Intraoperative arousal for minimally invasive resection of glioma in the language area

  ”Intraoperative wakeup” was a success This “intraoperative wakeup” surgery, which was performed by a multidisciplinary team of doctors from neurosurgery, anesthesiology, rehabilitation and neurology, was ultimately a success. The multidisciplinary team precisely removed the “left temporoparietal glioma” that was growing in the speech area of the patient’s brain for a female secondary school teacher in her 30s in Guangxi, and maximized the patient’s speech, motor functions and chances of returning to the lectern.  The female teacher had been losing her speech during lectures since April of this year, and later developed seizures and other epileptic symptoms in her sleep. After surgery, a repeat MRI confirmed that her tumor had been completely removed and she was not only able to move around normally, but also had no impairment in verbal communication. Currently, she has recovered and discharged from the hospital and is undergoing post-operative radiotherapy. According to Prof. Dai Qilin, the patient’s epileptic symptoms are related to the glioma, and as long as the glioma does not recur, anti-epileptic treatment can be ended in two to three years.  ”According to Associate Professor Yang Chao of the Department of Neurosurgery at Zhongshan First Hospital, once the tumor is next to the functional areas of language and body movement, the craniotomy to remove it may result in serious language and movement disorders after the surgery in case these functional tissues are injured.  Craniotomy with “intraoperative arousal” method is performed by injecting anesthetic into the patient’s scalp and meninges to block the pain. In this way, the patient is awakened after the craniotomy, and the awake patient can cooperate with the surgeon during the surgery to determine the location of the functional areas by the response to cortical electrical stimulation, and thus perform a precise resection.
