Abstract：
Intracanalicular vestibular schwannomas (IVS) account for 8% of all vestibular schwannomas and their detection is still increasing due to high availability of magnetic resonance (MRI). Radiosurgery is one of several commonly acceptable methods of IVS treatment, but some risk may still exist with that treatment. The aim of this study is to analyze the clinical outcomes in tumor control and hearing preservation after radiosurgery of IVS. The retrospective analysis included 14 scientific papers available in the PubMed database. Assessment of tumor volume was performed based on gadolinium-enhanced T1-weighted scans. Hearing preservation was assessed using the Gardner-Robertson classification (GR class). Statistical analysis was performed using IBM SPSS Statistics 27. It was revealed that tumor growth control in IVS treated with radiosurgery was higher than in the wait-and-see strategy. The hearing preservation was similar in patients after wait and see and the surgical group. Radiosurgery was associated with low risk of facial nerve dysfunction.
摘要：
前庭神经鞘瘤（IVS）占所有前庭神经鞘瘤的8％，并且由于磁共振（MRI）的高可用性，其检测仍在增加。放射外科是IVS治疗的几种常用方法之一，但是这种治疗可能仍然存在一些风险。这项研究的目的是分析IVS放射外科治疗后肿瘤控制和听力保护的临床结果。回顾性分析包括PubMed数据库中提供的14篇科学论文。基于钆增强的T1加权扫描进行肿瘤体积的评估。听力保护使用Gardner-Robertson分类(GR类)进行评估。使用IBMSPSSStatistics27进行统计分析。研究表明，接受放射外科治疗的IVS中的肿瘤生长控制高于观望策略。观望后的患者和手术组的听力保留相似。放射外科手术与面神经功能障碍的低风险相关。
