This study aimed to determine the effect of the subperiosteal tight pocket technique versus the bone recess with suture fixation technique on the revision cochlear implantation rate and complications.
This retrospective study included 1514 patients who underwent cochlear implantation by 2 senior surgeons between October 2002 and January 2016. Revision cases were identified and analysed.
In all, 52 patients (3.34 per cent) underwent revision cochlear implantation. The revision rate was 7.18 per cent in the subperiosteal tight pocket group versus 2.37 per cent in the bone recess with suture fixation group (p < 0.001). Device failure was the most common reason for revision surgery in both groups. There was a significant difference in the device failure rate between the bone recess with suture fixation group (2.11 per cent) and subperiosteal tight pocket group (6.88 per cent) (p < 0.001).
Accurate fixation of the cochlear implant receiver/stimulator is crucial for successful cochlear implantation. As the bone recess with suture fixation technique is associated with a lower revision rate and a similar complication rate as the subperiosteal tight pocket technique, it should be the preferred fixation technique for cochlear implantation.
本研究旨在确定骨膜下紧密口袋技术与骨槽缝合法对人工耳蜗植入翻修率及并发症的影响。
这项回顾性研究纳入了2002年10月至2016年1月间由2名资深外科医生实施人工耳蜗植入手术的1514例患者。对翻修病例进行识别和分析。
共有52例患者（3.34%）接受了人工耳蜗植入翻修手术。骨膜下紧密口袋组的翻修率为7.18%，而骨槽缝合法组为2.37%（p<0.001）。装置故障是两组翻修手术最常见的原因。骨槽缝合法组（2.11%）与骨膜下紧密口袋组（6.88%）的装置故障率存在显著差异（p<0.001）。
人工耳蜗接收器/刺激器的精确固定对人工耳蜗植入成功至关重要。由于骨槽缝合法与骨膜下紧密口袋技术相比翻修率更低且并发症发生率相似，因此它应是人工耳蜗植入的首选固定技术。
