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…
Preoperative Considerations • The far lateral provides wide access to the dorsolateral compartment yet allowing exposure to the lateral aspect of the ventromedial compartment of the posterior fossa (270° visualization…
There are a variety of different techniques that can be used to surgically manage anterior skull base lesions. In this chapter we demonstrate the value of the standard and extended…
Preoperative Considerations • Pituitary adenomas are the most prevalent intrasellar lesions and the third most prevalent primary intracranial tumors. These lesions can lead to significant neurologic and/or endocrine-related morbidity secondary…
Preoperative Considerations • Microscopic transcortical or transcallosal approaches may be associated with brain injury and/or retraction that can result in seizures, focal neurologic deficits and cognitive impairment. Endoscopic approaches for…
