目的探讨术中神经电生理监测(intraoperative neurophysiological monitoring,IONM)在后颅凹肿瘤手术中监测方法及应用价值。方法应用脑干听觉诱发电位、体感诱发电位、运动诱发电位等技术,在40例后颅凹肿瘤手术中进行IONM,记录技术参数和监测结果,进行术后早期随访。结果 13例行脑干功能监测,波形均未见明显变化;36例行面神经监测,解剖保留34例(其中9例同时行脑干和面神经监测);27例行后组颅神经监测,26例解剖保留。术后影像学提示37例(92.50%)全切或根治性切除,3例(7.50%)大部切除。出院时,卡氏功能状态评分在70分以上39例,占95.00%。结论在后颅凹肿瘤手术中应用IONM可有效提高手术安全性,降低手术导致的神经损伤病残率,提高患者的生存质量。
Objective To investigate the method and application value of intraoperative neurophysiological monitoring (IONM) in the diagnosis of posterior fossa tumor. Methods The brainstem auditory evoked potentials, somatosensory evoked potentials and motor evoked potentials were used to perform IONM in 40 cases of posterior fossa tumors. The technical parameters and monitoring results were recorded and the patients were followed up early. Results Thirteen patients underwent brainstem function monitoring without obvious changes in waveform. Thirty-six patients underwent anatomical surveillance (9 of them underwent brainstem and facial nerve monitoring simultaneously); 27 underwent cranial nerve monitoring and 26 Anatomy retention. Thirty-seven cases (92.50%) underwent radical resection or radical resection and 3 cases (7.50%) underwent resection. At discharge, card’s functional status score was above 70 points in 39 cases, accounting for 95.00%. Conclusion The application of IONM in posterior fossa tumor can effectively improve the operation safety, reduce the morbidity of nerve injury caused by surgery and improve the quality of life of patients.
