Over the last ten years about 850 cochlear implant operations were performed at the ENT department of Hannover Medizinische Hochschule. In most cases, intracochlear nucleus implants were used. For about two years the intracochlear Clarion device has also been used in 150 adults and children. For several years we have used ionomeric cement (lonocap, supplied by lonos, Seefeld/Germany) to fix the electrode array in the region of the posterior wall and the facial recess. Previously, the implant package was fixed by ionomeric cement. To evaluate the outcome of cement application, we conducted a prospective study of our implant patients during the period from 1991 to 1993. During regular reexamination over a period of two years postoperatively in 244 patients (122 male and 122 female patients, average age 17.6 years), we did not observe any complication related to the cement. Nearly all revision cases (n = 8) showed a stable contact between electrode array, bone, and cement. With increasing experience, we reduced the cement application and fixed the package with vicryl sutures in a precisely drilled bony bed. Contact of the cement with neural and cerebral structures should be avoided. In our experience ionomeric cement is a helpful tool in cochlear implant surgery with long-term stability and no rejection reactions.
在过去十年中，汉诺威医学院耳鼻喉科进行了约850例人工耳蜗植入手术。多数情况下使用的是蜗神经核植入物。在大约两年的时间里，150名成人和儿童还使用了蜗内Clarion装置。数年来，我们一直使用离聚物粘固粉（Lonocap，由德国锡费尔德的Lonos公司供应）将电极阵列固定在后壁和面隐窝区域。以前，植入组件是用离聚物粘固粉固定的。为了评估粘固粉的应用效果，我们在1991年至1993年期间对我们的植入患者进行了一项前瞻性研究。在对244例患者（122例男性和122例女性患者，平均年龄17.6岁）术后两年的定期复查期间，我们未观察到与粘固粉相关的任何并发症。几乎所有的翻修病例（n = 8）都显示电极阵列、骨和粘固粉之间接触稳定。随着经验的增加，我们减少了粘固粉的用量，并在精确钻孔的骨床中用维克牢尼龙缝线固定植入组件。应避免粘固粉与神经和脑结构接触。根据我们的经验，离聚物粘固粉是人工耳蜗植入手术中的一种有用工具，具有长期稳定性且无排斥反应。
