Malignancies of the skull base represent a highly diverse and challenging set of pathologies which exhibit a wide array of oncologic behavior. In recent decades, a number of important advances in treatment technique have evolved to improve oncologic outcomes and reduce morbidity in the treatment of these aggressive cancers. Intensity modulated radiation therapy has become the gold standard in radiotherapy owing to its precision planning and reduced morbidity. However heavy ion particle radiation (proton therapy, carbon ion, etc.) are recently emerging with promising results at the skull base related to the reduced exit dose to adjacent structures. Novel systemic therapeutics such as targeted and immunotherapies may dramatically alter the treatment paradigm for many of these pathologies. Nevertheless, most skull base malignancies remain surgical diseases. The evolution of the expanded endonasal approach for a minimally invasive surgical resection has proven validity in treating many of these pathologies when properly selected, and have largely supplanted open approaches owing to the reduced morbidity profile. In spite of these important advances, the most critical aspect in comprehensive treatment is a detailed understanding of the oncologic behavior and outcomes data for each of the specific histopathologies encountered at the skull base. The nuances in management strategy, histologic profile, and surveillance planning can be stratified through the development of a comprehensive, multidisciplinary skull base team to maximize therapeutic effect and minimize morbidity for each patient. This review aims to summarize the key body of data and approaches for each of the histologies frequently encountered in the skull base, while highlighting the value and technique of endonasal approaches.
