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…
Indications and Contraindications • The addition of the orbitozygomatic (OZ) osteotomies to the fronto-temporosphenoidal craniotomy increases the surgeon’s workspace and minimizes the brain retraction required to reach deep-seated pathology. The…
Indications • Indicated for lesions located within the fourth ventricle or brainstem that extend higher than the pontomedullary junction. The alternative approach has traditionally been the transvermian approach, where the…
Indications • The pterional craniotomy and the transsylvian approach are the most used techniques in contemporary neurosurgery. • The pterional craniotomy allows exposure of the frontoparietal and temporal opercula together…
Preoperative Considerations • The transcallosal approach allows midline exposure of the anterior two-thirds of the third ventricle. • Preoperatively, in addition to standard MR imaging, venography is often helpful to…
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…
Introduction • Tumors of the lateral ventricle represent less than 1% of all intracranial tumors. The majority of these lesions are benign or low grade. • The lateral ventricles are…
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)…
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…
Indications • In general, most focal cervicomedullary tumors are considered benign in pathology. Common tumors of the cervicomedullary region include low-grade astrocytomas, gangliogliomas and ependymomas. They are typically well-delineated and…
