There are two types of speech processors used in CI devices: behind-the-ear (BTE) and off-the-ear (OTE).
This study aimed to investigate the characteristics of patients and revision cases in relation to the type of speech processors.
A retrospective review of 452 ears that underwent CI was performed.
Children with severe inner ear anomalies (91.7%) more frequently preferred BTE speech processors than those without severe inner ear anomalies ( = .000). The magnet strength used in OTE speech processor users was significantly higher than in BTE speech processor users ( = .002). In cochlear implantees who underwent surgery before 12 months of age, the magnet strength in the revision group was greater than in the non-revision group ( = .025).
Overall, our findings suggest factors to consider when choosing the type of speech processor and modifying the magnet strength of the implant device. The choice between BTE and OTE speech processors led to different required magnet strengths, contributing to the occurrence of skin flap inflammation.
人工耳蜗（CI）设备中使用两种类型的言语处理器：耳背式（BTE）和耳上式（OTE）。
本研究旨在调查与言语处理器类型相关的患者特征和翻修病例情况。
对452例接受人工耳蜗植入的耳进行回顾性研究。
患有严重内耳异常的儿童（91.7%）比无严重内耳异常的儿童更频繁地选择耳背式言语处理器（P = 0.000）。耳上式言语处理器使用者使用的磁铁强度显著高于耳背式言语处理器使用者（P = 0.002）。在12个月龄之前接受手术的人工耳蜗植入者中，翻修组的磁铁强度大于未翻修组（P = 0.025）。
总体而言，我们的研究结果提示了选择言语处理器类型和调整植入设备磁铁强度时需考虑的因素。耳背式和耳上式言语处理器的选择导致所需磁铁强度不同，这可能导致皮瓣炎症的发生。
