Neuronavigation-assisted Cranial Reconstruction

Neurosurgery, 2004
Cranial defects resulting from congenital deformities, ablative resection of osseous tumors, traumatic injury, and destructive infectious lesions are often severe enough to warrant surgical reconstruction. In particular cases, satisfactory cosmetic results may be difficult to achieve because of the extent and location of the lesion.We evaluated the ...

Clinical Experiences in Neuronavigation

Stereotactic and Functional Neurosurgery, 2001
We have successfully used a navigation system in more than 120 neurosurgical operations for past two years. The neuronavigation system provides high levels of mechanical accuracy in surgical localization, especially for small deep-seated masses or epileptic foci, surgical planning for intrinsic and extrinsic brain tumors, and arteriovenous malformation

Frameless Neuronavigation in Modern Neurosurgery

min - Minimally Invasive Neurosurgery, 1995
A fundamental effort in neurosurgery is to reduce surgical trauma. Microneurosurgical technique combined with precise localization of lesions, can minimize the invasiveness of neurosurgical procedures. This report summarizes the utility of frameless neuronavigator systems and examines their value in reducing operative invasiveness.

First neuronavigation experiences in Uruguay

2010 Annual International Conference of the IEEE Engineering in Medicine and Biology, 2010
Neuronavigation is the application of image guidance to neurosurgery where the position of a surgical tool can be displayed on a preoperative image. Although this technique has been used worldwide in the last ten years, it was never applied in Uruguay due to its cost.

Neuronavigation and surgery of intracerebral tumours

Journal of Neurology, 2006
Approximately four decades after the successful clinical introduction of framebased stereotactic neurosurgery by Spiegel and Wycis, frameless stereotaxy emerged to enable more elaborate image guidance in open neurosurgical procedures. Frameless stereotaxy, or neuronavigation, relies on one of several different localizing techniques to determine the ...

Neuronavigation – Impact on Operating Time

Stereotactic and Functional Neurosurgery, 1998
It is uncertain whether the use of imaggguided surgery has an influence on operating time. We prospectively studied the time requirements which have to be invested for using image-guided surgery and performed a comparison of operating room times from 125 matched pairs of image-guided and conventional operations.

The impact of auditive feedback on neuronavigation

International Congress Series, 2003
Abstract To improve the usefulness of the information offered by neuronavigation systems, we developed an auditive feedback system which can be used in addition to regular neuronavigation. Using a serial connection, instrument coordinates determined by a commercially available neuronavigation system were transferred to a laptop computer.

Error Analysis in Cranial Neuronavigation

min - Minimally Invasive Neurosurgery, 2002
Neuronavigation systems are now an important component of many modern neurosurgical treatment strategies. Their support facilities intraoperative orientation and makes neurosurgical operations more precise and less traumatic. Computer-aided neurosurgery is definitively not a temporary fashionable phenomenon, the concept of neuronavigation is here to ...

Neuronavigation and Neuroendoscopy

1998
In neuroendoscopy orientation and localisation of the endoscope’s tip is crucial. Additionally the endoscopic view can be obscured by solid structures or membranes.

Practicability of magnetoencephalography-guided neuronavigation

Neurosurgical Review, 2002
Magnetoencephalography (MEG) is a noninvasive option for localizing electroneurophysiological activity on the human cortex. The purpose of this study was to evaluate the practicability and reliability of MEG imaging integrated into a neuronavigation system to identify the sensorimotor cortex intraoperatively in patients with brain tumors in or near the
