Abstract

Retrosigmoid, subtemporal, occipital and translabyrinthine approaches can be used to reach the vestibular schwannomas. Direct approach to the CP-Angle and cerebellum with minimum retraction and the possibility of lifting the tumor away from the brainstem without causing pressure on the cerebellum and brainstem, are the most advantages of using translabyrinthine approach. If the tumor would be small, it can be removed by this approach and in case the tumor would be large, the translabyrinthine approach allows direct access to the center of the tumor and after the central debulking of the tumor, it would collapse. Complete tumor removal and facial nerve preservation can be achieved by this approach since translabyrinthine approach allows exposing the lateral end of the internal auditory meatus and finding the facial nerve while entering the fallopian canal.
