Abstract
OBJECTIVES This study aimed to investigate the effects of an adhesive bone conduction device (aBCD) in children with congenital single-sided deafness (SSD). Specifically, we examined whether the aBCD elicits improvement in the speech perception ability of children with congenital SSD and whether using this device would adversely affect the horizontal localisation abilities of these children. METHODS Thirteen school-aged children with SSD and seven children with Normal Hearing (NH) were included in this study. Speech perception in noise was measured using the Mandarin Speech Test Materials and sound localisation performance was evaluated using broadband noise stimuli (0.5-20 kHz), randomly played from seven loudspeakers at different stimulus levels (65-, 70-, and 75-dB SPL). RESULTS All children with SSD showed inferior speech perception and sound localisation performance compared with children with NH. The aBCD use remarkably improved the speech perception abilities of these children under quiet and noise conditions; however, their sound localisation abilities neither improved nor deteriorated. CONCLUSION This study reveals the effectiveness and safety of a non-surgical aBCD in paediatric patients with SSD. Our results provide a theoretical basis for early hearing intervention with an aBCD in children with congenital SSD who are temporarily unable to undergo ear surgery. LEVEL OF EVIDENCE Level 3.

Abstract
The incidence of single-sided deafness(SSD) is increasing year by year. Due to the hearing defects of one ear, the ability of sound localization, speech recognition in noise, and quality of life of patients with single-sided deafness will be affected to varying degrees. This article reviews the intervention effects of different types of bone conduction hearing aids in patients with single-sided deafness and asymmetric hearing loss, and the differences of intervention effects between bone conduction hearing aids, contralateral routing of signal(CROS) aids, and cochlea implant(CI), to provide a reference for the auditory intervention and clinical treatment of single-sided deafness and asymmetric hearing loss.

Abstract
Objectives The young population requires early rehabilitation of their hearing loss for normal cognitive, auditive hence social development. All of which, in turn, may have an impact on quality of life (QoL). This study aims to evaluate QoL between two different bone conduction (BC) hearing devices: a noninvasive adhesive hearing aid (Adhear [ADH]) vs. an active transcutaneous implant (Bonebridge [BB]). Methods This study composed of 12 BB and 15 ADH users. Pure tone as well as speech in noise and quiet measurements were evaluated and compared to the Assessment in QoL questionnaire (AQoL-6d). Results Freefield results showed significant improvements for both devices compared to the unaided condition (p < .0001). Emphasis needs to be drawn on the different unaided level of conductive hearing loss as well as the indication range for both evaluated device groups: the ADH subjects exhibited a mean BC value of 9.50 ± 7.96 dB HL (the indication range up to 25 dB) and the BB subjects a mean of 23.33 ± 25.66 dB HL (the indication range up to 45 dB). Speech perception in quiet and in noise was significantly improved (p < .05; p < .001, respectively). QoL was significantly improved for both treatments (p < .05) but was not different among the devices, and the values were similar to their normal hearing, age, and sex-matched control group. High correlations were found between QoL utility scores and improved PTA4 in the aided condition (r 2 = .8839 and .7810 for BB and ADH, respectively). Conclusion Our results show that both devices offer significant beneficial audiological rehabilitations with significantly increased QoL. However, the underlying condition and the unaided degree of hearing loss, hence the required higher stimulation must be the deciding factor when opting for a hearing device, and this should be independent of age. Level of evidence 2c.

