1.It is not easy to cause intracranial or abdominal infection and minimize intraoperative complications; 2.It is not affected by the growth and development of children and avoids the pain of multiple tube changes; 3.The operation is relatively simple and takes less time compared with traditional surgery; 4.It does not cause subarachnoid atresia that may be caused by traditional transendocranial ventriculostomy and lead to surgical failure; 5.The neuroendoscopic technique is less traumatic, more effective, less postoperative complications, faster recovery, and more in line with human physiology; 6.Compared with microscopy, endoscopic surgery is less traumatic, has a clearer field of view, and can reveal a wider range of lesions at close range. Compared with microscopy, endoscopic surgery is less traumatic, has a clearer field of view, reveals a wider range of lesions, and allows for close observation of lesions, which greatly reduces surgical injuries, complications, and improves surgical efficacy. The combination of neuroendoscopic technology and other new technologies, using small incisions, makes some neurosurgical procedures more accurate and delicate, and further reduces surgical trauma, even to “no trace of snow”. Compared with the operating microscope, neuroendoscopic surgery has three advantages: 1qThe endoscopic view tube itself has a lateral view, which can eliminate the blind area of intraoperative field. Neuroendoscopic-assisted microneurosurgery overcomes many visual dead spots in microsurgery, resulting in more delicate surgery with better results. It provides a panoramic view when reaching the lesion, a “close-up” view of the lesion, and a magnified image to identify the important nerve and vascular structures lateral to and around the lesion and to guide the removal of the surrounding lesion tissue. The angled endoscope shows corners of the pontocerebellar triangle and basal pool that cannot be reached by the surgical microscope. In addition, operating under direct neuroendoscopic vision can avoid bleeding caused by blind puncture. 2q With the help of stereotactic or neuronavigation technology, precise positioning can be achieved, and it can deal with areas that are difficult to reach by conventional surgery, and it is especially suitable for surgery of lesions in deep brain or midline areas. In deeper fields, the light source of the surgical microscope is attenuated, while the neuroendoscope is illuminated at close range, and although the stereoscopic image is slightly different from the microscopic image, the clarity of the deep field is significantly better than that of the surgical microscope. The 3q neuroendoscope is more suitable for microbone window access and less invasive surgery. The diameter of the neuroendoscope varies from 0.6 to 6 mm in size, which causes little damage to brain tissue; most neuroendoscopic procedures use a microbony window approach, avoiding trauma to brain tissue from bone flap craniotomy. The long endoscope body and small cross-section are suitable for operation in narrow cavities and orifices. These features of the neuroendoscope help to better visualize lesions or important structures around the skull, and are especially helpful in operating on deep lesions (e.g., basilar aneurysms) within narrow gaps in microsurgery, reducing the extent of craniotomy and avoiding excessive exposure. The surgical microscope; allows for increased local illumination and softer light. [2]
