Minimally invasive neurosurgery With the development of microscopic technology and the use of the latest technology, we have carried out a variety of minimally invasive surgical techniques, which not only greatly reduce the pain of surgery and improve the efficacy of treatment, but also reduce the hospitalization time and save the treatment cost. 1. Transsphenoidal approach to remove pituitary adenoma: conventional pituitary adenoma removal requires craniotomy, but our surgery to remove pituitary adenoma does not require craniotomy, only nasal entry can satisfactorily remove the tumor, which not only avoids the pain of craniotomy, but also leaves no scar and has no effect on appearance. The postoperative recovery is fast, no stitches need to be removed, and the patient can be discharged from the hospital in 5-7 days after surgery. Our department has carried out more than one hundred cases with good results. 2. Stereotactic intracranial hematoma clearing surgery: without opening the skull, only a small incision is made on the scalp, using stereotactic technology, we can accurately reach the center of the hematoma and aspirate the hematoma with an error of no more than 1 mm, and the operation time is very short, no more than one hour, and it can be completed under local anesthesia. Patients, greatly reducing the risks associated with surgical strikes. Our department has carried out more than 100 cases with good results. 3. Intracerebral hematoma removal with a small bone window for hypertensive cerebral hemorrhage: Based on the skillful microscopic neurosurgery technique, we use a small incision to perform intracerebral hematoma removal in a bone window of only 3 cm in diameter, which causes little damage to the brain tissue, and the operation is short, with little bleeding, avoiding the large trauma and more bleeding of conventional craniotomy, and the hospitalization time is significantly shortened and better recovery is achieved. We have carried out more than two hundred cases with obvious results. 4.Semi-vertebral plate approach to resect intravertebral canal tumor: With superb micro-neurosurgery technology and familiar micro-anatomical knowledge, we have carried out the semi-vertebral plate approach to resect intravertebral canal tumor earlier in China, the surgical incision is greatly reduced than the conventional one, and the tumor can be removed by biting off half of the vertebral plate, which avoids the extensive damage to the spine by conventional surgery, reduces trauma and completely avoids the impact of surgery on the spine. The patient can get out of bed early and the hospital stay is significantly shortened.
