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 cavernous and sphenoid sinuses, dura and brain parenchyma. These tumors are…
Indications and Preoperative Considerations Meningiomas represent 34% of all primary brain tumors, originate from the arachnoid cells in the brain and spine and are histologically non-cancerous lesions. Anterior midline meningiomas can be classified according to their location ( Figure 31.1…
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 the development of endoscopic skull base surgery. Continuous research has been done…
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 during childhood. They are commonly located in the suprasellar region, arising…
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 to compression of neurovascular structures and hormonal dysfunction. Pituitary adenomas may…
Indications and Preoperative Considerations Posterior fossa meningiomas are uncommon lesions that can be found virtually anywhere in the infratentorial space. The management of these lesions will depend on their size, location, growth rate and clinical presentation. These tumors can be…
Indications and Preoperative Considerations Falcine meningiomas are extradural lesions that arise from the falx cerebri. They might be classified based on their relationship with the superior sagittal sinus (SSS) into anterior, middle or posterior lesions, each requiring different techniques for…
Indications and Preoperative Considerations Meningiomas are one of the most common primary intracranial brain tumors. They represent 34% of all primary brain tumors and originate from the arachnoid cells in the brain and spine. The brain convexity is the most…
