The transoral approach to the upper cervical spine has not gained wide acceptance. A reliable intraoperative method to determine the necessary extent of dissection and degree of decompression, as well as to evaluate spinal cord function, should improve the safety and applicability of the transoral approach. Four cases of anterior cervical cord compression were successfully treated by odontoid resection employing a microsurgical transoral approach. Intraoperative fluoroscopy monitored the depth of dissection and adequacy of decompression. Somatosensory cortical evoked potentials (SSEP) allowed assessment of spinal cord function that could be correlated with surgical decompression. In addition, follow-up examination revealed that SSEP was an intraoperative prognosticator of subsequent neurologic improvement.
经口入路上颈椎手术尚未得到广泛认可。一种可靠的术中方法，用于确定必要的解剖范围和减压程度，以及评估脊髓功能，应能提高经口入路的安全性和适用性。采用显微经口入路齿状突切除术成功治疗了4例颈髓前部受压患者。术中透视监测解剖深度和减压充分性。体感皮层诱发电位（SSEP）可用于评估脊髓功能，并与手术减压情况相关联。此外，随访检查显示SSEP是术后神经功能改善的术中预测指标。
