Neurosurgery o/the Future: Computers and Robots in Clinical Neurosurgical Practice and in Training - a Philosophical Journey into the Future Many present day neurosurgeons believe that they already obtain good results in operative surgery with the benefit of the operating microscope and other aids which have become available in the last three decades and that the introduction of computers and robots to the operating theatre is superfluous. However, it is clear from analogy with the function of the airline pilot, another profession where there are great demands on manual skill and on spatial awareness, that these devices do have much to offer neurosurgery. Classical neurosurgery, in the time of Cushing, Dandy and Scarff, was based on a three dimensional picture of the patient's brain formed in the surgeon's mind and often illustrated in elegant drawings. Such pictures were based on neuroradiological studies by pneumoencephalography, ventriculography or by angiography. Generally these stud ies showed the presence and position of a lesion by displacement of normal brain structures and the picture was built up by interference. This was then converted by the experienced neurosurgeon into a plan for the craniotomy site and the trajectory of the surgical approach. Once the brain was exposed further pre-operative information was obtained by visual inspection and by palpation with the brain needle. These classical forms ofneuroradiology have largely been superseded by computerised tomography and by magnetic resonance imaging.

This volume contains selected contributions from the XIth Meeting of the European Society for Stereotactic and Functional Neurosurgery held in September 1994 in Antalyaffurkey. Most of the papers deal with the many therapeutic and technical advancements made in this field of neurosurgery. The emergence of new stereotactic methodologies such as frameless stereotaxy and other forms of neuronavigation have become an indispensable tool for all types of neurosurgical operations. An increasing number of young neurosurgeons takes an interest in the neurosurgical approaches to the treatment of movement disorders, chronic pain and epilepsy. This is a clear sign ofthe growing awareness of the long neglected fact that these neurosurgical treatments can be offered to large patient populations. Neurotransplantation as a novel treatment of Parkinson's disease has paved the way for the application of this technology for other indications. The pioneering work performed by the late Edward Hitchcock is reviewed here. There is a renewed interest in pallidotomy for dealing with certain forms of Parkinson's disease and certain aspects of this operation are discussed in another paper. Progress in the neurosurgical treatment of pain is dealt with by contributions on refined techniques of percutaneous cordotomy, DREZ operations and critical evaluations of spinal cord stimulation. A novel approach is a report on the experiences of treating cancer pain by intraspinal implantation of chromaffin cells. Several contributions cover the important issues of novel techniques for the study of neural dysfunction, peroperative monitoring with PET, microrecording, magneto-encephalography and other techniques.

The last ten years has witnessed a resurgence of interest in stereotactic surgery although this has been mainly in the field of the comparatively simple stereotactic biopsy of intracranial tumours. There is also evidence of a returning interest in functional neurosurgery other than pain which has always sustained high levels of endeavour. The present work comprises selected papers from a much larger group of interesting and important communications to the European Society for Stereotactic and Functional Neurosurgery. They represent modern views on a wide variety of stereotactic surgical topics from internationally acclaimed experts in this field. The neurosurgeon who has little or no acquaintance with this fruitful sub-specialty will be surprised to find very broad applications of the technique which is gradually replacing many con ventional neurosurgical procedures. This is particularly evident in the papers on tumours but there is also a section on the treatment of vascular disease which marks an extension of neurosurgical practice. The Society has always regarded technical advances as important and some of the most recent devel opments appear in this book. Finally, an exciting new development of neural transplantation marks the beginning of what may be an important part of neurological surgery in the future.

Local interstitial radiation therapy of intrinsic and inaccessible brain tumors is confronted with two major problems: 1. The tolerance of normal brain tissue, which is usually involved in local tumor irradiation, i.e. perifocal white matter edema and demyelinating effects, is crucial. 2. Data on radiation effects of implanted radioactive sources on neoplastic tissue, i.e. data on the radiosensitivity and on the biology of tumors, are still widely unavailable. In clinical practice the dose with which to achieve a given volume of tumor necrosis is roughly estimated. This report deals with the experimental findings of Iodine-125 and Iridium-I92 permanent implants in healthy and neoplastic brain tissue. Our own experimental findings are correlated with experimental data on Yttnul11-l)O irradiation from the literature. The study is directed to collect data on the tolerance non-tumoral brain tissue and to attempt to establish a dose-response relationship. Morphologic Changes in the Dog Brain Following Interstitial Iodine-125 Irradiation Iodine-I25 seeds (manufactured by 3 M Company, St. Paul, M. N.) with an activity of 3.55 mCi were permanently implanted under stereotactic conditions into the subcortical white matter of the gyrus coronalis of the left hemisphere in 6 beagle dogs. One animal with a non-radioactive seed implanted under similar operative conditions served as a control. The animals were allowed to survive 25, 46, 71, 94, 248, 368 days, respectively, after the implantation. The control animal survived 46 days. A detailed description of the experimental procedure is given elsewhere 16. 17.

These proceedings from the Xth Congress of the European Society for Stereotactic and Functional Neurosurgery in Stockholm reflect the growing interest in these fields of neurosurgery. It is the most extensive volume in this series of publications and it contains a large number of original articles pertaining to the most recent advances in stereotactic and functional neurosurgery. Not long ago stereotactic neurosurgery was considered an esoteric sub speciality practised only by those involved in treating movement disorders and pain. In the last decade we have witnessed the incorporation of stereotactic methodology in the management of common neurosurgical diseases, and the stereotactic technique is now practised in all major neurosurgical centers. As with other surgical techniques and tools, however, the utilization of stereotactic methods requires special knowledge and training. This book comprises articles which give insight into new stereotactic applications and technology. For example, the usage of stereotaxis without a frame and the so-called navigator systems in open tumor surgery is dealt with in two papers. The introduction and development of radiosurgery is closely linked to the advancement of stereotactic technique. Radiosurgical treatment of tumors and cerebrovascular diseases has been one of major achievements in modern neurosurgery. This publication contains several original reports illustrating the efficacy of radiosurgery in problematic neurosurgical diseases.
