Abstract
BACKGROUND The active transcutaneous bone conduction implant (tBCI; BONEBRIDGE™ BCI 601; MED-EL, Innsbruck, Austria) is fixed to the skull with two self-tapping screws in predrilled screw channels. The aim of this prospective study was to evaluate the safety and effectiveness of fixation with self-drilling screws instead of the self-tapping screws, in order to simplify the surgical procedure. MATERIALS AND METHODS Nine patients (mean age 37 ± 16 years, range 14-57 years) were examined pre- and 12 months postoperatively for word recognition scores (WRS) at 65 dB SPL, sound-field (SF) thresholds, bone conduction thresholds (BC), health-related quality of life (Assessment of Quality of Life, AQOL-8D questionnaire), and adverse events (AE). RESULTS Due to avoidance of one surgical step, the surgical technique was simplified. Mean WRS in SF was 11.1 ± 22.2% (range 0-55%) pre- and 77.2 ± 19.9% (range 30-95%) postoperatively; mean SF threshold (pure tone audiometry, PTA4) improved from 61.2 ± 14.3 dB HL (range 37.0-75.3 dB HL) to 31.9 ± 7.2 dB HL (range 22.8-45.0 dB HL); mean BC thresholds were constant at 16.7 ± 6.8 dB HL (range 6.3-27.5 dB HL) pre- and 14.2 ± 6.2 dB HL (range 5.8-23.8 dB HL) postoperatively. AQOL-8D mean utility score increased from 0.65 ± 0.18 preoperatively to 0.82 ± 0.17 postoperatively. No device-related adverse events occurred. CONCLUSION Implant fixation by means of self-drilling screws was safe and effective in all nine patients. There was significant audiological benefit 12 months after implantation.

Abstract
OBJECTIVE Audio processors (AP) are the external components of hearing implants. User satisfaction with the performance and comfort of their AP is a critical factor in ensuring daily use, which leads to improved hearing outcomes. The aim of this study was to construct and validate an Arabic language translation of the APSQ for use among Arabic-speaking clinicians and patients. DESIGN The original APSQ was translated into the Arabic language using cross-cultural adaptation measures. The final questionnaire was administered to CI users in electronic form. STUDY SAMPLE 117 CI users (64 female) participated. A total of 179 ears were assessed. RESULTS High levels of satisfaction with audio processors were observed among CI users. Item and scale analyses indicate that this version of the APSQ measure a homogeneous and valid construct. CONCLUSION The Arabic version of the APSQ captures user satisfaction with hearing implant audio processors.

Early Results With the New Active Bone-Conduction Hearing Implant: A Systematic Review and Meta-Analysis. Otolaryngol Head Neck Surg 2024; 170:1630-1647. [PMID: 38529662 DOI: 10.1002/ohn.728] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/14/2023] [Revised: 12/12/2023] [Accepted: 02/02/2024] [Indexed: 03/27/2024]
Abstract
OBJECTIVE The bone conduction implant (BCI) 602 is a new transcutaneous BCI with smaller dimensions. However, limited patient numbers restrict the statistical power and generalizability of the current studies. The present systematic review and meta-analysis summarize early audiological and medical outcomes of adult and pediatric patients implanted with the BCI 602 due to mixed or conductive hearing loss. DATA SOURCE Following the Preferred Reporting items for Systematic Reviews and Meta-analyses guidelines, 108 studies were reviewed, and 6 (5.6%) were included in the meta-analysis. REVIEW METHOD The data on study and patient characteristics, surgical outcomes, and audiological test results were extracted from each article. Meta-analysis employed the fixed-effect and random-effects models to analyze the mean differences (MDs) between pre- and postoperative performances. RESULTS In total, 116 patients were evaluated, including 64 (55%) adult and 52 (45%) pediatric patients. No intraoperative adverse events were reported, while postoperative complications were reported in 2 (3.1%) adult and 2 (3.8%) pediatric patients. Studies consistently showed significant improvements in audiological outcomes, quality of life, and sound localization in the aided condition. In the meta-analysis, we observed a significant difference in the unaided compared to the aided condition in sound field thresholds (n = 112; MD, -27.05 dB; P < 0.01), signal-to-noise ratio (n = 96; MD, -6.35 dB; P < 0.01), and word recognition scores (n = 96; MD, 68.89%; P < 0.01). CONCLUSION The implantation of the BCI 602 was associated with minimal surgical complications and excellent audiological outcomes for both the pediatric and the adult cohort. Therefore, our analysis indicates a high level of safety and reliability. Further research should focus on direct comparisons with other BCIs and long-term functional outcomes.

