The goal of the present article was to describe our dissection training system applied to a variety of endoscopic endonasal approaches. It allows one to perform a 3D virtual dissection of the desired approach and to analyze and quantify critical surgical measurements. ⋯ The present model results are found to be effective, providing a valuable representation of the surgical anatomy as well as a 3D visual feedback, thus improving study, design, and execution in a variety of approaches. Such a system can also be developed as a preoperative planning tool that will allow the neurosurgeon to practice and manipulate 3D representations of the critical anatomic landmarks involved in the endoscopic endonasal approaches to the skull base.

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 ⋯ The effectiveness of neuroendoscopic management of middle fossa arachnoid cysts has not yet been superseded by any other surgical treatment.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.

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.

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.

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).
