Neuronavigation in Skull Base Tumors

Minimally Invasive Neurosurgery, 2005
Computer-assisted neuronavigation was used in 87 cases of skull base lesions (SBLs). Preoperative planning and intraoperative identification of anatomic landmarks is especially important in SBLs since it helps to avoid or minimize surgical morbidity and mortality. In this study, we assessed the accuracy and the clinical usefulness of a frameless system

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 ...

Neuroendoscopy combined with frameless neuronavigation

British Journal of Neurosurgery, 2000
Minimal invasive neurosurgery is becoming more and more standard in neurosurgical procedures. Several types of lesions are now approached endoscopically. The surgical planning and intraoperative orientation during endoscopic surgical procedures are sometimes difficult.

Use of Neuronavigation in Suturectomy for Craniosynostosis

Journal of Craniofacial Surgery, 2023
Smaller operative exposures associated with suturectomy for craniosynostosis may result in difficulties visualizing the prematurely fused suture during surgery. The authors report cases of suturectomy for lambdoid and metopic craniosynostosis in which neuronavigation or frameless stereotaxy was used to assist with incision planning and intraoperative ...

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 ...

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.

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.
