Abstract

The study of the proximal distal dural ring has been of interest to skull base surgeons for many years. Numerous reports attempt to characterize these structures and to relate them to the surrounding anatomy. The evolution of skull base surgery, which includes less invasive techniques to treat aneurysms or radiosurgery for skull base tumors, applies even greater pressure for skull base surgeons to minimize the complications associated with surgery. This outstanding anatomical study by Beretta and coworkers helps skull base surgeons to fulfill this challenging obligation.
