The mesial temporal lobe can be approached via a pterional or orbitozygomatic craniotomy, the subtemporal approach, or transcortically. Alternatively, the entire mesial temporal lobe can be accessed using a lateral supracerebellar transtentorial (SCTT) approach. ⋯ The SCTT approach is especially useful for lesions in the dominant temporal lobe where an anterolateral approach may endanger language centers or the vein of Labbé.

The posterior interhemispheric approach is a versatile approach to access lesions of the pineal region, posterior incisural space, posterior region of third ventricle, and adjacent structures. We demonstrate the case of a 26-year-old woman with symptoms of increased intracranial pressure and hydrocephalus caused by a meningioma at the posteromedial tentorial incisura. ⋯ The detailed operative technique and surgical nuances, including the surgical corridor, tentorium incision, tumor dissection and removal are illustrated in this video atlas.

Tentorial dural arteriovenous fistulae (TDAVFs) are complex lesions with the arteriovenous fistula located between the leaves of the tentorium cerebelli. While a large portion of dural arteriovenous fistulae are treated endovascularly, TDAVF may require additional microsurgical treatment given their high risk of hemorrhage and multitude of feeders. We describe the case of a 65-year-old male who presented with hemorrhage from a straight sinus and galenic TDAVF. ⋯ The galenic component of the TDAVF persisted and was approached via a posterior interhemispheric approach in a lateral position. This video demonstrates surgical technique and anatomy associated with this rarely seen dural arteriovenous fistula. The video can be found here: https://youtu.be/iOLzWOabLZ0 .

OBJECT Although the length of hospital stay is often used as a measure of quality of care, data evaluating the predictors of extended hospital stay after craniotomy for tumor are limited. The goals of this study were to use multivariate regression to examine which preoperative characteristics and postoperative complications predict a prolonged hospital stay and to assess the impact of length of stay on unplanned hospital readmission. METHODS Data were extracted from the National Surgical Quality Improvement Program (NSQIP) database from 2007 to 2013. ⋯ Extended hospital stay was not associated with differential odds of an unplanned hospital readmission (OR 0.97, 95% CI 0.89%-1.06%, p = 0.55). CONCLUSIONS In this NSQIP analysis that evaluated patients who underwent craniotomy for tumor, much of the variance in hospital stay was attributable to baseline patient characteristics, suggesting length of stay may be an imperfect proxy for quality. Additionally, longer hospitalizations were not found to be associated with differential rates of unplanned readmission.