Abstract
Introduction Atresia of the external auditory canal affects 1 in every 10 thousand to 20 thousand live births, with a much higher prevalence in Latin America, at 5 to 21 out of every 10 thousand newborns. The treatment involves esthetic and functional aspects. Regarding the functional treatment, there are surgical and nonsurgical alternatives like spectacle frames and rigid and softband systems. Active transcutaneous bone conduction implants (BCIs) achieve good sound transmission and directly stimulate the bone. Objective To assess the audiological performance and subjective satisfaction of children implanted with an active transcutaneous BCI for more than one year and to compare the outcomes with a nonsurgical adhesive bone conduction device (aBCD) in the same users. Methods The present is a prospective, multicentric study. The audiological performance was evaluated at 1, 6, and 12 months postactivation, and after a 1-month trial with the nonsurgical device. Results Ten patients completed all tests. The 4-frequency pure-tone average (4PTA) in the unaided condition was of 65 dB HL, which improved significantly to 20 dB HL after using the BCI for 12 months. The speech recognition in quiet in the unaided condition was of 33% on average, which improved significantly, to 99% with the BCI, and to 91% with the aBCD. Conclusion The aBCD demonstrated sufficient hearing improvement and subjective satisfaction; thus, it is a good solution for hearing rehabilitation if surgery is not desired or not possible. If surgery is an option, the BCI is the superior device in terms of hearing outcomes, particularly background noise and subjective satisfaction.

Role of early hearing aid experience in speech recognition in patients with bilateral congenital microtia following Bonebridge implantation: a retrospective cohort study. Eur Arch Otorhinolaryngol 2024; 281:1205-1214. [PMID: 37792216 DOI: 10.1007/s00405-023-08210-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/20/2023] [Accepted: 08/21/2023] [Indexed: 10/05/2023]
Abstract
PURPOSE To identify audiological and demographic variables that predict speech recognition abilities in patients with bilateral microtia who underwent Bonebridge (BB) implantation. METHODS Fifty patients with bilateral microtia and bilateral conductive hearing loss (CHL) who underwent BB implantation were included. Demographic data, preoperative hearing aid use experience, and audiological outcomes (including pure-tone hearing threshold, sound field hearing threshold [SFHT], and speech recognition ability) for each participant were obtained. The Chinese-Mandarin Speech Test Materials were used to test speech recognition ability. The word recognition score (WRS) of disyllabic words at 65 dB SPL signals was measured before and after BB implantation in quiet and noisy conditions. RESULTS The mean preoperative WRS under quiet and noisy conditions was 10.44 ± 12.73% and 5.90 ± 8.76%, which was significantly improved to 86.38 ± 9.03% and 80.70 ± 11.34%, respectively, following BB fitting. Multiple linear regression analysis revealed that lower preoperative SFHT suggested higher preoperative WRS under both quiet and noisy conditions. Higher age at implantation predicted higher preoperative WRS under quiet conditions. Furthermore, patients with more preoperative hearing aid experience and lower postoperative SFHT were more likely to have higher postoperative WRS under both quiet and noisy testing conditions. CONCLUSIONS This study represents the first attempt to identify predictors of preoperative and postoperative speech recognition abilities in patients with bilateral microtia with BB implantation. These findings emphasize that early hearing intervention before implantation surgery, combined with appropriate postoperative fitting, contributes to optimal benefits in terms of postoperative speech recognition ability.

Abstract
OBJECTIVE To compare quality of life (QOL) outcomes of percutaneous and transcutaneous bone conduction devices (pBCD and tBCD, respectively). DATABASES REVIEWED Pubmed, Scopus, CINAHL. METHODS A systematic review was performed searching for English language articles from inception to March 15, 2023. Studies reporting QOL outcomes measured using a validated tool following implantation of either pBCDs or tBCDs were considered for inclusion. QOL outcomes included scores for Glasgow Benefit Inventory, Glasgow Children's Benefit Inventory, Abbreviated Profile of Hearing Aid Benefit, and the Speech, Spatial, and Qualities of Hearing Scale. A meta-analysis of continuous measures was performed. RESULTS A total of 52 articles with 1,469 patients were included. Six hundred eighty-nine patients were implanted with pBCDs, and the remaining 780 were implanted with tBCDs. Average Glasgow Benefit Inventory scores for the tBCD group (33.0, 95% confidence interval [22.7-43.3]) were significantly higher than the pBCD group (30.9 [25.2-36.6]) (Δ2.1 [1.4-2.8], p < 0.0001). Mean Glasgow Children's Benefit Inventory scores (Δ3.9 [2.0-5.8], p = 0.0001) and mean gain in Abbreviated Profile of Hearing Aid Benefit scores (Δ5.6 [4.8-6.4], p < 0.0001) were significantly higher among patients implanted with tBCDs than those implanted with pBCDs. Patients implanted with tBCDs also had significantly higher gains on the Speech (Δ1.1 [0.9-1.3], p < 0.0001), Spatial (Δ0.8 [0.7-0.9], p < 0.0001), and Qualities of Hearing (Δ1.2 [1.1-1.3], p < 0.0001) portions of the Speech, Spatial, and Qualities of Hearing Scale than those implanted with pBCDs. CONCLUSIONS Patients implanted with transcutaneous devices had better QOL outcomes than those implanted with percutaneous devices.

