“…The systematic search yielded 31 publications. A systematic review by Alobaid et al (9) was excluded from our analysis as the four endoscopic studies included were present in our results. In the fully-ES, RS studies, the series by Shahinian and Ra (10) included cases from their institution spanning October 2001 to July 2010.…”

“…A 2015 meta-analysis by Alobaid et al (9) included 3,026 microscopic RS cases (21 series) and 790 ES cases (four series). Both fully-ES and ES-assisted cases were included; however, there appears to have been duplication of cases from two series (10,11), which has been accounted for in our current review.…”

“…For medium-sized tumors (Koos III), the reverse was true, although the numbers in this subgroup were low (three fully-ES cases, 19 ES-assisted cases). Using a GTR rate of 91% for the standard, open RS approach (9), ES-assisted surgery may be more favorable for complete resection of Koos I–II VS.…”

“…The location and integrity of nerves and vessels can be examined throughout the operation, especially when resecting large VS. Open air cells in the petrous temporal bone can be identified and sealed, potentially reducing the incidence of postoperative CSF fistulae (32). Outcomes pertaining to endoscopic skull base surgery have been demonstrated to become progressively better with length of use and expertise (9).…”

Background: Vestibular schwannomas (VS) are benign intracranial tumors originating from the vestibular division of the eighth cranial nerve. Treatment options include microsurgery, radiotherapy, and surveillance. Endoscopy is becoming more widely used as an adjunct in skull base surgery and may influence outcomes in surgically managed VS. Methods: A systematic review was conducted according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Studies involving endoscope-assisted and fully endoscopic procedures for sporadic VS resection were identified. Facial nerve function, hearing preservation, extent of resection, and complications were analyzed. Results: Thirty-one studies were included (27 endoscopeassisted, four fully endoscopic). Subgroup analyses were performed to assess outcomes according to tumor size and surgical approach. Overall, endoscopic facial nerve preservation rates were comparable to microsurgical treatment. A subgroup analysis suggested that functional facial nerve preservation rates may be higher when endoscopic assis-tance is used for smaller (Koos I-II) tumors using the retrosigmoid or translabyrinthine approach. The gross total resection rate for small tumors was higher in retrosigmoid ES-assisted microsurgery (96.2%) compared to rates in the literature for the standard, open retrosigmoid approach. Hearing outcomes were more variable and were underreported. Conclusions: Current data suggest that ES-assisted resection of sporadic VS is not inferior to microsurgical resection with respect to facial nerve outcomes and extent of resection. However, some ES series report poor hearing outcomes, which are under-reported in the literature. Further prospective studies are required to ascertain if endoscopic assistance can improve outcomes for VS resection, particularly for smaller (Koos I-II) tumors.
