Endoscopic Endonasal Skull Base Tumor Resection

Endoscopic transnasal resection can be considered when the lesion is located in the midline or close to the nasal-sphenoid sinus passage, the imaging evaluation shows that it is reachable, and the boundary with important structures is acceptable. The decision is affected by the type and extent of the tumor, whether it involves cranial nerves/major blood vessels, previous surgery or radiotherapy history, endocrine and overall condition, and requires appropriate skull base reconstruction conditions, which are determined by multidisciplinary evaluation.
