ABSTRACT
Skull base tumors are those that penetrate completely through the bone at the base of the skull. By definition, dura is invaded or, at the very least, exposed. The classification of the skull base into three zones is helpful in determining the surgical approach, selecting the method of reconstruction, and comparing clinical outcomes following extirpation of tumors. The principle of reconstruction is to separate exposed dura-or dural repair-from the pharynx, paranasal sinuses, and external environment; to protect vital structures; and to eliminate dead space by vascularized tissue. Free tissue transfer has decreased the complication rate and permitted much more aggressive resection, improving the prognosis for these patients.