Abstract
OBJECTIVE To investigate the safety and efficacy of a novel active transcutaneous bone conduction implant (BCI) device for patients with single-sided deafness (SSD). STUDY DESIGN Prospective cohort study. SETTING Tertiary referral hospitals. METHODS This prospective multicenter study was conducted at 15 institutions nationwide. Thirty adult (aged ≥19 years) SSD patients were recruited. They underwent implantation of an active transcutaneous BCI device (Bonebridge BCI602). Objective outcomes included aided pure-tone thresholds, aided speech discrimination scores (SDSs), and the Hearing in Noise Test (HINT) and sound localization test results. The Bern Benefit in Single-Sided Deafness (BBSS) questionnaire, the Abbreviated Profile of Hearing Aid Benefit (APHAB) questionnaire, and the Tinnitus Handicap Inventory (THI) were used to measure subjective benefits. RESULTS The mean aided pure-tone threshold was 34.2 (11.3), mean (SD), dB HL at 500 to 4000 Hz. The mean total BBSS score was 27.5 (13.8). All APHAB questionnaire domain scores showed significant improvements: ease of communication, 33.6 (23.2) versus 22.6 (21.3), P = .025; reverberation, 44.8 (16.6) versus 32.8 (15.9), P = .002; background noise, 55.5 (23.6) versus 35.2 (18.1), P < .001; and aversiveness, 36.7 (22.8) versus 25.8 (21.4), P = .028. Moreover, the THI scores were significantly reduced [47.4 (30.1) versus 31.1 (27.0), P = .003]. Congenital SSD was a significant factor of subjective benefit (-11.643; 95% confidence interval: -21.946 to -1.340). CONCLUSION The BCI602 active transcutaneous BCI device can provide functional hearing gain without any adverse effects and is a feasible option for acquired SSD patients with long-term deafness.

Abstract
OBJECTIVE To evaluate the magnetic resonance (MR) image artifact and image distortion associated with the two transcutaneous bone conduction implants currently available in the United States. STUDY DESIGN Cadaveric study. METHODS Two cadaveric head specimens (1 male, 1 female) were unilaterally implanted according to manufacturer guidelines and underwent MR imaging (General Electric and Siemens 1.5 T scanners) under the following device conditions: (1) no device, (2) Cochlear Osia with magnet and headwrap, (3) Cochlear Osia without magnet, and (4) MED-EL Bonebridge with magnet. Maximum metal mitigation techniques were employed in all conditions, and identical sequences were obtained. Blinded image scoring (diagnostic vs nondiagnostic image) was performed by experienced neuroradiologists according to anatomical subsites. RESULTS All device conditions produced artifact and image distortion. The Osia with magnet produced diagnostic T1- and T2-weighted images of the ipsilateral temporal bone, however, non-echo planar imaging diffusion-weighted imaging (DWI) was nondiagnostic. The Osia without magnet scanned on the Siemens MR imaging demonstrated the least amount of artifact and was the only condition that allowed for diagnostic imaging of the ipsilateral temporal bone on DWI. The Bonebridge produced a large area of artifact and distortion with the involvement of the ipsilateral and contralateral temporal bones. CONCLUSION In summary, of the three device conditions (Osia with magnet, Osia without magnet, and Bonebridge), Osia without magnet offered the least amount of artifact and distortion and was the only condition in which diagnostic DWI was available for the middle ear and mastoid regions on the Siemens MR imaging scanner.

