摘要
目的探讨Nucleus24Contour在极重度聋患者中的手术置入方法及其术后产生电听觉所需的电流量。方法对使用Nucleus24Contour组及Nucleus24M组患者的手术方法及术后产生电听觉所需要电流量进行比较。结果82例患者中,只有1例患者置入电极28环,其余81例患者32环电极全部置入。31例患者于耳蜗开窗时有少量淋巴液流出,2例耳蜗骨化者耳蜗开窗时未见淋巴液。术后7例患者出现较轻微的并发症。使用Nucleus24Contour组术中测得神经反应测试阈值明显减低,且在第一通道有统计学意义(P<0.05)。结论Nucleus24Contour手术置入容易,创伤小,耗电量少,是极重度感音神经性聋患者新型的、安全有效的置入物。
Objective:To report the surgery and the postoperative outcomes with Nucleus 24 Contour electrode array in patients suffered from profound sensorineural hearing loss.Method:The surgery and postoperative current level making electrical hearing are compared between the group with Nucleus 24 contour and the group with Nucleus 24 M.Result:Among the 82 cases,32 electrodes were inserted in 81 cases, 28 electrodes in 1 case. The intraoperative small CSF flowing occurred in 31 cases and no CSF flowing occurred in 2 cases. The slight postoperative complications of the surgeries occurred in seven patients.The postoperative NRT threshold of the group with Nucleus 24 Contour was lower than the group with Nucleus 24M .There was a statistically significant difference in the 1th channel about the NRT threshold(P<0.05).Conclusion:Using Nucleus 24 Contour makes the surgery ~esaier than using Nucleus 24 M,minimizes the introcochlear trauma during insertion and reduces the current level producing electrical hearing.The Nucleus 24 Contour is a new,safe and effective implantation to the patients with profound sensorineural hearing loss .
