Bone-conduction implants are a standard therapeutic option for patients with conductive, unilateral, or mixed hearing loss who either do not tolerate conventional hearing aids or can benefit from surgery. The aim of this study was to evaluate long-term medical and technical outcomes, and audiological results with the Bonebridge transcutaneous bone-conduction implant. This retrospective study included all patients implanted with a bone-conduction hearing implant at a tertiary medical referral center between March 2012 and October 2018. Medical and technical outcomes included the mean length of implant usage, medical and technical complications (skin and wound infection, lack of benefit, technical failure), explantations and revisions, coupling approaches, implant failure rate, implant survival and the implant loss for added follow-up years. Auditory results were measured by functional hearing gain and the Freiburger monosyllabic test at 65 dB sound pressure level. Sixty-four patients were included in the study; five of these were implanted bilaterally (69 devices). Five unilaterally implanted patients were lost to follow-up. The mean follow-up was 27.1 months (range: 0.2 months–6.3 years). The mean implant usage was 25.9 months (range: 0.2 months–6.3 years). Fifty-seven implants (89.1%) were in use at the end of the follow-up period. Complications occurred in six ears (9.4%). Five implants (7.8%) were explanted without reimplantation. Device failure occurred in one implant (1.6%), which was possibly caused by recurrent head trauma. The rate of implant loss due to technical device failure (damage to device) was 1 per 72 follow-up years. The mean improvement on the Freiburger monosyllabic test (52.1%, p = 0.0001), and in functional hearing gain across frequencies (26.5 dB, p = 0.0001) was significant. This single-center follow-up reveals the medical and technical reliability of a transcutaneous bone-conduction implant for hearing rehabilitation because complication and revision rates were low. The majority of patients still used the device at the end of the observation period. Implantation resulted in favorable hearing outcomes in comparison to that of unaided conditions. Cautious patient selection mainly regarding co-morbidities, the history of chronic otologic diseases and proper surgical technique seems to be crucial in reducing complications.

“…Compared to other studies, our data revealed a slightly favorable mean FG (28 dB vs. 19.2 [21], 25.2 dB [22]) in patients with atresia. The mixed-hearing loss group in our study had a mean FG of 24.1 dB, compared to two authors reporting on slightly higher FG values of 28 dB [23] and 33.5 dB [9].…”

Background Implant lifts were recently introduced to facilitate implantation of the Bonebridge and to reduce the risk of uncovering the sigmoid sinus and/or dura. Purpose The current study analyzed medical, technical, and audiological outcomes of implantation with the Bonebridge implant using lifts. Research Design This was a retrospective study on all consecutive patients implanted with a bone-conduction hearing implant at a tertiary medical referral center between March 2012 and October 2018. Outcome measures were complications, explantations, and revisions and the mean time of implant use. Audiological results were assessed as well. Outcomes were evaluated for devices implanted with BCI Lifts and compared with those implanted without lifts. Results In the study period, 13 out of a total of 54 implantations were conducted using one or two 1- to 4-mm BCI Lifts. During the follow-up period, two complications occurred and both in patients implanted without lifts (2/41; 4.9%). All patients in the lifts group were using the implant at the end of observation period. No statistically significant difference was observed in functional hearing gain or word-recognition improvement at 65 dB between two groups. Conclusions The use of BCI Lifts in Bonebridge implantations was not associated with adverse events during the observation period. The clinical follow-up revealed no complications in implantations requiring lifts. Furthermore, the functional hearing gain and the word-recognition improvement did not differ from those of devices implanted without lifts. Data indicate safety and efficacy for Bonebridge implantations using lifts.

Introduction The transmastoid approach is the most recommended technique to Bonebridge surgery, while in patients with bad anatomy or in the canal wall down technique, retrosigmoid or Middle Fossa Approaches are the alternative surgical options. Objective To describe a novel alternative approach called inverted middle fossa approach (IMFA) and its technique and audiological outcomes. Methods Seven patients submitted to the IMFA were included. All patients presented conductive and mixed hearing loss with bone thresholds of the audiogram > 40 dB. The audiological test was conducted pre- and postoperatively. Results A total of 5 males and 2 females, aged 13,8 years old (range 6–25 years old) were studied. The average follow-up was of 20 months (12 to 32 months). All patients presented aural atresia, except one with severe osseous-fibrous dysplasia of the temporal bone. Two patients showed bilateral compromise, three patients had associated Goldenhar and Treacher Collins syndrome. On the preoperative audiograms, air conduction (AC) thresholds showed a PTA4 (0.5, 1, 2 and 4 kHz) of 66.7 dB (standard deviation [SD] = ± 7.8), while the bone conduction thresholds reached an average of 11.2 dB (SD = ± 6.9). The postoperative thresholds did not change, and additional sensorineural damage was not observed before activation. Four weeks after surgery, all the patients were fitted with the external processor. The postoperative audiological aided exam showed AC PTA 4 thresholds of 18.9 dB (SD = ± 5.9). Conclusion The IMFA allows the nearest position of the microphone to the external auditory canal. The technique is a suitable option to the 3 classical approaches with similar rate of audiological results. More investigation is needed to determine the benefit of the novel approach compared with the others.
