The surgical corridors for MVD for trigeminal neuralgia (supralateral cerebellar approach-blue arrow) as well as hemifacial spasm, and glossopharyngeal neuralgia (infralateral cerebellar or infrafloccular approach-green arrow) are illustrated.

During awake language mapping for posteroinferior temporal lobe gliomas, once tumor resection begins, language exams are performed continuously to avoid inadvertent tract injury, and a 1cm safety margin is respected around functional tissue.

Diagramed here are some of the various craniotomy approaches which can be used to access lesions of the brainstem. The telovelar, retrosigmoid, and paramedian supracerebellar are among the most favorable approaches for many of these lesions.

During insular tumor resection, once the perforating arteries have been coagulated and divided, several pial incisions can be made on the insular cortex between the M2 branches.

During insular tumor resection, the M2 perforators on the insular cortex must be thoroughly coagulated and sharply cut to avoid injury to the parent vessel via their avulsion. For more, be sure to check out the following link: https://t.co/WqpYe5I1eh

During resection for low-grade gliomas, the tumor is finally disconnected at the depth of the cavity and removed. Navigation is then used to estimate the extent of resection.

During resection for low-grade gliomas, initial subpial coagulation marks the superficial tumor edges and devascularizes the surface of the tumor.

During radiofrequency rhizotomy, electrode depth determines which divisions of the trigeminal nerve will be contacted. V3 is contacted if the electrode is 5mm proximal to the clivus, V2 at the clivus, and V1 when the electrode is 5mm distal to the clivus.

Illustrated here is the general architecture of a convexity AVM, showing large feeding arteries hiding within the peri-AVM sulci. Primary draining veins can wrap around deeper parenchymal portions of the AVM and should be protected during disconnection.
