| Abstract (English): | Cochlear implant (CI) surgery is a safe surgical technique, although some patients require revision CI surgery. This study investigated the cause and underlying reason of revision CI surgery as well as hearing outcomes in a single institution. This retrospective study evaluated patients who underwent CI surgery between April 2006 to March 2022 (n = 351). Sex, aetiology of hearing loss (HL), age and period from initial CI surgery to reimplantation, cause of revision, and related factors were examined. Twelve patients (8 males, 4 females) received CI reimplantation. The revision surgery rate was 2.59% (3.15% children, 1.69% adults); the period from initial surgery to reoperation was 8.60 ± 6.56 years for 9 children with congenital HL and 15.27 ± 5.72 years for 3 adults with progressive HL. Device failure was the most common cause (n = 8), followed by infections (n = 2), advanced facial irritation symptoms (n = 1), and electrode slip-out (n = 1). Mean preoperative and postoperative CI thresholds were 44.0 ± 9.46 dBnHL and 39.19 ± 8.89 dBnHL (p <.068), respectively. Caregiver education, surgical technique advances, flap design, and extensive antibiotic use may decrease the revision surgery rate. The lack of post-revision deterioration of the hearing threshold contributed to well-being in patients with CI. [ABSTRACT FROM AUTHOR] |
| Abstract (Chinese): | 背景: 人工耳蜗植入 (CI) 手术是一种安全的外科技术, 尽管有些患者需要修复 CI 手术。 目的: 本研究调查了 CI 修复手术的原因和导因, 并且探讨了单一医院的听力结果。 患者和方法: 这项回顾性研究评估了在2006 年 4 月至 2022 年 3 月接受 CI 手术的患者(n = 351)。对 性别、听力损失 (HL) 病因、从首次CI到再植的年龄和时长、修复原因以及相关因素进行了查检。 结果: 12 名患者(8 名男性, 4 名女性)接受了 CI 再植术。 修复手术率为2.59%(儿童3.15%, 成人1.69%)； 9 名先天性 HL儿童的首次手术至再次手术的间隔时长为8.60 ± 6.56年, 3 名进行性 HL 成人为 15.27 ± 5.72 岁。 设备故障是最常见的原因 (n = 8), 其次是感染 (n = 2)、晚期面部刺激症状(n = 1) 和电极滑出 (n = 1)。 术前和术后平均 CI 阈值分别为 44.0 ± 9.46 dBnHL 和 39.19 ± 8.89 dBnHL (p<.068)。 结论和意义: 护理人员教育、手术技术提升、皮瓣设计和广泛使用抗生素可能会降低修复手术率。 修复后听力阈值不发生退化, 有助于 CI 患者的利益。 [ABSTRACT FROM AUTHOR] |