Abstract
OBJECTIVE Recently, the Bonebridge 602 implant was introduced. Its smaller dimensions facilitate implantation even in surgically demanding cases. However, in extreme anatomical conditions, implant lifts are still required. We intended to report on the medical and audiological outcomes of all patients implanted with the implant with a secondary focus on the safety, efficacy, and feasibility of the use of 1-mm lifts. STUDY DESIGN Retrospective cohort study. SETTING Tertiary academic center. METHODS We retrospectively analyzed all patients implanted with the Bonebridge 602. Patient demographics and surgically-specific data were collected from the medical charts. Furthermore, audiological results were assessed. Outcomes were compared between implantations with versus without lifts. RESULTS Twenty-one devices were implanted during the study period. Satisfactory audiological results were observed, while no intra- or postoperative adverse events occurred. The majority of patients were daily users at the end of the observation period (n = 20/21, 95.2%), and one patient (n = 1/21, 4.8%) was a nonuser after 6 months of use because of subjective dissatisfaction. Due to anatomical considerations, 1-mm lifts were used in 4 implantations (19.0%). The application of lifts did not result in prolonged surgical times, complications, or shorter time of use, nor did it negatively affect audiometric results. CONCLUSION Implantations with the new and smaller Bonebridge were associated with gratifying medical and audiological outcomes. Still, in extreme anatomical conditions, 1-mm lifts are necessary. Nonetheless, surgical placement with the help of lifts seems safe, effective, and feasible, and is a viable option in cases with challenging anatomies due to previous surgeries or anomalies.

Abstract
BACKGROUND The active transcutaneous bone conduction implant (tBCI; BONEBRIDGE™ BCI 601; MED-EL, Innsbruck, Austria) is fixed to the skull with two self-tapping screws in predrilled screw channels. The aim of this prospective study was to evaluate the safety and effectiveness of fixation with self-drilling screws instead of the self-tapping screws, in order to simplify the surgical procedure. MATERIALS AND METHODS Nine patients (mean age 37 ± 16 years, range 14-57 years) were examined pre- and 12 months postoperatively for word recognition scores (WRS) at 65 dB SPL, sound-field (SF) thresholds, bone conduction thresholds (BC), health-related quality of life (Assessment of Quality of Life, AQOL-8D questionnaire), and adverse events (AE). RESULTS Due to avoidance of one surgical step, the surgical technique was simplified. Mean WRS in SF was 11.1 ± 22.2% (range 0-55%) pre- and 77.2 ± 19.9% (range 30-95%) postoperatively; mean SF threshold (pure tone audiometry, PTA4) improved from 61.2 ± 14.3 dB HL (range 37.0-75.3 dB HL) to 31.9 ± 7.2 dB HL (range 22.8-45.0 dB HL); mean BC thresholds were constant at 16.7 ± 6.8 dB HL (range 6.3-27.5 dB HL) pre- and 14.2 ± 6.2 dB HL (range 5.8-23.8 dB HL) postoperatively. AQOL-8D mean utility score increased from 0.65 ± 0.18 preoperatively to 0.82 ± 0.17 postoperatively. No device-related adverse events occurred. CONCLUSION Implant fixation by means of self-drilling screws was safe and effective in all nine patients. There was significant audiological benefit 12 months after implantation.

Abstract
PURPOSE The SAMBA 2 BB audio processor for the BONEBRIDGE bone conduction implant features a new automatic listening environment detection to focus on target speech and to reduce interfering speech and background noises. The aim of this study was to evaluate the audiological benefit of the SAMBA 2 BB (AP2) and to compare it with its predecessor SAMBA BB (AP1). METHODS Prospective within-subject comparison study. We compared the aided sound field hearing thresholds, speech understanding in quiet (Freiburg monosyllables), and speech understanding in noise (Oldenburg sentence test) with the AP1 and AP2. Each audio processor was worn for 2 weeks before assessment and seven users with single-sided sensorineural deafness (SSD) participated in the study. For speech understanding in noise, two complex noise scenarios with multiple noise sources including single talker interfering speech were used. The first scenario included speech presented from the front (S0NMIX), while in the second scenario speech was presented from the side of the implanted ear (SIPSINMIX). In addition, subjective evaluation using the SSQ12, APSQ, and the BBSS questionnaires was performed. RESULTS We found improved speech understanding in quiet with the AP2 compared to the AP1 aided condition (on average + 17%, p = 0.007). In both noise scenarios, the AP2 lead to improved speech reception thresholds by 1.2 dB (S0NMIX, p = 0.032) and 2.1 dB (SIPSINMIX, p = 0.048) compared to the AP1. The questionnaires revealed no statistically significant differences, except an improved APSQ usability score with the AP2. CONCLUSION Clinicians can expect that patients with SSD will benefit from the SAMBA 2 BB by improved speech understanding in both quiet and in complex noise scenarios, when compared to the older SAMBA BB.

