    The carotid distal dural ring (DDR) is a critical structure formed by the dura mater around the internal carotid artery (ICA) at the skull base.

  • 2

    Meticulous dissection is essential during skull base surgeries to prevent complications like ICA injury, optic nerve damage, and CSF leaks.

  • 3

    The surgical technique involves a stepwise approach, including a frontotemporal craniotomy and anterior clinoidectomy to access the DDR.

  • 4

    Dural incisions are made carefully to minimize trauma, allowing for exposure of the ICA and the neck of any aneurysms present.

    Hemostasis in the cavernous sinus can be achieved using fibrin glue or hemostatic sponges to manage minor bleeding during the procedure.
