The microneurosurgical methods for brain surgery that were developed by Dr Yasargil in Zurich and extended by his colleagues worldwide are also of great use for disk surgery. The most significant of these benefits are: (1) prevention of bleeding by microscopic pre-emptive sealing of vessels so that surgery can be as thorough as needed, (2)smaller incisions and less trauma to nearby tissues so that patients can wake up feeling better rather than worse, and (3)greater safety for nerves and vessels because of the magnified and illuminated view.
