“…All patients in this study showed improvement in hearing after the surgery, and the average PTA and SDS were statistically significantly improved after the implantation. As suggested by Lee, et al, 8) the amplification of the external sound input after the Bonebridge implantation could suppress tinnitus by masking effect.…”

“…The results from our study support their findings; SSD patients and AHL patients both showed improvement in tinnitus after Bonebridge implantation. Tinnitus questionnaires conducted by Lee, et al 8) included THI score, awareness of tinnitus and VAS score for loudness and annoyance; of these questionnaires, THI score, awareness of tinnitus and VAS score for annoyance showed a statistically significant decrease after surgery. In our study, we additionally conducted VAS score for effect on life.…”

“…12) To the best of our knowledge, only one other study has reported the effect of the Bonebridge in tinnitus to date. Lee, et al 8) reported in 2020 that the Bonebridge implantation can reduce tinnitus in patients with SNHL. They suggested that masking effect and bidirectionality of the central auditory pathway could explain tinnitus suppression in the Bonebridge recipients.…”

“…In addition to the masking effect and bidirectionality of the central auditory pathway that Lee, et al 8) suggested as possible mechanisms for tinnitus suppression in the Bonebridge, alleviation of emotional distress after the Bonebridge implantation could be another possible mechanism of tinnitus suppression. Patients with hearing loss experience emotional distress due to social isolation, which could lead to depression.…”

“…3) In addition, the bone conduction floating mass transducer (BC-FMT) of the Bonebridge is placed in a subperiosteal plane, thus reducing the rate of post-operative complications such as skin regrowth and infection. 4) Although many studies have reported the beneficial effect of the Bonebridge on hearing, [3][4][5][6][7] to the best of our knowledge, there has been only one other study by Lee, et al 8) regarding the effect of the Bonebridge on tinnitus. Thus, in this study, we investigated the effect of the Bonebridge on tinnitus as a sound therapeutic modality of tinnitus in patients with AHL or SSD.…”

Background and ObjectivesThe objective of this study was to investigate the effect of an active transcutaneous bone conduction implant (BCI) of Bonebridge (MED-EL) on tinnitus patients with asymmetric hearing loss (AHL) or single-sided deafness (SSD). Subjects and Method Medical records and tinnitus questionnaires were reviewed retrospectively of patients with AHL or SSD, who received Bonebridge by a single surgeon at Seoul St. Mary's Hospital from 2017 to 2021. Audiologic evaluation and tinnitus questionnaires were conducted before and after surgery. Results Of the 17 patients, 8 patients had SSD and 9 patients had AHL, and 13 patients (76.47%) had tinnitus before surgery while 4 patients did not. No patient showed newly developed tinnitus after surgery. After implantation, three patients (23.08%) showed a complete resolution of tinnitus. All patients showed significant improvement in hearing level after surgery. The mean tinnitus handicap inventory (THI) score and visual analogue scale (VAS) score for effect on life showed a significant decrease after surgery, from 43.1±28.2 to 29.7±25.7 (p<0.05), and 4.7±2.9 to 3.2±3.3 (p<0.05), respectively. The mean THI scores of seven AHL patients and seven patients with tinnitus on the implanted ear were significantly decreased after implantation from 50.9±24.7 to 34.6±27.5 (p<0.05) and from 53.1±23.4 to 37.4±15.0 (p<0.05), respectively. Conclusion BCI seems to be effective in suppressing tinnitus in the patients with AHL but not with SSD. Along with directive counseling, sound therapy with Bonebridge can decrease tinnitus in some patients with AHL.

ObjectiveTo investigate the safety and efficacy of a novel active transcutaneous bone conduction implant (BCI) device for patients with single‐sided deafness (SSD).Study DesignProspective cohort study.SettingTertiary referral hospitals.MethodsThis 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.ResultsThe 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).ConclusionThe 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.

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.
