Indications Frontotemporal craniotomy with orbitozygomatic osteotomy is an adjunct to pterional craniotomy that allows greater rostral trajectory to midline structures. By removing the superior and lateral bony orbit, one gains a more anterior and inferior starting point for the approach…
Indications Supraorbital craniotomy allows for relatively easy and rapid access to structures in the anterior, middle cranial fossa and sellar and parasellar regions. This minimally invasive technique provides a subfrontal approach with minimal disruption of normal anatomy, excellent cosmetic results,…
Indications Parasagittal approaches are used to treat lesions located near the falx, interhemispheric fissure, or corpus callosum. These lesions often include parasagittal and falcine meningiomas, intraaxial tumors, cavernomas, and arteriovenous malformations (AVMs). The parasagittal approach is also the first step…
Indications Elevated intracranial pressure (ICP) is one of the most common causes of death and disability following severe traumatic brain injury and ischemic stroke. There have been no new medical treatments for elevated ICP in more than 90 years. A…
Indications An occipital transtentorial craniotomy can provide excellent exposure for falcotentorial meningiomas and any lesion arising from the precentral cerebellar fissure, posterior incisural space, and adjoining structures. Contraindications Standard medical contraindications for prone positioning. Patent foramen ovale with positive bubble…
Indications This approach provides optimal exposure for lesions in the pineal region, posterior third ventricle, and posterior mesencephalon with minimal to no damage to the healthy parenchyma and surrounding structures. You’re Reading a Preview Become a Clinical Tree membership for…
Indications The expanded endonasal transsphenoidal approach is employed for various pathologies involving the sella, suprasellar space, and sphenoid bone, including pituitary adenomas, Rathke pouch cyst, and craniopharyngiomas. Other indications include clival chordomas, meningiomas, metastatic lesions, and medial temporal lobe lesions…
Indications Tumors of the lateral and anterior third ventricles. Contraindications The transcallosal approach, although it provides exposure to tumors in the lateral and anterior third ventricle, is limited in providing satisfactory access to tumors in the posterior trigone, temporal horn,…
There are multiple variations of the presigmoid approach to the posterior fossa: retrolabyrinthine, transcrusal, translabyrinthine, transotic, and transcochlear. Each variation increases the amount of temporal bone resected, which increases the surgical freedom at the expense of increased surgical morbidity of…
Indications Lesions in the cerebellopontine angle and petroclival region can be surgically challenging to resect because of surrounding vascular and eloquent neural structures (i.e., brainstem) that have zero tolerance for retraction. Numerous surgical approaches, such as translabyrinthine, transcochlear, and presigmoid…
