Stereotactic electroencephalography (SEEG) originated in France and was invented by TALAIRACH and BANCAUD in the 1950s and 1960s. The two men carried out this great work without MRI and indeed enabled many patients with drug-refractory epilepsy to find the epileptogenic zone with this technique and thus obtain a seizure-free post-surgical period. However, for a long time, the French did not promote this technique to the world because it was more difficult to spread the surgical technique. When a new generation of robotic devices was created, the placement of electrodes no longer needed to be strictly perpendicular to the brain surface as in the past, and the fusion technology of vascular and magnetic resonance ensured safety, both ROSA and Neurospace, making the promotion of this technique a spring. In 2010, Sanbo Brain Hospital decided to introduce the technology. From 2010 to 2012, for three consecutive years, Professor Liu Xingzhou, then head of the Department of Neurology, personally went to France to study, and in 2011, Professor Luan Guoming, director of the Epilepsy Center, went to France to observe and learn the whole procedure and design theory of electrode placement, and decided to introduce ROSA. Since then, I have been involved in the clinical work and research of SEEG. Now four years later, nearly 200 patients have undergone SEEG and more than 60% of them have been seizure-free through the procedure. It is now starting to gain popularity in China, including the Sanjiu Brain Institute, the San-O1 Hospital, and the Xuanwu Hospital, and its popularity is a great thing for epilepsy patients. SEEG is not a foolproof technique, the design of the electrodes and the accuracy of their placement are very important, so it is very important to choose where to do it, who will design it and who will do it.
