“…From our experience with the cases reported here, it has a precision between 1 and 3 mm. These findings are confirmed by other authors using the same 11,15,19 and similar systems. 3,[5][6][7]16 From the surgical point of view, intraoperative navigation can provide vital information about the anatomical situation during surgery.…”

“…In 15 maxillofacial surgery cases, Hassfeld et al found an accuracy better than 3 mm using the SPOCS system. 11 Schaller et al used the SPOCS System in 33 neurosurgery patients and found an accuracy in the range of 3 mm or better, 15 and Wirtz et al found an RMSE of 3.3 Ϯ 0.9 mm in 15 cases. 19 From the technical point of view, the CCD camera has a very high spatial resolution of Ͻ1mm.…”

Five patients with chronic sinus pathology and an indication for sinus surgery were selected. For intraoperative navigation, we used Surgical Planning and Orientation Computer Systems (SPOCS) Aesculap navigation software (ISG Technologies, Mississauga, Ontario, Canada) and surgical instruments fitted with light-emitting diodes. Navigation procedures are described in detail in the article. The system's precision was measured by pointing at anatomical landmarks. The accuracy was measured as the distance in millimeters between the bony structures of the computed tomographic (CT) scan on screen and the cross-hair of the pointer tip displayed on the screen. Another parameter of the system's accuracy was calculated by the system itself as the root mean square error in millimeters between the markers' position as registered and their position in the CT data set. Axial 3/3/1-mm spiral CT provided sufficient resolution, and data transfer via optical disk was practicable. Positioning of the navigation equipment required some experience, and the registration of the patient's head position also needed attention, as the markers have to be pointed at precisely. During the operation, the position of the head-tracking system on the patient's head must remain unchanged to ensure a correct navigation display. The main advantage of the computed navigation system was the constant orientation provided during the sinus surgical procedure. Borders and critical anatomical structures could be identified in the corresponding CT data set, thus enabling the surgeon to decide on subsequent procedures. Use of the navigation system was found to increase the operation time by about 1 h, resulting in additional time under anesthesia. We found the SPOCS Aesculap computed navigation system to be an established technical aid, ready for use in ENT sinus surgery. In the cases reported here, a precision between 1 and 3 mm was obtained.

“…First, in contrast to other common navigation procedures (eg, in surgery close to the base of the skull or in bone surgery [8][9][10][11][12][13][14][15][16][17][18][19][20][21] ), it is not necessary to attach a fixed reference rigid body to the patient's body. The function of such a reference rigid body, which must be attached in direct proximity to the operating site, is to guarantee reliable navigation even when either the pointing device or the location of the object is altered.…”

“…The interaction of sophisticated surgical microscopes and neuronavigational systems brings the principles of robotics to the image-guided resection of tumours. The procedures can be performed under general anaesthesia or in a scalp block as in awake surgeries [106][107][108][109][110][111]. The type of neurosurgical procedure depends on many factors, such as the location and size of the tumour, its vascularity and composition, the diversity of tumours (solitary, multiple metastases, or involvement of many lobes), accessibility, eloquent areas of the brain, the clinical condition and wishes of the patient, and yet the surgical equipment [106].…”

Neurosurgical Approaches to Brain Tissue Harvesting for the Establishment of Cell Cultures in Neural Experimental Cell Models

In recent decades, cell biology has made rapid progress. Cell isolation and cultivation techniques, supported by modern laboratory procedures and experimental capabilities, provide a wide range of opportunities for in vitro research to study physiological and pathophysiological processes in health and disease. They can also be used very efficiently for the analysis of biomaterials. Before a new biomaterial is ready for implantation into tissues and widespread use in clinical practice, it must be extensively tested. Experimental cell models, which are a suitable testing ground and the first line of empirical exploration of new biomaterials, must contain suitable cells that form the basis of biomaterial testing. To isolate a stable and suitable cell culture, many steps are required. The first and one of the most important steps is the collection of donor tissue, usually during a surgical procedure. Thus, the collection is the foundation for the success of cell isolation. This article explains the sources and neurosurgical procedures for obtaining brain tissue samples for cell isolation techniques, which are essential for biomaterial testing procedures.
