Methods The diagnoSiS and treatment of 25 patients with trigeminal schwannomas were ：analyzed retrospectively. Tumors of 5 cases in middle fossa were removed via extended transpterion approach and subtemporal- extradural approach;! Tumors of 5 cases in posterior fossa were removed via retrosigmoid approach; Dumbbel tumors of 15 Cases were removed via subtemporal transtentorial approach and transpetrous combined supra - infratentorial approach. Results Total resection was achieved in 20 of 25 cases and subtotal resection in 5 of 25 cases, There was no operative patient death. One patient had recurrence of tumor. Conclusion CT and MRI was the mainstay of the diagnosis of trigeminal schwannomas, the best treatment was complete microsurgical removal of the tumor, and suitable operative approache is the important prerequisite of treatment and prognosis,