Abstract
OBJECTIVE To measure audiologic outcomes and self-assessed satisfaction with the Ponto system in a group of patients who had severe to profound and mixed hearing loss. STUDY DESIGN Retrospective case review. SETTING Tertiary referral center. PATIENTS Sixteen patients aged 21 to 74 years with severe-to-profound and mixed hearing loss (bone conduction thresholds, ≥45 dB HL). INTERVENTIONS Ponto implant surgery. MAIN OUTCOME MEASURES Pure-tone audiometry, free-field hearing thresholds, effective gain, word recognition score in quiet, and speech reception threshold (SRT) in noise were assessed. Patient-reported outcomes were collected using the Clinical Global Impression Scale, Glasgow Benefit Inventory, and Abbreviated Profile of Hearing Aid Benefit. Information concerning any medical complications was also gathered. RESULTS Both word recognition score and SRT were significantly better after 12 months compared with before surgery. At normal speech level (65 dB SPL), 12 of 16 users had speech discrimination ≥70%. However, at the 12-month follow-up, the average effective gain was -6.2 dB. In general, the self-report outcomes showed good satisfaction in most patients. Postoperatively, skin complications were noted in six patients, of whom two underwent reoperation. All patients were still using the Ponto after an average observation time of 2.7 years. CONCLUSION Although skin complications were not uncommon, the Ponto system seems to be an effective method of improving hearing performance and provides subjective satisfaction in real-life situations in patients with severe-to-profound and mixed hearing loss. However, considering the significantly increased bone conduction thresholds and the risk of their further deterioration, long-term follow-up is still needed.

Abstract
PURPOSE (1) To assess the effectiveness and safety of a bone-conduction implant, the Bonebridge BCI 602, in adults with conductive or mixed hearing loss. (2) To investigate whether the Bonebridge BCI 602 is at least as effective as the Bonebridge BCI 601 in such patients. METHODS The study group included 42 adults who had either conductive or mixed hearing loss. All patients underwent Bonebridge BCI 602 implant surgery. Before and after implantation, pure-tone audiometry, speech recognition tests (in quiet and noise), and free-field audiometry were performed. Word recognition scores were evaluated using the Polish Monosyllabic Word Test. Speech reception thresholds in noise were assessed using the Polish Sentence Matrix Test. Subjective assessment of benefits was done using the APHAB (Abbreviated Profile of Hearing Aid Benefit) questionnaire. RESULTS The APHAB questionnaire showed that difficulties in hearing decreased after BCI 602 implantation. Both word recognition in quiet and speech reception threshold in noise were significantly better after BCI 602 implantation and remained stable for at least 12 months. A significant advantage of the device is a reduced time for surgery while maintaining safety. In this study, the mean time for BCI 602 implantation was 28.3 min ± 9.4. CONCLUSIONS The second-generation Bonebridge BCI 602 implant is an effective hearing rehabilitation device for patients with conductive or mixed hearing loss. Patient satisfaction and audiological results confirm its efficacy and safety. Its new shape and dimensions allow it to be used in patients previously excluded due to insufficient or difficult anatomical conditions. The new BCI 602 implant is as effective as its predecessor, the BCI 601.

[PMID: 34945210 PMCID: PMC8707547 DOI: 10.3390/jcm10245916] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/19/2021] [Revised: 12/08/2021] [Accepted: 12/10/2021] [Indexed: 11/24/2022] Open
Abstract
Background: the Bonebridge hearing implant is an active transcutaneous bone conduction implant suitable for various types of hearing loss. It was first launched in 2012 as the BCI 601, with a newer internal part (BCI 602) released in 2019. With the new size and shape, the BCI 602 can be used in patients previously excluded due to insufficient anatomical conditions, especially in patients with congenital defects of the outer and middle ear. Objectives: the purpose of this study is to evaluate the objective and subjective benefits of the new Bonebridge BCI 602 in children who have hearing impairment due to conductive or mixed hearing loss. Safety and effectiveness of the device was assessed. Methods: the study group included 22 children aged 8–18 years (mean age 14.7 years) who had either conductive or mixed hearing loss. All patients were implanted unilaterally with the new Bonebridge BCI 602 implant. Pure tone audiometry, speech recognition tests (in quiet and noise), and free-field audiometry were performed before and after implantation. Word recognition scores were evaluated using the Demenko and Pruszewicz Polish Monosyllabic Word Test, and speech reception thresholds in noise were assessed using the Polish Sentence Matrix Test. The subjective assessment of benefits was carried outusing the APHAB (Abbreviated Profile of Hearing Aid Benefit) questionnaire. Results: after implantation of the Bonebridge BCI 602 all patients showed a statistically significant improvement in hearing and speech understanding. The mean word recognition score (WRS) changed from 12.1% before implantation to 87.3% after 6 months. Mean speech reception threshold (SRT) before implantation was +4.79 dB SNR and improved to −1.29 dB SNR after 6 months. All patients showed stable postoperative results. The APHAB questionnaire showed that difficulties in hearing decreased after implantation, with a statistically significant improvement in global score. Pre-operative scores (M = 35.7) were significantly worse than post-operative scores at 6 months (M = 25.7). Conclusions: the present study confirms that the Bonebridge BCI 602 is an innovative and effective solution, especially for patients with conductive and mixed hearing loss due to anatomical ear defects. The Bonebridge BCI 602 system provides valuable and stable audiological and surgical benefits. Subjective assessment also confirms the effectiveness of the BCI 602. The BCI 602 offers the same amplification as the BCI601, but with a smaller size. The smaller dimensions make it an effective treatment option for a wider group of patients, especially children with congenital defects of the outer and middle ear.

