There is hardly an international meeting of importance that would not have Professor de Oliveira either as a speaker or a panellist. Professor de Oliveira’s name has been closely associated with neurosurgical anatomy and microsurgical technique. He obtained his medical degree from Santa Catarina Federal University School of Medicine in Florianopolis in Brazil in 1969. His neurosurgical residency in Montevideo in Uruguay followed by a fellowship in microsurgical anatomy at the University in Florida in Gainesville. Dr de Oliveira maintains a close association with the Department of Neurosurgery and the University of Florida where he has been an Associate Professor from 1989 and Professor of Neurosurgery from 1996. Between 1985 and 1998 Dr de Oliveira headed the São Paulo Neurological Institute and subsequently became the Director of the Institute of Neurological Sciences in São Paulo while heading the Department of Neurosurgery at the Medical Sciences School, State University of Campinas – UNICAMP. Dr de Oliveira is the President of the Brazilian Neurosurgical Congress in 2008.

There is hardly any cranial region or surgical approach that has not Dr de Oliveira’s name attached to it. Dr de Oliveira has been a co-author of numerous seminal publications in neurosurgical anatomy and microsurgical techniques, and the textbook he co-edited with Dr Laligam Sekhar Cranial Microsurgery: Approaches and Techniques is a classic. Professor de Oliveira has not only published extensively, but he generously shares his surgical knowledge and skill around the globe. Professor de Oliveira is the Director of an excellent annual hands-on course in neurosurgical anatomy based in Braga, Portugal.

Dr Rhoton does not need an introduction. Everyone knows that Rhoton is not a special alloy, the secret behind the unfading popularity the Rhoton set of microsurgical instruments, but one of the most influential figures in the world of neurosurgery in last 50 years. To many Dr Rhoton’s name is synonymous with neurosurgical anatomy and there are good reasons for it. Virtually every issue of Neurosurgery caries one or more Dr Rhoton’s papers and his Cranial Anatomy and Surgical Approaches feature on every neurosurgeon’s bookshelf. Dr Rhoton is not just a great neurosurgeon, neurosurgical anatomist, but also a caring physician. Cambridge Lectures in Neurosurgical Anatomy are proud to adopt his words … to make the delicate, awesome, and fateful work of the neurosurgeon more accurate, gentle, and safe. as the Lectures’ official motto.

Professor Guilherme Carvalhal Ribas

Professor Guilherme C. Ribas obtained his medical degree from the Federal University of São Paulo in São Paulo in 1977. Between 1978 and 1982 he trained in neurosurgery at the University of São Paulo under Professor Gilberto Machado de Almeida and at the University of Virginia under Professor John A. Jane. In 1985 he was a visiting research fellow at Professor Albert Rhoton’s laboratory at the University of Florida.

He obtained a doctorate in Neurology in 1991 and in 2005 became a Professor of Surgery at the University of São Paulo’s Medical School. He is oversees graduate and post-graduate courses in neuroanatomy at the Department of Surgery headed by Professor Aldo Junqueira Rodrigues Jr. Professor Ribas’ research focused on microneurosurgical anatomy and on cranial neurosurgical techniques has produced numerous high-impact publications in this field. His neurosurgical practice is based at the Hospital Israelita Albert Einstein in São Paulo, and he specialises in surgery for intrinsic and extrinsic brain tumours.

Since 1995 Professor Ribas teaches Surgical Neuroanatomy at the Department of Neurosurgery of the University of Virginia, where in 1997 he was appointed Professor of Clinical Neurosurgery. He also serves as a faculty on “Sulcus, Gyrus and Ventricles” hands on course in neurosurgical anatomy held also annually in Braga, Portugal, since 2003, together with Professors Evandro de Oliveira, Albert Rhoton, Ugur Ture and Antonio Cesar Mussi. He was the fist guest speaker of the Cambridge Lectures in Neurosurgical Anatomy in 2005 and since has served as a faculty and organiser of this course.

Professor Ribas is a keen photographer and he managed to carry this passion with him into the field of neurosurgical education. Professor Ribas is one of the pioneers of neurosurgical 3D photography, projection and printing. His world class collection of anatomical and per-operative images stands out not only because of cleverly planned and meticulously prepared dissections, the clarity of photography, but also because of its exceptional aesthetic value.
