Treatment options for congenital aural atresia (CAA) include canaloplasty and implantation of an osseointegrated bone conduction device (OBCD). Few studies have compared hearing outcomes in these two treatment methods.
Hearing outcomes and revision surgery rates were compared in CAA patients managed by canaloplasty and surgically implanted OBCD.
This study retrospectively analyzed 36 patients with CAA at a single institution. The same surgeon performed canaloplasty on 23 patients. Hearing outcomes before surgery as well as 3 and 6 months after surgery were compared to those of 13 patients with OBCD implantation.
Postoperative hearing outcomes were better in the OBCD group, but the difference was not statistically significant. At 6-month follow-up, the hearing thresholds in the canaloplasty and OBCD group were 38.6 ± 21.4 and 31.9 ± 6.4 dB, respectively. The success rates 6 months after surgery were 75.0% in the canaloplasty group and 100% in the OBCD group. Two out of 23 patients in the canaloplasty group and 7 out of 13 patients in the OBCD group underwent revision surgery.
In terms of hearing, the outcome was better with the OBCD compared to canaloplasty. Canaloplasty may be an alternative option in patients who refuse OBCD implantation.
先天性外中耳畸形（CAA）的治疗选择包括耳道成形术和植入骨整合式骨导装置（OBCD）。很少有研究比较这两种治疗方法的听力结果。
比较 CAA 患者行耳道成形术和手术植入 OBCD 的听力结果和翻修手术率。
本研究回顾性分析了单中心的 36 例 CAA 患者。同一位外科医生为 23 例患者施行耳道成形术。比较手术前以及手术后 3 个月和 6 个月的听力结果与 13 例接受 OBCD 植入术患者的听力结果。
OBCD 组的术后听力结果更好，但差异无统计学意义。在 6 个月随访时，耳道成形术和 OBCD 组的听力阈值分别为 38.6±21.4dB 和 31.9±6.4dB。术后 6 个月的成功率分别为耳道成形术组的 75.0%和 OBCD 组的 100%。在耳道成形术组中有 2 例患者和 OBCD 组中有 7 例患者需要进行翻修手术。
就听力而言，OBCD 的结果优于耳道成形术。对于拒绝植入 OBCD 的患者，耳道成形术可能是一种替代选择。
