=====Neuroendoscope===== Advances in [[video]] and [[fiber optic]]s since the 1990s have led to the development of several commercially available high-definition neuroendoscopes. This technological improvement, however, has been surpassed by the [[smartphone]] revolution. With the increasing integration of smartphone technology into medical [[care]], the introduction of these high-quality computerized communication [[device]]s with built-in [[digital camera]]s offers new possibilities in [[neuroendoscopy]]. The aim of a study of Mandel et al., was to investigate the usefulness of smartphone-endoscope integration in performing different types of [[minimally invasive neurosurgery]]. They presented a new surgical [[tool]] that integrates a smartphone with an [[endoscope]] by use of a specially designed adapter, thus eliminating the need for the [[video]] system customarily used for endoscopy. They used this novel combined system to perform minimally invasive surgery on patients with various neuropathological disorders, including [[cavernoma]]s, [[cerebral aneurysm]]s, [[hydrocephalus]], [[subdural hematoma]]s, [[contusion]]al [[hematoma]]s, and spontaneous [[intracerebral hematoma]]s. The new endoscopic system featuring smartphone-endoscope integration was used by the authors in the minimally invasive surgical treatment of 42 patients. All procedures were successfully performed, and no [[complication]]s related to the use of the new method were observed. The quality of the images obtained with the smartphone was high enough to provide adequate information to the neurosurgeons, as smartphone cameras can record images in high definition or [[4K]] resolution. Moreover, because the smartphone screen moves along with the endoscope, surgical mobility was enhanced with the use of this method, facilitating more intuitive use. In fact, this increased mobility was identified as the greatest benefit of the use of the smartphone-endoscope system compared with the use of the neuroendoscope with the standard video set. [[Minimally invasive]] approaches are the new frontier in neurosurgery, and technological [[innovation]] and integration are crucial to ongoing progress in the application of these [[technique]]s. The use of smartphones with endoscopes is a safe and efficient new method of performing endoscope-assisted neurosurgery that may increase surgeon mobility and reduce equipment [[cost]]s ((Mandel M, Petito CE, Tutihashi R, Paiva W, Abramovicz Mandel S, Gomes Pinto FC, Ferreira de Andrade A, Teixeira MJ, Figueiredo EG. Smartphone-assisted minimally invasive neurosurgery. J Neurosurg. 2018 Mar 1:1-9. doi: 10.3171/2017.6.JNS1712.

The flexible high-definition chip-camera endoscope has emerged as a potential remedy for the shortcomings of available instruments by combining superior flexibility and image quality in order to better operate within spatially constrained intraventricular operations. The use of high definition flexible camera-on-a-chip endoscopy may provide enhanced intra-operative visualization and application for intraventricular neurosurgery ((Friedman GN, Grannan BL, Nahed BV, Codd PJ. Initial Experience with High Definition Camera-On-a-Chip Flexible Endoscopy for Intraventricular Neurosurgery. World Neurosurg. 2015 Aug 5. pii: S1878-8750(15)00926-2. doi: 10.1016/j.wneu.2015.07.056.

This type of surgery requires a team of specialists that may include ENT (ear, nose, and throat) surgeons, neurosurgeons, and radiologists. Before endoscopic skull base surgery was developed, the only way to remove growths in this area of the body was by making an opening in the skull. Under some circumstances, this type of surgery may be necessary. see [[Endoscopic endonasal approach]] ===Vascular=== see [[Endoscopic endonasal approach for intracranial aneurysm]]
