    Petroclival meningiomas are challenging skull base tumors due to their deep location and proximity to vital neurovascular structures.

  • 2

    The combined petrosal approach provides significant exposure for tumor resection but can be ergonomically taxing with traditional techniques.

  • 3

    Three patients underwent CPA procedures using the ORBEYE™ 4K 3D exoscope, achieving gross total resection in two cases.

  • 4

    The mean operative time for the procedures was 9 hours and 40 minutes, with one transient cranial nerve palsy and one case of pneumonia reported.

  • 5

    Initial findings suggest the 4K 3D exoscope offers excellent visualization and positive early outcomes in CPA for petroclival meningiomas.
