13th World Congress of Neurological Surgery

(June 19-24, 2005, Marrakesh, Morocco)




The 13th International Congress of Neurological Surgery under the auspices of the Neurosurgical Society of Morocco and the World Federation of Neurosurgical Societies promises to be an absolutely unique and outstanding educational event. This is the first International Congress of Neurological Surgery ever to be held on the continent of Africa. The Scientific Program has been arranged to offer profound educational experiences to neurosurgeons at every level of their respective careers. However, it is focused on the young neurosurgeon and particularly on those neurosurgeons who work in the developing areas of the world. The texts of the Outstanding Scientific Publications speak for themselves in delineating the level of expertise that prevails during this Congress, and this volume records a truly historic event in global neurosurgery and is a tribute to those individuals responsible for organizing the superb International Congress in Marrakesh.

The 13th World Congress of Neurological Surgery held in Marrakech in June 19-24, 2005 has succeeded in joining together the highest number of scientific presentations and speakers ever registered in the previous world congresses. 2264 abstracts have been retained by the scientific program committee presented by 1935 speakers. Although the majority of these abstracts have been gathered in a CD ROM, we have decided to publish the proceedings of the congress so that all young neurosurgeons who participate in the event take advantage from it. The Publisher Medimond in charge of this publication, contacted all the speakers who have sent their abstracts to the Congress asking them to send their papers. Only the papers sent before the deadline were included in this book.
All the papers were processed according to the format and the contents that was initially adopted by their authors when they sent the papers to Medimond. The editors have only gathered and organized them in different topics and chapters. Therefore, the contents of these papers is under the sole responsibility of their authors, and cannot by any means involve the responsibility of the Editor.
Our aim is to provide the participants in the congress a book that will not only be a scientific reference tool for continuing medical education, but also be a souvenir book that will remind them of the 13th World Congress of Neurological Surgery and of the fascinating city of Marrakech.
On behalf of the Organizing Committee of the 13th World Congress and myself, I would like to express my thanks to Medimond for their collaboration, and for having printed the book on time to be available during the congress.

Abdeslam El Khamlichi, M.D.
President of the 13th World Congress
