Previously considered the domain of the otolaryngologists, the endoscopy is now a common part of the armamentarium of a neurosurgeon. Neuroendoscopy or endoscope-assisted microsurgery is now being used in almost all routine procedures performed in the neurosurgical operating room. Hands-on training has become essential to learn the basics of neuroendoscopy, even for neurosurgeons well accustomed to the use of microscopes. ⋯ In this "tech-savvy era," various cadaver or synthetic models are readily available for endoscopy training in a virtually simulated environment. In accord with the results of a surveys conducted by individual groups and societies, the authors firmly believe that incorporation of endoscopy in the neurosurgical curriculum would add a new dimension to the existing protocol. There is an urgent need for dedicated endoscopy training programs similar to postresidency fellowships in addition to translational research and establishment of dedicated societies to formulate guidelines for such research and monitor its progress.

The technology and instrumentation for neuroendoscopy are described: endoscopes (principles, designs, applications), light sources, instruments, accessories, holders, and navigation. Procedures for cleaning, sterilizing, and storing are included. ⋯ Neuroendoscopic instrumentation is now an established technique in neurosurgical practice and is experiencing rapid development (stereoscopy, integrated operating room).

Neuroendoscopy: general aspects and principles.
When used in medicine, endoscopy describes a procedure used to see inside various parts of the body, such as the interior surfaces of an organ, by inserting a tube through a natural or created orifice. The instrument may have a rigid (borescope) or flexible (fiberscope) tube; it provides an image for visual inspection, photography and video-endoscopy and enables acquisition of biopsy specimens, removal of lesions, and retrieval of foreign objects. It is imperative that young neurosurgeons and residents become familiar and comfortable with endoscopic techniques, and it is hoped that they can contribute to the evolution and development of these surgical methods.

To term and describe neuroendoscopic techniques. ⋯ Endoscopic techniques are a valuable addition to the neurosurgeon's armamentarium. Endoscopes are especially beneficial in deep and narrow surgical approaches and when "looking around a corner" is required.

Endoscopy for hydrocephalus caused by infectious diseases presents clear challenges to the surgeon. Hydrocephalus caused by tuberculous meningitis is a good model to explore many of the issues that should be considered in the management of these patients. Tuberculous hydrocephalus may be communicating or noncommunicating management options include medical treatment (for communicating hydrocephalus), ventriculoperitoneal shunting, and endoscopic third ventriculostomy. ⋯ However, this also must be weighed against the surgical and long-term complications associated with the procedures used. There are specific endoscopic challenges that occur as the result of abnormal anatomy and the fact that hydrocephalus presents during the acute phase of the disease, rather than being postinfectious. In this article we examine the arguments for various therapeutic approaches and discuss the gathering experience in the literature about endoscopy in tuberculous meningitis in the context of overall management options.