Multicentric study on surgical information and early safety and performance results with the Bonebridge BCI 602: an active transcutaneous bone conduction hearing implant. Eur Arch Otorhinolaryngol 2023; 280:1565-1579.

Abstract
AIM This European multicentric study aimed to prove safety and performance of the Bonebridge BCI 602 in children and adults suffering from either conductive hearing loss (CHL), mixed hearing loss (MHL), or single-sided sensorineural deafness (SSD). METHODS 33 patients (13 adults and 10 children with either CHL or MHL and 10 patients with SSD) in three study groups were included. Patients were their own controls (single-subject repeated measures), comparing the unaided or pre-operative to the 3-month post-operative outcomes. Performance was evaluated by sound field thresholds (SF), word recognition scores (WRS) and/or speech reception thresholds in quiet (SRT) and in noise (SNR). Safety was demonstrated with a device-specific surgical questionnaire, adverse event reporting and stable pure-tone measurements. RESULTS The Bonebridge BCI 602 significantly improved SF thresholds (+ 25.5 dB CHL/MHL/SSD), speech intelligibility in WRS (+ 68.0% CHL/MHL) and SRT in quiet (- 16.5 dB C/MHL) and in noise (- 3.51 dB SNR SSD). Air conduction (AC) and bone conduction (BC) thresholds remained stable over time. All adverse events were resolved, with none unanticipated. Mean audio processor wearing times in hours [h] per day for the CHL/MHL group were ~ 13 h for adults, ~ 11 h for paediatrics and ~ 6 h for the SSD group. The average surgical length was 57 min for the CHL/MHL group and 42 min for the SSD group. The versatility of the BCI 602 (reduced drilling depth and ability to bend the transition for optimal placement) allows for treatment of normal, pre-operated and malformed anatomies. All audiological endpoints were reached. CONCLUSIONS The Bonebridge BCI 602 significantly improved hearing thresholds and speech understanding. Since implant placement follows the patient's anatomy instead of the shape of the device and the duration of surgery is shorter than with its predecessor, implantation is easier with the BCI 602. Performance and safety were proven for adults and children as well as for the CHL/MHL and SSD indications 3 months post-operatively.

Abstract
OBJECTIVE To evaluate clinical and audiometric outcomes of adult and pediatric patients implanted with a semi-implantable transcutaneous active bone-conduction implant. STUDY DESIGN Retrospective chart review. SETTING Two tertiary referral centers. PATIENTS Subjects implanted with the semi-implantable transcutaneous active bone-conduction implant called BoneBridge. INTERVENTION Implantation of the BoneBridge and audiometric evaluations. MAIN OUTCOME MEASURES Audiometric, clinical, and surgical outcomes as well as complications. RESULTS Forty-two adults and 20 children were implanted for conductive or mixed hearing loss as well as single-sided deafness. Implantation significantly improved mean air-conduction pure-tone average from 72.8 ± 22.3 to 35 ± 9 dB in adults and from 65.7 ± 24.3 to 19.6 ± 8.2 dB in children (both p < 0.001). Word recognition score improved from 63.7 ± 38.8% to 85.6 ± 10.6% in adults and 57.8 ± 38% to 89.3 ± 10.1% in children (both p < 0.05). The rate of revision surgery was 11.3%, with four patients (6.5%) undergoing removal for device-related complications, two (3.2%) for complications associated with implantation, and one (1.6%) for device failure secondary to external trauma. CONCLUSIONS In a large retrospective series consisting of both pediatric and adult patients, implantation with a transcutaneous active bone-conduction implant was found to be a reliable aural rehabilitation option for a variety of hearing loss etiologies.

Abstract
Implantable bonebridge(BB) is suitable for patients over 5 years with conductive/mixed hearing loss and unilateral deafness, and the surgical approach depends on the anatomical structure of the patient's ear. Recent studies have shown that compared with other implantable hearing devices, implantable BB have more efficient hearing gain and lower incidence of complications. However, the postoperative effect of implantable BB on unilateral deafness patients and the poor compensation of low-frequency hearing threshold need to be further studied. This article reviews the clinical research on implantable BB, so as to provide some reference for clinicians to select hearing devices for patients individually.
