There are several surgical approaches for vestibular schwannoma (VS) resection. However, management has gradually shifted from microsurgical resection, toward surveillance and radiosurgery. One of the arguments against microsurgery via the middle fossa approach (MFA) is the risk of temporal lobe retraction injury or sequelae. Here, we sought to evaluate the incidence of temporal lobe retraction injury or sequela from a MFA via a systematic review of the existing literature. This systematic review was conducted according to the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) guidelines. Relevant studies reporting temporal lobe injury or sequela during MFA for VS were identified. Data was aggregated and subsequently analyzed to evaluate the incidence of temporal lobe injury. 22 studies were included for statistical analysis, encompassing 1522 patients that underwent VS resection via MFA. The overall rate of temporal lobe sequelae from this approach was 0.7%. The rate of CSF leak was 5.9%. The rate of wound infection was 0.6%. Meningitis occurred in 1.6% of patients. With the MFA, 92% of patients had good facial outcomes, and 54.9% had hearing preservation. Our series and literature review support that temporal lobe retraction injury or sequelae is an infrequent complication from an MFA for intracanalicular VS resection.
有几种手术方法可用于切除前庭神经鞘瘤(VS)。然而,治疗策略已逐渐从显微切除术转变为观察和放射外科治疗。经中颅窝入路(MFA)行显微切除术的一个弊端是存在颞叶牵拉损伤或后遗症的风险。在此,我们通过对现有文献的系统回顾,旨在评估 MFA 所致颞叶牵拉损伤或后遗症的发生率。本系统评价按照系统评价和荟萃分析的首选报告项目(PRISMA)指南进行。确定了报告在 MFA 治疗 VS 期间出现颞叶损伤或后遗症的相关研究。汇总数据并进行分析,以评估颞叶损伤的发生率。有 22 项研究被纳入统计学分析,共纳入 1522 例经 MFA 行 VS 切除术的患者。该入路术后出现颞叶后遗症的总体发生率为 0.7%。CSF 漏的发生率为 5.9%。伤口感染的发生率为 0.6%。脑膜炎的发生率为 1.6%。采用 MFA 后,92%的患者面部功能良好,54.9%的患者听力得到保留。我们的系列研究和文献复习支持,对于经 MFA 切除内听道 VS,颞叶牵拉损伤或后遗症是一种罕见的并发症。
