Minimally invasive neuroendoscopic surgery is a surgical procedure that utilizes the neuroendoscope as a surgical tool to carry out a series of treatments for central nervous system disorders through the natural cavities of the human body or through micro-bone holes in the skull, combined with modern navigation, ultrasound and stereotactic equipment. It makes full use of the spacious surgical field and wide operating angle provided by the neuroendoscope, and at the same time allows the neuroendoscope to go deep into the surgical area and observe the anatomical structure of the surgical area at close range. By observing the anatomical structures at close range, the lesion can be removed more safely and thoroughly, and normal tissues and structures can be preserved, which can significantly reduce surgical complications and hospitalization costs, and at the same time achieve a better cosmetic effect. This surgical method is similar to “standing outside the door and looking at the house becomes entering the house and looking at the house” compared with the past surgical methods. It is currently the most advanced surgical method in neurosurgery and represents the direction of modern neurosurgery. This technology is also accepted and loved by the majority of patients for its small surgical trauma, high lesion resection rate, fast postoperative recovery and short hospitalization time. At present, we mainly carry out the treatment of the following diseases: 1, minimally invasive treatment of intracranial tumors, including gliomas, meningiomas, pituitary tumors, saddle node meningiomas, craniopharyngiomas, chordomas, Lacke’s cysts, ventricular tumors, etc. 2, minimally invasive treatment of hydrocephalus, including hydrocephalus, obstructive hydrocephalus, intracranial infections, cerebrospinal fluid leakage, etc. 3, minimally invasive treatment of congenital diseases, including arachnoid cysts, skull-cervical junction deformities, and cervical and neck junctional malformations. Minimally invasive treatment of congenital diseases, including arachnoid cyst, craniocervical junction deformity, etc. 4. Minimally invasive treatment of cranial neuropathy, including trigeminal neuralgia, facial muscle spasm, glossopharyngeal neuralgia, etc. 5. Minimally invasive treatment of cerebral hemorrhage, including hypertension, cerebral ventricular hemorrhage, chronic subdural hematoma, etc. 6. Minimally invasive treatment of spinal diseases, including cervical and lumbar intervertebral disc herniation, spinal stenosis, spinal cord tumor, etc.
