Comparison of In-Hospital Costs for Expanded Endonasal Approaches and Craniotomy for Anterior Skull Base Tumors

Introduction: Meningiomas and craniopharyngiomas are benign anterior skull base tumors frequently encountered by skull base surgery teams. Each tumor has been historically approached surgically via an open transcranial route, but an expanded endonasal approach (EEA) has been increasingly utilized over recent years. In our study, we seek to quantify the in-hospital costs associated with an EEA relative to the open approach for both pathologies.
