When performing open resection of brain tumors, ultrasound can also be used to accurately localize the tumor in real time. Using this method, the neurosurgery department of Xinhua Hospital in Hubei Province operated on patients with brain tumors in the motor area, all of which were successful. Ms. Li, a patient from Huangpi, who was admitted to the hospital yesterday lying down, walked out of the hospital with a smile on her face. Determining the location of brain tumors precisely and in real time has been a difficult problem in the implementation of surgery, especially for small tumors in the motor area. The traditional method is to puncture and probe in the brain with a brain puncture needle, but this method is not easy to locate accurately and can cause damage to the brain. Currently, the advanced method is surgical navigation, which can show the location of the tumor before surgery, but during surgery, many factors can cause the tumor to shift and it is difficult to find the exact location of the tumor. Using ultrasound to locate brain tumor, this kind of ultrasound is finer and smaller than the conventional ultrasound, which can accurately find the location of tumor. According to Dr. Liu Hongzhao, director of neurosurgery of Hubei Xinhua Hospital, with this method, the location of brain tumor can be accurately located in real time, with small surgical incision, accurate positioning and less trauma, which improves the total resection rate of brain tumor and reduces surgical complications.
