| Research Abstract |
The development of image-guided systems rendered it possible to perform frameless stereotactic surgery for deep brain stimulation (DBS). As well as stereotactic targeting, neurophysiological identification of the target is important. Multi-tract microrecording is an effective technique to identify the best placement of an electrode. This is a report of our experience of using the Nexframe frameless stereotaxy with Ben's Gun multi-tract microrecording drive, and we study the accuracy, usefulness and disadvantages of the system. As a result, the accuracy of this system is similar to that of frame-based stereotaxy. However, the narrow surgical field is a disadvantage for multiple electrodes insertion. Thus far, we do not consider that this technology in its present state can replace conventional frame-based stereotactic surgery.
