Almost 200 years ago, German doctor Philipp Bozzini introduced the idea of endoscopy as a method of permitting visualisation of body cavities through their natural openings. First experiences with the use of this new method in different fields of medicine began in the early 20th century. Development of neuroendoscopy was related to the treatment of hydrocephalus. In 1910 Victor Lespinasse conducted the first neuroendoscopic intervention. He executed coagulation of choroid plexus in two children diagnosed with communicating hydrocephalus. The method was further developed by Walter Dandy who implemented ventriculography, worked out by himself in 1918, into the procedure of choroid plexus removal in hydrocephalic patients. For many, he is considered the father of neuroendoscopy. In 1923, William Mixter executed the first successful endoscopic ventriculostomy of the third ventricle. Spinal endoscopy began in the 1930's, but did not excite such interest as intracranial interventions. Introduction of the so-called shunt surgery for the treatment of hydrocephalus and application of operating microscopes in neurosurgery delayed progress of neuroendoscopy. It was not until the technical advances in optics and related fields of physics, that the neuroendoscopy resurged and has added a new dimension to neurosurgery. In 1963 GBrard Guiot described widespread possibilities of using endoscope in neurosurgery. In 1966 Harold Hopkins applied solid rod lenses in the construction of the endoscope, bringing it to its current standard of excellence. The introduction of the neurofiberoscope in 1973 by Takanori Fukushima opened further possibilities in the field of neuroendoscopy. The renaissance of endoscopy observed nowadays results from a general intention to limit invasiveness in neurosurgery.
