The authors present an overview on CT-guided stereotaxy performed in the last 10 years in the University Hospital Olomouc. During this period a total of 811 stereotactic brain operations were performed. Of these, 710 were done in the field of afunctional and 101 in the field of functional stereotaxy. The majority of procedures were biopsies of intracranial lesions (n = 464), evacuations of intr...

BACKGROUND Stereotactic biopsy for brainstem lesion offers high diagnostic yield with low morbidity. We compared two modalities of biopsy procedure, frame-based and frameless stereotaxy, either transfrontal or transcerebellar route. The benefits and operation considerations are discussed. METHODS Ten patients with intrinsic brainstem lesion diagnosed with stereotactic biopsy from August 2006 ...

Background Robot-assisted stereotaxy (RAS) promises higher stereotactic accuracy (SA) and time efficiency (TE) than frame-based stereotaxy. However, both aspects are attributed to the problem of patient-to-robot registration. Objective To examine different registration techniques regarding their SA TE. Methods This study enrolled 57 patients undergoing RAS with bone fiducial (BFR) or laser surf...

The first goal in neurosurgery is to protect neural function as long as it is possible. Moreover, while protecting the neural function, a neurosurgeon should extract the maximum amount of tumoral tissue from the tumour region of the brain. So neurosurgery and technological advancement go hand in hand to realize this goal. Using of CT compatible stereotaxy for removing a cranial tumour is to be ...

this study was conducted to find out the best outside points of skull to reach different areas of brain thatare essential for neuroendocrinological studies. in this research 30 heads of iranian native male goats agedbetween 2-3-year-old were collected from shahrekord abattoir. after collecting whole heads, they were fixedin 10% formalin and then many holes were made on the dorsal surface of sku...

Today's neurosurgical journals are replete with advertisements for systems designed to provide image guidance during surgery. These so-called "frameless" stereotactic systems provide the surgeon with navigational information, relating the location of instruments in the operative field to preoperative imaging data. Such information minimizes invasiveness by more accurately selecting the best tra...