Abstract
PURPOSE This study aimed to evaluate the audiological benefits and subjective satisfaction in using a new adhesive bone conduction hearing aid in children with congenital unilateral microtia and atresia. METHODS We evaluated the effectiveness of the hearing aid using the sound field hearing threshold, speech recognition ability under quiet and noise, and subjective questionnaires in 13 children (5-15 years old). RESULTS The mean sound field hearing threshold significantly improved with a gain of 25.4 ± 4.9 dB HL. Mean word recognition scores were ameliorated in quiet and noise by 1.9 ± 2.5% and 7.3 ± 5.3%, respectively. Speech recognition ability results in noise varied; when the speech signal and noise were presented from the front, the mean speech recognition ability improved by 2.5 ± 1.6 dB signal-to-noise ratios (SNR). When noise was presented towards the normal hearing side, speech understanding was improved by 2.9 ± 1.6 dB SNR. When the speech signal was presented from the atretic side with noise from the normal hearing side, an improvement of 5.7 ± 3.4 dB SNR (p < 0.001) was noted. However, when noise was presented towards the newly aided atretic ear, no statistical significance was found. The questionnaire results indicated that the hearing device provided benefits in speech recognition ability in different complex situations, with high satisfaction rates. CONCLUSION The adhesive bone conduction hearing aid investigated here offers a concealed and aesthetic method to improve hearing in children with congenital unilateral microtia and atresia during their early years, with high subjective satisfaction.

Abstract
Background The aim of this study was to assess the effectiveness of bone conduction hearing aids in children under 2 years old who have congenital microtia and atresia. Material/Methods This prospective study involved 42 children under 2 years old with congenital microtia and atresia who were divided into 2 groups: 21 with unilateral defect and 21 with bilateral defect. All children were provided with bone conduction hearing aids on a softband. Air and bone auditory thresholds were assessed by auditory brainstem responses (ABRs). The LittlEARS questionnaire was used to evaluate auditory development at baseline and after 6 months of hearing aids use. Behavioral observation audiometry (BOA) was used to assess auditory thresholds and compare aided and unaided hearing. Results After 6 months of hearing aid use, the total score of the LittlEARS questionnaire in children with unilateral defect was 24±5.60, while children with bilateral defect achieved a result of 26.29±6.17. Hearing thresholds in both groups with bone conduction hearing aids improved significantly and approached the normal level. Conclusions Our results confirm that bone conduction hearing aids provide an effective method of auditory rehabilitation for children with conductive and mixed hearing loss caused by microtia and atresia. Using bone conduction hearing aids in such children is crucial for proper hearing, speech, and language development.

Abstract
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.

