BackgroundVestibular schwannomas (VS) are uncommon lesions that are a substantial challenge to the neurosurgeons, otologists, and radiation oncologists who undertake their clinical management. A starting point to improving the current knowledge is to define the benchmarks of the current research studying VS management using evidence-based techniques in order to allow meaningful points of departure for future scientific and clinical research.ObjectiveTo establish the best evidence-based management of VS, including initial otologic evaluation, imaging diagnosis, use of surgical techniques, assessment of tumor pathology, and the administration of radiation therapy.MethodsMultidisciplinary writing groups were identified to design questions, literature searches, and collection and classification of relevant findings. This information was then translated to recommendations based on the strength of the available literature.ResultsThis guideline series yielded some level 2 recommendations and a greater number of level 3 recommendations directed at the management of VS. Importantly, in some cases, a number of well-designed questions and subsequent searches did not yield information that allowed creation of a meaningful and justifiable recommendation.ConclusionThis series of guidelines was constructed to assess the most current and clinically relevant evidence for the management of VS. They set a benchmark regarding the current evidence base for this type of tumor while also highlighting important key areas for future basic and clinical research, particularly on those topics for which no recommendations could be formulated.  The full guidelines can be found at: https://www.cns.org/guidelines/guidelines-management-patients-vestibular-schwannoma.Copyright © 2017 by the Congress of Neurological Surgeons
