoidal approach in 6 cases, the temporal-occipi-tal craniotomy, inferotemporal tentorium cerebelli approach-ing cases, and the temporal-occipital craniotomy, supratentorial or infratentorial allied approach in 4 cases. Results: The tumors of 44 cases were all resected (Simpson 1, 11), with a total resection rate of 78.6%, and there was no operative mortality. After sur-gery, symptoms improved in 40 cases and remained unchanged in 10 cases. Among 54 cases, recrudescence was seen in 2 cases (3.7%) and being able to take care of themselves in 50 cases (92.6%) at 6 months through 6 years follow-up after surgery. Conclusion: A rationally selected surgical approach, a micro-scopic technology applied in the operation to appropriately treat and protect vein, nerve and brain stem, which can ideally excise the tumors, together can increase the survival ability of patients.

目的 提高颅后窝血管网织细胞瘤的诊疗水平。方法 回顾总结31例颅后窝血管网织细胞瘤诊断方式及显微外科手术治疗效果。结果 31例肿瘤（囊性23例，实性8例），全切除30例（囊性23例，实性7例），次全切除1例（实性1例），术后神经功能明显改善27例（囊性23例，实性4例），加重3例（均为实性肿瘤），死亡1例（实性）。随访期间有3例复发（囊性1例，实性2例，其中1例实性为颈髓段再发）。结论 明确肿瘤解剖关系及血供情况，囊性肿瘤采用锁孔入路，实性肿瘤骨窗开颅，采用显微外科技术是提高疗效的重要方法。

Background: Lymphangioma of the soft tissue is not uncommon. However, as far as the authors know, intraspinal lymphangioma is clinically rare and very few cases have been reported previously. Methods: Two patients who had backache and acratia of the lower limbs and difficulty in relieving themselves were examined by plain radiography and magnetic resonance imaging before surgery. Treatment consisted of the usual technique of surgical resection of the tumor microscopically. Histological examination of the resected material confirmed the diagnosis. Postoperative follow-up assessment was performed by magnetic resonance imaging. Results: Intraspinal lymphangioma is very rare clinically and its cause remains controversial. Magnetic resonance imaging can obtain precise position fixing, but it is hard to make preoperative qualitative determination. The most effective treatment of intraspinal lymphangioma is to excise it totally. Conclusions: The clinical appearance of intraspinal lymphangioma has no character. Magnetic resonance imaging is important in diagnosing it. The most effective treatment of intraspinal lymphangioma is to excise it totally. Further observation is recommended because of the possibility of local recurrence.

目的 研究侧脑室脑膜瘤临床特点及显微外科手术治疗的效果。方法 利用CT、MRI及脑血管造影明确肿瘤的诊断，16 例侧脑室脑膜瘤均采用显微外科手术摘除。结果 本组病例肿瘤全部切除，无手术死亡。结论 CT、MRI是诊断侧脑室脑膜瘤最可靠的方法，血管造影明确肿瘤的供血情况，选择合理的手术入路应用显微外科手术可达到肿瘤的全切除。
