Dear neurosurgical colleagues from all over the world,

We are honoured to invite you all to Prague, the heart of Europe, for the 4th MASSIN Interim Meeting in Prague in May 25–27, 2023. The MASSIN – The Madjid Samii Society of International Neurosurgeons – was founded in 2007 by students, collaborators, and friends of M. Samii. In its 16 years of existence, its congresses have become the best that the world of neurosurgery can offer. Unlike the large WFNS events, MASSIN allows friendly, personal contacts and open discussion of all the issues neurosurgery faces at present.

The congress in Prague is attended by top experts from all over the world. The scientific programme guarantees to bring together the most up-to-date knowledge in the field of central and peripheral nervous system, in the skull base, in benign and malignant oncology, in vascular neurosurgery, in spondylosis surgery, in new technologies, robotics and artificial intelligence. The MASSIN includes transtemporal approaches and intensive EC-IC bypass Course.

The contemporary world and neurosurgery, WFNS, addresses a number of challenges. The MASSIN with its programme will contribute to strengthen friendship and international world cooperation of global neurosurgery. The congress is organized by GUARANT International, leader in PCO services in the Czech Republic and the CEE region.
