Exact stereotactic placement of deep brain stimulation electrodes during functional stereotactic neurosurgical procedures can be impeded by intraoperative brain shift. Brain shift has been shown to correlate with the amount of intracranial (subdural) air detected on early postoperative imaging studies. We report a simple burr hole technique that reduces the loss of cerebrospinal fluid (CSF) and has the potential to significantly reduce the amount of postoperative intracranial air. ⋯ This new and simple burr hole technique was associated with a significant reduction in postoperative intracranial air. Reduction of intracranial air will ultimately reduce brain shift. That total operation time does not influence intracranial air is discussed as well as the limitations of this pilot series. In the authors' opinion, this straightforward and cost-effective technique has the potential to reduce brain shift and to increase DBS placement accuracy during functional stereotactic neurosurgical procedures performed in the seated or half-sitting position. A larger more standardized patient series is necessary to substantiate the findings.

BACKGROUND AND STUDY OBJECT: We describe the case of a young patient treated for a ganglioglioma of the right lateral ventricle. The ganglioma was approached via a temporal route using neuronavigation. Such lesions, if confined to the ventricular system and, especially, to the lateral ventricle, are unusual. ⋯ Intraoperative MRI with DTI allows to treat such lesions via minimally invasive approaches and to reduce operative morbidity due to fiber tract damage.
