Background: Neuronavigation helps neurosurgeons by providing intraoperative three dimensional (3D) view of CT/MRI of the patients thus helping the surgeon in different steps of surgery. With the objective to evaluate the usefulness of neuronavigation in early years after installment, this study was conducted at a tertiary care center in Nepal. Methodology: This is a prospective analytical study, where all the consecutive cases of the neurosurgical cranial cases using frameless stereotactic (Medtronics stealth station 7), were considered during May 2014 to March 2017. All the lesions were categorized according to the location and were evaluated using the Image guided surgery (IGS) score. Analysis was done using stratification and percentage system. Result: There were total 122 cases operated using neuronavigation during the study period, with ages ranged between 5 to 83 years with mean age 38.32(SD16.09) years. 57.4% were male and 42.6% were female. Overall IGS scoring of the neuronavigation in the different location showed irreplaceability in 100% cases of convexity, ganglionic/ deep seated/ ventricle and brain stem lesion; however, it was more useful than conventional methods in 70.37% of lobar cases. Similarly, overall IGS scoring of neuronavigation in the different type of lesions showed irreplaceable in 80% of meningiomas, and 41.17% of gliomas; however, was more useful than conventional methods in 56.86% of gliomas Conclusion:Use of neuronavigation seems to be irreplaceable for planning and raising flaps, in cases of convexity lesions and most of the cases of lobar and ganglionic/ deep seated leasions.

Invasive Method

The advent of modern image-guided surgery has revolutionized depth electrode implantation techniques. Stereoelectroencephalography (SEEG), introduced by Talairach in the 1950s, is an invasive method for three-dimensional analysis on the epileptogenic zone based on the technique of intracranial implantation of depth electrodes. The aim of this article is to discuss the principles of SEEG and their evolution from the Talairach era to the image-guided surgery of today, along with future prospects. Although the general principles of SEEG have remained intact over the years, the implantation of depth electrodes, i.e. the surgical technique that enables this method, has undergone tremendous evolution over the last three decades, due the advent of modern imaging techniques, computer systems and new stereotactic techniques. The use of robotic systems, the constant evolution of imaging and computing techniques and the use of depth electrodes together with microdialysis probes will open up enormous prospects for applying depth electrodes and SEEG both for investigative use and for therapeutic use. Brain stimulation of deep targets and the construction of "smart" electrodes may, in the near future, increase the need to use this method.

AbstractAugmented reality (AR) superimposes computer-generated virtual objects onto the user’s view of the real world. Among medical disciplines, neurosurgery has long been at the forefront of image-guided surgery, and it continues to push the frontiers of AR technology in the operating room. In this systematic review, we explore the history of AR in neurosurgery and examine the literature on current neurosurgical applications of AR. Significant challenges to surgical AR exist, including compounded sources of registration error, impaired depth perception, visual and tactile temporal asynchrony, and operator inattentional blindness. Nevertheless, the ability to accurately display multiple three-dimensional datasets congruently over the area where they are most useful, coupled with future advances in imaging, registration, display technology, and robotic actuation, portend a promising role for AR in the neurosurgical operating room.
