Various embodiments of the present invention are directed to a cranial fixation device for fixing a skull flap to a skull. The cranial fixation device may be securely fastened inside a craniotomy-created perimeter burr hole so that a top surface of the cranial fixation device is flush with an outer surface of the skull and the skull flap. In one embodiment of the present invention, the cranial fixation device includes a base, a stem, and a fan washer. The base may be positioned beneath the burr hole with the interconnected stem projecting through the burr hole. The fan washer includes a fan-washer interconnection aperture and a number of peripheral fan blades. The fan washer interconnects to the stem via the fan-washer interconnection aperture and may be slid down the stem and held at a desired position within the burr hole by the peripheral fan blades.
