前床突脑膜瘤术后视力的影响因素研究

Study on the factors influencing postoperative visual acuity of anterior clinoid meningioma

目的探讨前床突脑膜瘤(ACMs)术后视力恢复的影响因素。方法回顾性分析自1999年7月至2021年6月由笔者行手术治疗的63例ACMs患者的临床资料,包括视觉功能和影像学特点、手术记录以及术后视觉随访结果,评估肿瘤的切除程度,分析影响患者术后视觉功能的因素。结果本组患者中Simpson I~Ⅱ级全切除48例(76.2%),Simpson Ⅲ~Ⅳ切除15例(23.8%);术后视力总体改善率、稳定率和恶化率分别为76.2%(48/63)、15.9%(10/63)、7.9%(5/63)。术后永久性并发症4例,其中视力恶化2例,新发偏瘫1例,部分性动眼神经麻痹1例。无死亡病例。单因素分析结果表明,术前视力水平、肿瘤分型、术中是否开放视神经管是术后视觉功能的影响因素(P<0.05)。结论术前评估视力水平、肿瘤类型有助于预测ACMs患者术后的视觉功能水平,术中恰当选择开放视神经管的适应证有助于提高术后视力改善率。

Objective To investigate the influencing factors of visual acuity recovery after anterior clinoid meningiomas (ACMs) surgery.Methods The clinical data of 63 patients with ACMs who were operated on by the authors from July 1999 to June 2021 were analyzed retrospectively, including visual function and imaging characteristics, surgical records and postoperative visual follow-up results. The degree of tumor resection was evaluated, and the factors affecting the postoperative visual function were analyzed.Results In this group, 48 patients (76.2%) underwent Simpson Ⅰ-Ⅱ total resection, and 15 patients (23.8%) underwent Simpson Ⅲ-Ⅳ resection. The overall improvement rate, stability rate and deterioration rate of postoperative visual acuity were 76.2% (48/63), 15.9% (10/63) and 7.9% (5/63), respectively. The results of univariate analysis showed that preoperative visual acuity, tumor classification and whether the optic canal was opened during operation were the influencing factors of postoperative visual function (P<0.05). Postoperative permanent complications occurred in 4 cases, including 2 cases of vision deterioration, 1 case of new hemiplegia and 1 case of partial oculomotor nerve palsy. There were no deaths.Conclusion Preoperative evaluation of visual acuity and tumor type is helpful to predict the postoperative visual function level of ACMs patients. Proper selection of indications for opening the optic canal during operation is helpful to improve the postoperative visual acuity.
