Sun Z, Wang Y, Cai X, et al. - Researchers conducted this retrospective study to assess the benefits of endoscopic visualization and the value of full endoscopic vascular decompression (EVD) by describing the surgical outcomes of 20 patients with trigeminal neuralgia (TN) who received EVD between April 2018 and October 2019. All patients had EVD through the suboccipital retrosigmoid approach without microscopy at any stage. Abnormal muscle response and brainstem auditory evoked potentials have been routinely monitored throughout the procedure. According to findings, all 20 patients with extreme preoperative pain (BNI of 5) gained immediate relief or full control of pain following surgery (BNI of 1 to 2). Vascular conflicts were found in all of the patients during surgery. None of the patients suffered hearing loss, facial paralysis, intracranial infection, cerebrospinal fluid leakage, cerebral hemorrhage, or death following surgery. EVD can provide a clear surgical field of view when conducted by endoscopic skilled surgeons, and reduce the risk of surgical injury. The results suggest that EVD is a safe and efficient surgical procedure used to treat TN.
