Overview Introduction: Bonebridge is a direct bone conduction hearing implantable system. The aim of the work is to present pilot results of rehabilitation of single sided deafness using this system. Material and methods: Analysis of three patients with single-sideded deafness, who underwent BB implantation in 2018 at the Department of Otorhinolaryngology and Head and Neck Surgery of St. Anna Hospital in Brno. Evaluation parameters: Bern Benefi t in Single-Sided Deafness Questionnaire, experimental examination of directional hearing and hearing in noise test. Results: Questionnaire: Within the visual analog scale in the range of –5 to +5 points, the average rating was + 2.4 points, so listening was rated as easier with Bonebridge than without hearing aids. The ability to locate the sound source was evaluated by 4 and 0–1 points in one and two respondents, respectively. Examination of spatial hearing: without hearing aid, the ability to locate the sound source was signifi cantly impaired in all the examined. With Bonebridge, with a tolerated deviation of 45°, the success rate of sound source localization was 75–100% in the range of 0–360° in the horizontal plane. Hearing in noise test: the greatest improvement in intelligibility (by 30–100%) was achieved with Bonebridge at SNR –5 dB. Conclusion: Bonebridge is not able to restore binaural hearing in patients with single sided deafness, it is a pseudo-binaural correction. Like other implantable bone conduction systems, Bonebridge is benefi tial for patients with single sided deafness in a variety of listening situations. Using experimental audiological tests, the contribution of Bonebridge to understanding sentences in acoustic noise and improving the ability to locate the sound source was found. However, validation of the results would require a larger number of probands. Keywords: single-sided deafness – BAHD – Bonebridge – bone conduction hearing implant – hearing in noise – directional hearing test

Background: While hearing aids for a contralateral routing of signals (CROS-HA) and bone conduction devices have been the traditional treatment for single-sided deafness (SSD) and asymmetric hearing loss (AHL), in recent years, cochlear implants (CIs) have increasingly become a viable treatment choice, particularly in countries where regulatory approval and reimbursement schemes are in place. Part of the reason for this shift is that the CI is the only device capable of restoring bilateral input to the auditory system and hence of possibly reinstating binaural hearing. Although several studies have independently shown that the CI is a safe and effective treatment for SSD and AHL, clinical outcome measures in those studies and across CI centers vary greatly. Only with a consistent use of defined and agreed-upon outcome measures across centers can high-level evidence be generated to assess the safety and efficacy of CIs and alternative treatments in recipients with SSD and AHL. Methods: This paper presents a comparative study design and minimum outcome measures for the assessment of current treatment options in patients with SSD/AHL. The protocol was developed, discussed, and eventually agreed upon by expert panels that convened at the 2015 APSCI conference in Beijing, China, and at the CI 2016 conference in Toronto, Canada. Results: A longitudinal study design comparing CROS-HA, BCD, and CI treatments is proposed. The recommended outcome measures include (1) speech in noise testing, using the same set of 3 spatial configurations to compare binaural benefits such as summation, squelch, and head shadow across devices; (2) localization testing, using stimuli that rove in both level and spectral content; (3) questionnaires to collect quality of life measures and the frequency of device use; and (4) questionnaires for assessing the impact of tinnitus before and after treatment, if applicable. Conclusion: A protocol for the assessment of treatment options and outcomes in recipients with SSD and AHL is presented. The proposed set of minimum outcome measures aims at harmonizing assessment methods across centers and thus at generating a growing body of high-level evidence for those treatment options.

As the technology advances and bone conduction implant (BCI) use increases, implantable bone conduction hearing aids are regarded as a treatment method for single-sided deafness (SSD) and their efficacy on SSD must be discussed. Therefore, we organized the problems of SSD and types of implantable bone conduction hearing aids and explained their effectiveness in the treatment of SSD in terms of changes in 1) speech recognition in a noisy environment, 2) sound localization, 3) subjective satisfaction as assessed by questionnaire, and 4) tinnitus. Although bone conduction hearing aids do not significantly improve localization ability in SSD, they increase the ability to listen under noise, increasing subjective satisfaction. Tinnitus improvement was also reported. The active forms of BCI like MED-EL BONEBRIDGE®2 and Cochlear Osia®2 have been developed well. Based on these technological developments and effects, bone conduction hearing aids would be a good option for treatment option of SSD.

