OBJECTIVETo review the history, development, and reality of neuronavigation surgery in China and to discuss the future of neuronavigation surgery.

DATA SOURCESPubMed, the China Knowledge Resource Integrated Database, and the VIP Database for Chinese Technical Periodicals were searched for papers published from 1995 to the present with the key words "neuronavigation," functional navigation," "image-guided," and "stereotaxy." Articles were reviewed for additional citations, and some information was gathered from Web searches.

STUDY SELECTIONArticles related to neuronavigation surgery in China were selected, with special attention to application to brain tumors.

RESULTSSince the introduction of neurosurgical navigation to China in 1997, this core technique in minimally invasive neurosurgery has seen rapid development. This development has ranged from brain structural localization to functional brain mapping, from static digital models of the brain to dynamic brain-shift compensation models, and from preoperative image-guided surgery to intraoperative real-time image-guided surgery, and from application of imported equipment and technology to use of equipment and technology that possess Chinese independent intellectual property rights.

CONCLUSIONSThe development and application of neuronavigation techniques have made neurological surgeries in China more safe, precise and effective, and less invasive, and promoted the quality of Chinese neurosurgical practice to the rank of the most advance and excellence in the world.

OBJECTIVETo investigate the effect of neuroendoscope on surgery.

METHODS315 patients were treated with neuroendoscope. Endoscopic neurosurgery (EN) was used in 219 patients, endoscope-assisted microneurosurgery (EAM) in 72, and endoscope-controlled microneurosurgery (ECM) in 24.

RESULTS201 (91.8%) of the 219 patients underwent EN effectively. In 72 patients who underwent EAM there was less retraction during tumor removal and visual control was improved. 21 (87.5%) of the 24 patients underwent ECM effectively. No severe complications were observed.

CONCLUSIONNeuroendoscopy can reduce tissue trauma, improve visualization during tumor removal, and reduce complications.

Precision neurosurgery concept as well as the establishment of it's technical platform, have played essential roles in promoting the modern surgical management of brain gliomas in China.In the past decade,the multidisciplinary integration of medical sciences and technology innovations has significantly promoted the clinical implementation of new imaging and novel navigation technology.With active clinical translational research and practice,precision neurosurgery has developed from "startup prologue" (simple anatomical navigation) to "precision neurosurgery 1.0" (intraoperative MRI with multimodal neuronavigation),followed by "precision neurosurgery 2.0" (informative and systematic upgrading).In the past decade,Chinese researchers have made significant and remarkable achievements in precision neurosurgery through continuous efforts and innovation.In the future,state-of-art technologies such as artificial intelligence on deep learning and machine learning,multimodal real-time navigation,intraoperative optical imaging,and targeted molecular imaging technology will promote the development of precision neurosurgery in a coordinated manner, leading to the advent of "precision neurosurgery 3.0".

Neurosurgery is a highly specialized field: it often involves surgical manipulation of noble structures and cerebral retraction is frequently necessary to reach deep-seated brain lesions. There are still no reliable methods preventing possible retraction complications. The objective of this study was to design work chambers well suited for transcranial endoscopic surgery while providing safe retraction of the surrounding brain tissue. The chamber is designed to be inserted close to the intracranial point of interest; once it is best placed it can be opened. This should guarantee an appreciable workspace similar to that of current neurosurgical procedures. The experimental aspect of this study involved the use of a force sensor to evaluate the pressures exerted on the brain tissue during the retraction phase. Following pterional craniotomy, pressure measurements were made during retraction with the use of a conventional metal spatula with different inclinations. Note that, although the force values necessary for retraction and exerted on the spatula by the neurosurgeon are the same, the local pressure exerted on the parenchyma at the edge of the spatula at different inclinations varied greatly. A new method of cerebral retraction using a chamber retractor (CR) has been designed to avoid any type of complication due to spatula edge overpressures and to maintain acceptable pressure values exerted on the parenchyma.
