This is a heterogenous group which requires detailed investigation and careful consideration to management strategy. The optimal management for these tumours remains unclear and there are several controversies. The aim of this paper is to provide insight into the main principles defning management and surgical strategy, in order to formulate a series of recommendations. Methods A task force was created by the EANS skull base section committee along with its members and other renowned experts in the feld to generate recommendations for the surgical management of these tumours on a European perspective. To achieve this, the task force performed an extensive systematic review in this feld and had discussions within the group. This article is the second of a three-part series describing non-vestibular schwannomas (V, VII). Results A summary of literature evidence was proposed after discussion within the EANS skull base section. The constituted task force dealt with the practice patterns that exist with respect to pre-operative radiological investigations, ophthalmologi- cal assessments, optimal surgical and radiotherapy strategies, and follow-up management. Conclusion This article represents the consensually derived opinion of the task force with respect to the treatment of trigeminal and facial schwannoma. The aim of treatment is maximal safe resection with preservation of function. Careful thought is required to select the appropriate surgical approach. Most middle fossa trigeminal schwannoma tumours can be safely accessed by a subtemporal extradural middle fossa approach. The treatment of facial nerve schwannoma remains controversial. Keywords Non-vestibular schwannoma · Radiosurgery · Trigeminal schwannoma · Facial nerve schwannoma · Quality of life Introduction The description of a schwannoma was frst by Verocay in 1910 [34, 80]. These tumours originate from Schwann cells, with the majority arising from the cranial nerves. Predomi- nately tumours originate on the sensory nerves, but there is an association with tumours that arise from motor nerves with neurofbromatosis (NF) [70, 72]. For the non-vestibular schwannoma cohort, trigeminal schwannomas are the most common representing between 0.8 and 8% of schwannomas [38], followed by jugular This article is part of the Topical Collection on Tumor— Schwannoma * Dimitrios Paraskevopoulos d.paraskevopoulos@nhs.net Extended author information available on the last page of the article
