Indications and Preoperative Considerations • Meningiomas are one of the most frequently occurring intracranial primary tumors. Sphenoid wing meningiomas (SWMs) represent up to 18% of intracranial meningiomas. Those are anatomically…
Preoperative Considerations • Pituitary adenomas are benign epithelial neoplasms derived from the pituitary glands. In the absence of a macroscopic capsule, those lesions can infiltrate adjacent structures such as the…
Preoperative Considerations • Chordomas are locally aggressive neoplasms that arise from embryonic remnants of the notochord along the vertebral axis. They represent less than 1% of all intracranial neoplasms. They…
Indications and Preoperative Considerations • Postoperative CSF leak is one of the most important complications secondary to endoscopic skull base surgery. • Skull base reconstruction techniques have been instrumental for…
Introduction • Transconjunctival and endonasal approaches provide direct access to the anterior skull base and can be employed in the surgical treatment of various pathologies. • The combined transconjunctival and…
Indications • The major advantages of this approach include broad exposure to the anterior cranial base with minimal brain retraction. • The approach can facilitate the access to the anterior…
Preoperative Considerations • Craniopharyngiomas are tumors with solid-cystic components that originate from embryological remnants of the Rathke’s pouch. They represent 1–3% of lifetime intracranial tumors and up to 5–10% occurring…
• There are many surgical variants of the endoscopic endonasal approach (EEA), which can be used for management of lesions at the ventral skull base. • The main goal of…
Introduction The supraorbital approach gives access to several areas of the anterior and middle cranial fossa, sellar and parasellar region. It is a minimally invasive alternative to larger approaches such…
Preoperative Considerations • The standard retrosigmoid approach allows for expeditious access to the posterior fossa, specifically to the cerebellopontine angle (CPA). • The extended retrosigmoid approach includes the skeletonization of…
