PURPOSE To investigate the value of intraoperative MR imaging (iopMRI) combined with neuronavigation to avoid intraoperative underestimation of the resection amount during surgery of lesional temporal lobe epilepsy (LTLE) patients. METHODS We retrospectively investigated 88 patients (40 female, 48 male, mean age 37.2 yrs, from 12 to 69 yrs, 41 left sided lesions) with LTLE operated at our dep...

BACKGROUND Awake craniotomy is currently the gold standard for aggressive tumor resections in eloquent cortex. However, a significant subset of patients is unable to tolerate this procedure, particularly the very young or old or those with psychiatric comorbidities, cardiopulmonary comorbidities, or obesity, among other conditions. In these cases, typical alternative procedures include biopsy a...

Image guidance in pituitary surgery has evolved since diagnostic imaging of the sellar region was first introduced at the turn of the 20th century. These advances have played a key role in the decrease in morbidity and mortality once associated with pituitary surgery. This chapter details the history of sellar imaging as a preoperative diagnostic aide, and then examines the subsequent developme...

Brain shift, i. e. the change in configuration of the brain after opening the dura mater, is a key problem in neuronavigation. We present an approach to co-register intra-operative microscope images with preoperative MRI data to adapt and optimize intra-operative neuronavigation. The tools are a robust classification of sulci on MRI extracted cortical surfaces, guided user marking of most promi...

In the past two decades, endoscopic sinus surgeries (ESS) have been widely advocated as a safe and effective treatment for disorders of paranasal sinuses that are refractory to medical therapy. ESS caters surgeons with two-dimensional visualization of the anatomical structures; however in scenarios where there is a close anatomical relation between the disease and delicate intracranial or intra...