Objectives. To analyze the clinical application of SoundBite bone conduction hearing aids by assessing the improvement of speech recognition and the scores of the benefit scale questionnaire for patients with single-sided deafness (SSD). Design. Nine patients aged 24 to 61 years with SSD for more than 3 months were enrolled in this study. The patients could understand and repeat Mandarin and have good compliance with the study. The measurements were evaluated before and after one month of wearing hearing aids using the pure tone audiometry threshold, speech recognition in quiet and in noise, and the Glasgow Benefit Inventory (GBI) benefit scale score. Results. Pure tone audiometry results showed that the average hearing threshold of good ears and bad ears was 11.4±2.6 dB HL and 89.9±6.4 dB HL, respectively. The average hearing threshold of bad ears after wearing hearing aids was 23.5±9.0 dB HL. Statistical analysis showed that the hearing improvement for the bad ears after wearing hearing aids was significant. The speech audiometry results showed that the disyllable word recognition score of the bad ears in quiet increased significantly at 50 dB SPL by 40±12 percentage points and at 65 dB SPL by 71±15 percentage points. As for the speech recognition in noise, when the signal sound came from the bad ear side and the noise from the good ear side (SSSDNAH), the speech recognition score (SRS) significantly increased by 17±6 and 9±4 at a signal-to-noise ratio (SNR) of -2 dB and -5 dB, respectively, after wearing the hearing aids. When the signal sound came from the front of the patient and the noise from the bad ear side (S0NSSD), the SRS scores were reduced by 5±5 and 7±5 percentage points at SNR equal to -2 dB and -5 dB, which was significantly different from that before wearing the hearing aids. When the signal and noise both came from the front of the patients (S0N0), the SRS was not significantly increased by 5±4 percentage points at SNR equal to -2 dB compared to before wearing hearing aids. However, the SRS was significantly increased by 5±2 percentage points at SNR equal to -5 dB compared to before wearing hearing aids. The average total GBI score was 31±12 for the nine patients, with an average score of 32±10, 31±8, and 30±7 for general conditions, social support, and physical health, respectively. The results of the questionnaires showed that patients’ quality of life was improved after wearing SoundBite bone conduction hearing aids. Conclusions. SoundBite bone conduction hearing aids are a good choice for patients with SSD, as it could improve the speech recognition ability of patients both in a quiet and noisy environment and improves the quality of life after wearing hearing aids.

Bone conduction is an efficient pathway of sound transmission which can be harnessed to provide hearing amplification. Bone conduction hearing devices may be indicated when ear canal pathology precludes the use of a conventional hearing aid, as well as in cases of single-sided deafness. Several different technologies exist which transmit sound via bone conduction. Here, we will review the physiology of bone conduction, the indications for bone conduction amplification, and the specifics of currently available devices.

Introduction: Nowadays, there are many options to treat hearing-impaired patients: tympanoplastic surgery, hearing aids and a wide range of implantable devices. Objective: The aim of this study is to present the mid-term audiological and quality of life benefits after the implantation of the Osia®, a new active piezoelectric bone conduction hearing implant. Material and methods: The state of the tissues in implanted area, as well as audiological and quality of life results were analyzed six, nine and twelve months after implantation in a group of four adult patients with bilateral mixed hearing loss. Results: In all the cases, no postoperative complications were found. One year after surgery the mean audiological gain in FF PTA4 (pure tone average for 0.5, 1, 2, and 4 kHz) was 52.2±3.5 dB in comparison to the unaided situation, the mean speech understanding with Osia® in quiet was 90±8.2% for 50dB SPL, 98.8±2.5% for 65dB SPL and 100±0% for 80dB SPL, and mean speech understanding with Osia® in noise was 37.5%±23.6 for 50dB SPL, 93.8±4.8% for 65dB SPL and 98.8±2.5% for 80dB SPL. There was also an evident improvement in the quality of hearing as well as in the quality of life, measured by the APHAB (Abbreviated Profile of Hearing Aid Benefit) and the SSQ (Speech, Spatial and Qualities of Hearing Scale). Conclusions: The Osia® is an effective treatment option for patients with bilateral mixed hearing loss. The mid-term audiological and quality of life results are excellent, but further observations including bigger groups of patients and a longer follow-up are required.
