Abstract

Objectives: This study aimed to compare the audiological benefits of a non-implantable wearable option for a bone conduction (BC) implant mounted on an arch (SoundArc) to those of traditional BC hearing aids (HAs) mounted on eyeglasses (BCHAs) in patients with moderate to severe conductive or mixed hearing loss.

Methods: A preliminary cross-sectional observational prospective cohort study was conducted in the Tertiary Audiological Department, University Hospital. Fourteen adults with conductive or mixed hearing loss (PTA at 0.5-1-2-4 KHz = 67 ± 15 dB HL) who had been wearing conventional BCHAs mounted on eyeglasses for at least 3 years and had declined surgical implantation of a bone conduction hearing implant (BCHI) were included in the study. Unaided and aided pure-tone air conduction (AC) and bone conduction (BC) thresholds, as well as speech tests in quiet and noise, were recorded at baseline and in two different settings: with a BCHI mounted on SoundArc^® and with their own BCHAs mounted on eyeglasses using two couplers. Participants completed questionnaires in both conditions, including the International Inventory for Hearing Aids (IOI-HA), the Hearing Handicap Inventory for Adults/Elderly (HHIA/E), the Speech, Spatial, and Qualities of Hearing Scale (SSQ), a 10-point visual analog scale (VAS), and the Fatigue Impact Scale (FIS).

Results: A significant functional gain was observed in both settings (p = 0.0001). Better speech perception in quiet and noise was observed with SoundArc compared to conventional BCHAs on eyeglasses (improvements in word repetition scores in noise: +19.3 at SNR +10 dB, p = 0.002; +12.1 at SNR 0 dB, p = 0.006; and +11.4 at SNR -10 dB, p = 0.002). No significant differences were found in IOI-HA, FIS, and HHIA/E scores. However, significantly better SSQ scores were reported for SoundArc in all domains (p = 0.0038).

Conclusions: Although patients were accustomed to using BCHAs mounted on eyeglasses, the bone conduction wearable option of the BCHI (SoundArc) proved to be a viable alternative for adult patients with conductive or mixed hearing loss who are unable or unwilling to undergo BCHI surgery.

骨传导助听器植入的非手术佩戴式选择：与安装在眼镜上的传统骨导助听器的比较研究。

研究目的本研究旨在比较安装在拱门（SoundArc）上的骨传导（BC）非植入式可佩戴助听器（HAs）与安装在眼镜（BCHAs）上的传统BC助听器（HAs）对中重度传导性或混合性听力损失患者的听力益处：在大学医院三级听力科进行了一项初步的横断面观察性前瞻性队列研究。研究共纳入了 14 名患有传导性或混合性听力损失（0.5-1-2-4 KHz 时的 PTA = 67 ± 15 dB HL）的成年人，他们已佩戴安装在眼镜上的传统 BCHAs 至少 3 年，并拒绝手术植入骨导听力植入体 (BCHI)。研究人员在基线和两种不同环境下记录了无助和有助纯音气导（AC）和骨导（BC）阈值，以及安静和噪音环境下的言语测试：使用安装在 SoundArc® 上的 BCHI 和使用两个耦合器安装在眼镜上的 BCHA。在这两种情况下，受试者都填写了问卷，包括国际助听器量表（IOI-HA）、成人/老年人听力障碍量表（HHIA/E）、言语、空间和听力质量量表（SSQ）、10 点视觉模拟量表（VAS）和疲劳影响量表（FIS）：结果：在两种环境下均观察到明显的功能增益（p = 0.0001）。与佩戴眼镜的传统 BCHA 相比，SoundArc 在安静和噪音环境下的语音感知能力更强（噪音环境下的单词重复得分提高了 19.3 分，信噪比提高了 +1.5：SNR +10 dB 时为 +19.3，p = 0.002；SNR 0 dB 时为 +12.1，p = 0.006；SNR -10 dB 时为 +11.4，p = 0.002）。在 IOI-HA、FIS 和 HHIA/E 分数上没有发现明显差异。然而，SoundArc 在所有领域的 SSQ 分数都明显更高（p = 0.0038）：尽管患者习惯于使用安装在眼镜上的 BCHA，但事实证明，对于无法或不愿接受 BCHI 手术的传导性或混合性听力损失的成年患者来说，骨传导可穿戴式 BCHI（SoundArc）是一种可行的替代方案。
