OBJECTIVE
To describe a simple technique for pediatric cochlear implant receiver-stimulators (R/S) fixation and long term results with it.
METHODS
Clinical sample include thirty-two children with severe-to-profound or profound hearing loss candidate for cochlear implantation. Low-profile devices were used (Med El Concerto and Nucleus CI512). The R/S was housed into a tight subperiosteal pocket carefully dissected behind the mastoidectomy. The pocket was closed with a single periosteal to bone suture around the posterior edge of mastoidectomy. No skull drilling was required for housing the device.
RESULTS
No intraoperative complications have been observed. 20% of operating time was saved. No migration of R/S over time was apparent at follow up.
CONCLUSIONS
The back-pocket technique seems effective in retaining the CI package and in optimizing surgical time and safety in pediatric cochlear implantation. It seems particularly suitable with new generation low profile CI devices.
目的
描述一种用于儿童人工耳蜗植入体接收器-刺激器（R/S）固定的简单技术及其长期效果。
方法
临床样本包括32名重度至极重度或极重度听力损失且适合人工耳蜗植入的儿童。使用了低轮廓装置（美迪康协奏曲和科利耳CI512）。将R/S置于乳突切除术后仔细解剖出的紧密骨膜下袋中。用一根骨膜与骨的缝线围绕乳突切除术的后缘封闭该袋。放置该装置无需颅骨钻孔。
结果
未观察到术中并发症。节省了20%的手术时间。随访时未发现R/S随时间迁移。
结论
后袋技术在儿童人工耳蜗植入中似乎能有效固定CI组件，并优化手术时间和安全性。它似乎特别适用于新一代低轮廓CI装置。