[PMID: 33831862 DOI: 10.1159/000514087] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/29/2020] [Accepted: 12/28/2020] [Indexed: 11/19/2022] Open
Abstract
BACKGROUND The ADHEAR™ system (MED-EL, Innsbruck, Austria) is a nonsurgical bone conduction device (BCD) to treat conductive hearing loss (CHL) and single-sided deafness. In contrast to the nonsurgical alternatives on headbands or spectacle frames, the audio processor of ADHEAR is placed retroauricularly on an adhesive adapter. The published evidence on the performance of this system is limited to studies with a trial period of 2-8 weeks. OBJECTIVE This study assesses audiological and subjective outcomes over a period of 12 months, on patients with congenital aural atresia (CAA) using the ADHEAR hearing system. METHOD Fifteen children (mean age: 9.4 ± 4 years; range: 5-16 years) diagnosed with CAA (7 uni/8 bilateral) were included in this prospective, observational, repeated-measures study. Each subject used ADHEAR for 1 year, and the performance was evaluated after 1, 6, and 12 months. Free-field audiometry and speech discrimination tests were performed, and hearing-, general health- and device-specific questionnaires were used. RESULTS The unaided sound field threshold improved from an average PTA4 of 63.6 ± 3.4 dB HL to an aided average PTA4 of 29.3 ± 3.0 dB HL after 1 month of device use. The word recognition score (WRS) improved from an average of 27.9 ± 15.9% unaided to an aided average WRS of 91.3 ± 4.4% (p = 0.0003) after 1 month, 92.0 ± 4.1% (p = 0.0002) after 6 months, and 92.7 ± 5.3% (p < 0.0001) after 12 months using the ADHEAR system compared to the unaided condition for all 3 time points. The improvements in the speech in noise at 1, 6, and 12 months were as well consistent over time. The average improvement at the signal to noise ratio (SNR) of +5 dB was 58% and 53% at the SNR of +0 dB. No complications were reported, and all patients continued to use the ADHEAR after the study end. The questionnaire results revealed high user satisfaction and an average wearing time of 12 h per day. CONCLUSION This 12-month trial of the nonsurgical adhesive BCD in CAA patients showed sufficient and reliable audiological and subjective outcomes, long wearing time, and high acceptance. The ADHEAR can be considered a suitable option to treat children with CAA for the given indication, without the drawbacks of nonsurgical devices that use pressure for retention of the audio processor or the costs and possible complications involved with a surgical alternative.

Abstract
OBJECTIVE Different bone conduction hearing aids (BCHA) are commercially available. They are attached to the head in different ways. The aim of this work is an experimental evaluation of the performance of a new transcutaneous (surface mounted via adhesive pad) actuator of a BCHA. MATERIAL AND METHODS Experiments were conducted on a Thiel embalmed whole head cadaver specimen. The electromagnetic actuators from a commercial BCHA (Adhear) was used to provide stepped sine stimulus in the range of 0.1-10 kHz. The BCHA was coupled to a skin surface adhesion that was placed on the mastoid. The response was monitored as motions of the ipsi- and contralateral promontory, and as motions of the ipsi-, top- and contralateral skull surface. Promontory motion was quantified via a three-dimensional laser Doppler vibrometer (3D LDV) system. Analogously, surface motion was registered by sequentially measuring ~200 points on the skull surface (~ 15-20 mm pitch) via 3D LDV. The data were compared to corresponding measurements obtained with a Baha Power that was coupled to skin on the Mastoid via a 5 Newton steelband. RESULTS Ipsilateral and contralateral promontory vibration for stimulation with the Adhear are comparable to stimulation with the Baha Power on the 5 Newton steelband with regard to frequency dependent amplitude and phase, as well as the contribution of the motion components. The surface motion of the skull experiences a similar complex motion for both stimulation modes. CONCLUSIONS Although the Adhear is coupled without any pressure to the skin over the mastoid whereas the Baha power is attached with a 5 Newton steelband, the vibration parameters investigated are comparable.

