Complications of skull base surgery.

The increasing number of patients undergoing resection of complex skull base lesions with good outcome is indicative of the interest and expertise in treating tumors of the skull base. Advances in surgical techniques and improved knowledge of the microanatomy have contributed to the ability to manage these tumors aggressively. These procedures are not without morbidity, such as neurologic deficits, infection, and hemorrhage. These complications are expected and, with appropriate and timely management, can be minimized.
