Comparison of the auditory and subjective capabilities of 2 implantable bone conduction devices BAHA Divino sound processor (Divino) and the BAHA BP100 sound processor (BP100) using a daily alternating method.
Open prospective comparative trial.
Tertiary referral otology and neurotology center.
Ten patients with single-sided deafness (SSD) using a Divino for more than 1 year.
The patients with SSD changed to the BP100 for 1 week, and then underwent an evaluation period of 18 days switching between BP100 and Divino on a daily alternating basis. On a scale from 0 to 10, patients rated their quality of hearing daily with both devices concerning overall satisfaction, clearness of sound, and effort of listening in background noise. For the total duration of the trial, the spatial hearing questionnaire (SHQ) and the abbreviated profile of hearing aid benefit (APHAB) were administered. In the unaided condition and with Divino at baseline and aided with BP100 after the evaluation period, adaptive speech in quiet and in noise testing was performed with speech and noise coming from different azimuth angles.
Subjective rating in a diary, APHAB, SHQ, and aided speech in quiet and speech in noise.
The diary shows significant improvement on all subscales with BP100 in comparison with Divino. These differences did not change significantly during 18 days. On the APHAB, listening in background noise and in reverberant conditions was rated significantly better with the BP100. The SHQ shows a significant difference between both devices on all subscales except for source localization and speech understanding in quiet. Speech audiometry showed a significant head shadow benefit with both implantable bone conduction devices (median [Q1, Q3]: Divino = 2.67 dB [0.33, 1.51], BP100 = 2.83 dB [4.08, 3.83]). There was no significant difference found between both devices.
Both the Divino and the BP100 reduce the handicap experienced by patients with SSD. Subjective assessment using a daily alternating method shows higher overall hearing capabilities with BP100. Results of the questionnaires are similar. Speech audiometry in noise does not reveal a statistically significant difference between both devices. A daily alternating method can provide useful information for both the patient and the audiologist because objective measurements do not show any statistically significant differences between patients. In our opinion, daily alternation of devices is a useful method to compare different devices.
使用每日交替法比较 2 种植入式骨导设备 BAHA Divino 声音处理器（Divino）和 BAHA BP100 声音处理器（BP100）的听觉和主观能力。
开放前瞻性对照试验。
三级转诊耳科学和神经耳科学中心。
10 名使用 Divino 超过 1 年的单侧聋（SSD）患者。
SSD 患者改用 BP100 1 周，然后进行 18 天的评估期，每天在 BP100 和 Divino 之间交替使用。患者每天使用两种设备根据总体满意度、声音清晰度和在背景噪音中聆听的努力程度对听力质量进行评分，分值为 0 到 10 分。在整个试验期间，还进行了空间听力问卷（SHQ）和听力辅助受益简短问卷（APHAB）。在未佩戴设备、Divino 基线和评估期后佩戴 BP100 的情况下，对来自不同方位角的言语和噪声进行安静和噪声环境下的适应性言语测试。
日记中的主观评分、APHAB、SHQ、安静时和噪声环境下的辅助言语。
与 Divino 相比，BP100 在所有子量表上的评分均显著提高。这些差异在 18 天内没有显著变化。在 APHAB 中，在背景噪声和混响环境下的听力被评为 BP100 更好。SHQ 显示在所有子量表上两种设备之间存在显著差异，除声源定位和安静环境下的言语理解外。言语测听显示两种植入式骨导设备均有显著的头部阴影受益（中位数[Q1，Q3]：Divino = 2.67dB[0.33，1.51]，BP100 = 2.83dB[4.08，3.83]）。两种设备之间没有发现显著差异。
Divino 和 BP100 均减轻了 SSD 患者的残疾程度。使用每日交替法进行的主观评估显示 BP100 具有更高的整体听力能力。问卷调查结果相似。噪声环境下的言语测听未显示两种设备之间存在统计学上的显著差异。每日交替法可以为患者和听力学家提供有用的信息，因为客观测量未显示患者之间存在任何统计学上的显著差异。在我们看来，设备的日常交替是比较不同设备的有用方法。
