    The exo- and endoscopic two-step approach (EETA) enhances visualization and resection of recurrent vestibular schwannomas post-surgery and radiosurgery.

  • 2

    The retrosigmoid approach (RSA) allows access to the cerebellopontine angle but has limitations in visualizing the fundus of the internal auditory canal.

  • 3

    Step 1 of EETA involves removing the extracanalicular component using an exoscope, facilitating precise dissection despite previous adhesions.

  • 4

    Step 2 utilizes rigid endoscopes to examine the internal auditory canal and excise residual intracanalicular components, minimizing tumor recurrence.

  • 5

    Two case studies demonstrate the effectiveness of EETA in managing recurrent vestibular schwannomas, with patients experiencing no complications post-surgery.
