The purpose of this study is to analyze symptomatic middle fossa arachnoid cysts and describe the advantages of the endoscopic technique to manage those cases that should be resolved surgically. ⋯ The effectiveness of neuroendoscopic management of middle fossa arachnoid cysts has not yet been superseded by any other surgical treatment. It has been shown to be a simple, reliable, and fast procedure, with a low rate of complications and shorter hospital stay. In general, patients can resume their usual daily activities quite soon.

Endoscopic third ventriculostomy (ETV) is the treatment of choice for noncommunicating hydrocephalus. In the last decade, its routine use also has taken place in patients who have previously undergone shunt placement (secondary ETV). ⋯ Shunt infection should not be considered a contraindication to ETV, even if the success rate may be lower. Considering the higher complication rate and higher risk of intraoperative failure, secondary ETV should be performed by expert neuroendoscopists.

Massive intracerebral and intraventricular hemorrhages require aggressive and rapid management to decrease intracranial hypertension. The amount of intraventricular blood is a strong prognostic predictor, and its fast removal is a priority. Neuroendoscopy may offer some advantages over more traditional surgical approaches. ⋯ Early neuroendoscopic surgery is a feasible approach, allowing, in most instances, rapid clinical and radiological improvement.

In the modern era, neuroendoscopy has had an increasingly prominent role in neurosurgery. As attention has focused the development of minimally invasive surgical methods, neuroendoscopy has advanced both as an independent treatment modality for various neurologic disorders and as an adjunct to microneurosurgery. ⋯ In addition to its advantages, neuroendoscopy is associated with unique obstacles that must be anticipated, appreciated, and accounted for to prevent complications. This article outlines techniques to reduce and manage complications during more common intraventricular neuroendoscopic procedures including endoscopic third ventriculostomy (ETV), colloid cyst resection, tumor biopsy and resection, and treatment of loculated hydrocephalus.

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).
