Abstract

Introduction

Although the Baha 5SP has been commercially available for six years, very few studies have been performed on the device's efficacy. The current study aims to evaluate the characteristics and audiological results in patients with severe-to-profound mixed hearing loss fitted with this superpower sound processor.

Methods

This retrospective evaluation was conducted at a tertiary referral centre where a series of 82 adult patients with severe-to-profound mixed hearing loss were implanted with a percutaneous bone-anchored hearing system and fitted with a superpower sound processor between 2016 and 2019. Patients with incomplete or unreliable audiological data (n = 24) were excluded, resulting in 58 data sets for analysis. The main outcome measures were unaided and aided pure-tone thresholds and aided free-field speech perception in quiet.

Results

The median unaided air conduction (AC) threshold averaged across 0.5, 1 and 2 kHz (PTA0.5–2kHz) of all patients was 75 dB hearing loss (HL); the median unaided AC averaged across 1, 2 and 4 kHz (PTA1–4kHz) was 84 dB HL. For bone conduction and direct bone conduction, the median PTA0.5–2kHz was 52 and 47 dB HL, respectively. With the superpower device, the median free-field speech reception threshold was 54 dB sound pressure level (SPL), and the median speech perception score at 65 dB SPL was 80%.

Conclusions

At least 75% of the patients reached a maximum phoneme score of 70%. For patients with lower scores, the superpower device still provides a substantial hearing benefit. This makes the superpower device particularly suitable for patients with severe-to-profound mixed hearing loss with a contraindication for conventional hearing aids and/or cochlear implants.

对超强骨定位听力系统及其用户的评估:回顾性研究
介绍:尽管Baha 5SP已上市六年,但有关该设备功效的研究却寥寥无几。本研究旨在评估安装了这种超强声音处理器的重度至永久性混合性听力损失患者的特征和听力结果:这项回顾性评估是在一家三级转诊中心进行的,该中心在 2016 年至 2019 年期间为 82 名重度至永久性混合性听力损失的成年患者植入了经皮骨锚定听力系统,并安装了超强声音处理器。排除了听力数据不完整或不可靠的患者(n = 24),最终得出 58 组数据用于分析。主要结果指标为无助和有助纯音阈值以及安静时的有助自由声场言语感知:所有患者在 0.5、1 和 2 kHz(PTA0.5-2kHz)范围内的平均无助气导(AC)阈值中值为 75 dB 听力损失(HL);在 1、2 和 4 kHz(PTA1-4kHz)范围内的平均无助 AC 中值为 84 dB HL。骨导和直接骨导的 PTA0.5-2kHz 中值分别为 52 和 47 dB HL。使用超强设备时,自由声场言语接收阈值的中位数为 54 dB 声压级(SPL),65 dB SPL 时言语感知分数的中位数为 80%:结论:至少有 75% 的患者达到了 70% 的最高音素分数。对于得分较低的患者,超强听力设备仍能为他们带来巨大的听力益处。因此,超级助听器特别适合重度至永久性混合性听力损失且有传统助听器和/或人工耳蜗植入禁忌症的患者。

期刊介绍: Clinical Otolaryngology is a bimonthly journal devoted to clinically-oriented research papers of the highest scientific standards dealing with: current otorhinolaryngological practice audiology, otology, balance, rhinology, larynx, voice and paediatric ORL head and neck oncology head and neck plastic and reconstructive surgery continuing medical education and ORL training The emphasis is on high quality new work in the clinical field and on fresh, original research. Each issue begins with an editorial expressing the personal opinions of an individual with a particular knowledge of a chosen subject. The main body of each issue is then devoted to original papers carrying important results for those working in the field. In addition, topical review articles are published discussing a particular subject in depth, including not only the opinions of the author but also any controversies surrounding the subject. • Negative/null results In order for research to advance, negative results, which often make a valuable contribution to the field, should be published. However, articles containing negative or null results are frequently not considered for publication or rejected by journals. We welcome papers of this kind, where appropriate and valid power calculations are included that give confidence that a negative result can be relied upon.
