目的探讨小脑幕褶皱脑膜瘤的分型,并对预后结果进行回顾性分析研究。方法回顾性分析近11年间在我院经手术证实的起源于天幕褶皱的连续21例脑膜瘤。肿瘤最大直径1~6 cm,平均值为2.76 cm。症状包括瞳孔大小不等、复视、上睑下垂、偏盲和共济失调等。随访周期1~36个月不等。根据肿瘤生长部位,分为三种不同亚型。结果肿瘤切除程度达到SimpsonⅡ级19例,Ⅲ级1例,Ⅳ级1例。术后出现新的暂时性神经功能障碍2例,永久性神经功能障碍7例。2例神经功能障碍患者复查时得到恢复。结论小脑幕褶皱脑膜瘤术后永久性动眼神经、外展神经障碍的发生率较高,术前应予以充分考虑。并且寻找相对的平衡点,最大限度的提高患者的术后生活质量。
Objective To investigate the classification of cerebellar tentorial meningiomas and retrospectively analyze the prognosis. Methods A retrospective analysis of 21 cases of consecutive meningioma originated from canopy fold in our hospital during the past 11 years was retrospectively analyzed. The largest tumor diameter of 1 ~ 6 cm, with an average of 2.76 cm. Symptoms include pupil sizes, diplopia, ptosis, hemianopia and ataxia. The follow-up cycle ranged from 1 to 36 months. According to tumor growth sites, divided into three different subtypes. Results The tumor resection degree reached Simpson Ⅱ grade 19 cases, Ⅲ grade 1 case, Ⅳ grade 1 case. There were 2 cases of new temporary neurological dysfunction and 7 cases of permanent neurological dysfunction after operation. Two patients with neurological dysfunction recovered during the review. Conclusions The incidence of permanent oculomotor nerve and outreach neurological disorders in patients with cerebellar tentorial meningioma after operation is relatively high. Preoperative consideration should be given fully. And looking for the relative balance point, to maximize the patient’s postoperative quality of life.
