[[1922]]-[[1924]]

The study of [[intracranial aneurysm]]s has grown at an astounding rate since Sir [[Charles Symonds]] association of hemorrhage within the subarachnoid space to intracranial aneurysms in [[1923]].

[[Neuroendoscopy]] was described initially in the year [[1910]] by Victor Darwin Lespinasse (An urologist) where the [[lateral ventricle]]s were accessed using a rigid cystoscope to fulgurate the [[choroid plexus]] as a measure to reduce [[cerebrospinal fluid production]] in hydrocephalic children
((Dandy WE. An operative [[procedure]] for hydrocephalus. Bull Johns Hopkins Hosp. 1922;33:189)).

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.

The division of Neurosurgery in [[Toronto]] was created in [[1923]].

Dr. Abdulkadir Cahit Tuner became the first [[neurosurgeon]] with a degree in [[Turkey]] in [[1923]]. The first neurosurgery department was established in [[Istanbul]] in 1923, and the first training program began in the late 1940s