Longitudinal study of use of the pressure free, adhesive bone conducting hearing system in children at a tertiary centre. Int J Pediatr Otorhinolaryngol 2020; 138:110307. [PMID: 32810685 DOI: 10.1016/j.ijporl.2020.110307] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/02/2020] [Revised: 07/13/2020] [Accepted: 08/05/2020] [Indexed: 11/23/2022]
Abstract
OBJECTIVES To assess the long-term compliance and usability of the non-implantable, adhesive bone conduction hearing aid system in children. Review of patient demographics, compliance and continued use. Identification of factors that impact on future patient selection. METHODS Retrospective case series review of all children aged 5 and above fitted with the adhesive bone conduction hearing aid at a paediatric tertiary centre in the UK between 2015 and 2019. Data collected from medical and audiological records. Patient demographics, skin complications, patient feedback and changes in hearing aid provision were recorded. RESULTS 82 children (40 female, 42 male) were provided with 89 adhesive hearing devices. To date 72 (87.8%) of the fitted patients, continue to use the device daily with minimal reported skin complications. Of the 10 patients that no longer use the adhesive aid, 5 no longer use any hearing device at all and the remaining 5 patients use an alternative hearing system. These include spectacle aids (n = 2) and bone anchored hearing implant (n = 3). CONCLUSION Adhesive aid products are reported to provide comparable audiological results to the commercial softband hearing aids. They provide an excellent alternative in the treatment of conductive hearing loss without the costs and possible complications of a surgical intervention. A compliance rate of 87.8% of all patients fitted with the adhesive system demonstrates a high level of patient satisfaction. The device may also provide an appropriate stepping stone to implanted device once a child reaches the age in which an autonomous decision can be made. Limitations of the device have been the variability in the longevity of the adhesive adaptor and interference with headscarves, hats and glasses with a low frequency of transient minor skin reactions reported.

The Use of a Novel, Nonsurgical Bone Conduction Hearing Aid System for the Treatment of Conductive Hearing Loss. Otol Neurotol 2020; 41:948-955.

Abstract
OBJECTIVE Conventional bone conduction hearing aid solutions often require a cumbersome retention system such as a headband or cap. This study aims to determine if a novel, nonsurgical bone conduction aid utilizing an adhesive attachment over the mastoid is equivalent to the conventional bone conduction hearing aid (BCHA) for the management of conductive hearing loss. STUDY DESIGN Prospective, single-subject randomized, crossover trial. SETTING Tertiary referral center. PATIENTS Eleven adults and 1 child between 11 and 70 years of age with unilateral conductive hearing loss were enrolled. INTERVENTION Patients had their baseline hearing assessed and were randomized to receive either the novel device or BCHA headband system. Hearing loss etiologies were varied and included cholesteatoma, otosclerosis, chronic otitis media, and previous head and neck surgery. Patients had their baseline hearing assessed and trialled both the novel device or the BCHA headband system. Patients were randomly assigned one device which was worn for 2 weeks followed by a 2-week trial with the alternate device. MAIN OUTCOME MEASURE Pure-tone thresholds and speech discrimination in quiet and noise were tested and patients also completed the short form of the Speech Spatial and Quality of Hearing (SSQ) questionnaire. RESULTS The mean unaided 4 frequency pure-tone average (PTA) air conduction threshold was 53.9 dB, bone conduction was 11.9 dB, and the mean air bone gap was 42 dB in the target ear. One patient with an adhesive skin reaction could not complete the protocol. Aided PTA and threshold testing between 250 Hz to 8000 Hz showed statistically equivalent results between both devices. The aided CNC word score, signal-to-noise ratio, and SSQ scores were also equivalent between both devices. CONCLUSION The novel bone conduction aid demonstrates equivalent performance to the conventional BCHA headband solution. The novel device should be considered an alternative option where the cosmetic and comfort issues of a headband worn device are a concern.
