目的探讨枕下经天幕入路显微手术切除幕下型天幕脑膜瘤的可行性及治疗效果。方法回顾性分析枕下经天幕入路显微手术切除幕下型天幕脑膜瘤12例的临床资料,采用枕部近中线骨瓣开颅,在手术显微镜下操作,切开天幕用显微技术切除肿瘤。结果临床应用12例,除1例因肿瘤向窦内生长有少量残留外,其余各例都获得肿瘤全切除,术后全部病例的临床症状明显改善,无脑神经损伤,无死亡及严重并发症发生。结论枕下经天幕入路是切除幕下型天幕脑膜瘤比较安全可靠的方法,用显微技术可提高手术的临床效果。
Objective To investigate the feasibility and therapeutic effect of microsurgical removal of infratentorial meningiomas by suboccipital approach. Methods The clinical data of 12 cases undergoing subacute subepithelial meningioma by microsurgery under the canopy were retrospectively analyzed. The craniotomy was performed with the craniotomy near the midline of the occipital lobe and under the operating microscope. The tumor was excised by microsurgical technique . Results The clinical application of 12 cases, except for a case of tumor growth to the sinus a small amount of residual, the remaining cases were all tumor resection, all cases of clinical symptoms improved significantly, no cranial nerve injury, no death and serious complications occur. Conclusions The transtibial transtibial approach is a safe and reliable method for the removal of the infratentorial meningioma. Using microscopic techniques can improve the clinical effect of the operation.
