Resumen
The technical development in skull base surgery, especially to the anterior cranial fossa, has allowed for improvement in the quality of life and the long-term prognosis of patients suffering from different types of tumors that can affect this anatomical area. Applying these advanced techniques requires a thorough understanding of the skull base anatomy and surrounding structures to perform surgery without potential intraoperative complications related to the pathology itself as well as potential complications related to the surgical approach that has been chosen to treat this pathology. The purpose of this paper is to offer a comprehensive review of the surgical anatomy of the anterior skull base and the technical nuances of the surgical approaches that are more frequently used in this region.
