In neurosurgical practice, laser has been used for a long time in both diagnosis and treatment. Laser technology is developing day by day, new devices are being made and new areas of use are appearing. Laser devices have not become widespread due to their high energy and the sensitivity of the tissue they are used on. We hope that in the near future, more effective and safer laser devices will be developed for neurosurgeons and techniques that allow their widespread use will be found.

The first use of lasers in neurosurgery goes back to 1966. Diagnostically, it is most commonly used to measure cerebral blood flow during surgery. For therapeutic purposes, it can be used like a scalpel to cut hard tumors in brain tumors. With laser technology, vessels can be joined end-to-end (microanostomosis) or the diseased vessel area can be bypassed by by-pass. Laser-induced thermal therapy can be used for epilepsy and brain tumors. Laser therapy may also have side effects such as cerebral hemorrhage due to vascular damage, heat damage, infection and seizures.
