“…The incidence of post-operative pain also has been reported as relatively low for the BCI601 [32], such complaints were not reported in our cohort, neither for the BCI601 nor for the BCI602. Among our patients, high satisfaction with the audiological benefit is communicated; comfort-and improved aesthetics of the Bonebridge with its low profile, especially in comparison to the pre-OP trial-devices, is reported, which is in coherent with the literature [33][34][35][36][37][38][39][40].…”

Purpose The study aimed to evaluate audiological benefits, quality of hearing and safety of two Bonebridge generation: BCI601 and BCI602 (MED-EL, Innsbruck, Austria) in children. Methods Twelve children were implanted: five BCI601 and seven BCI602 comprising of ten conductive hearing loss, and two single sided deaf SSD subjects. Audiological outcomes tested were sound field audiometry, functional gain, speech recognition threshold (SRT50), speech recognition in noise (SPRINT) and localisation abilities. Subjective measures were Speech, Spatial and Qualities of Hearing Scale (SSQ12). Results The mean FG with the BCI601 was 25.0 dB and with the BCI602 28.0 dB. The benefit in SRT50 was 23.2 dB and 33.8 dB, respectively. The mean benefit in SPRINT was 15% and 6.7% and the localisation ability improved from 33.3° to 16° and from 26.2° to 17.6°, respectively. The two SSD subjects reported a FG of 17 dB, a benefit in SRT50 of 22.5 and a benefit in SPRINT of 20%. Subjective outcomes improved significantly and even exceeded the values of their age-and sex matched normal hearing peers. One revision was reported: a retroauricular emphysema above the implant occurred 12 months post-OP, it was resolved operatively with the implant still being functional. Conclusion The pediatric cohort reports significant audiological benefit, even exceeding that of the age- and sex matched control. The combination of the high safety and audiological benefit makes the Bonebridge a comfortable and effective option in hearing rehabilitation in children.

“…11 Among our patients, satisfaction with the audiological benefit, comfort, and aesthetics of the BB is high and that corresponds with what is seen in the literature. [3][4][5][6][7] The system also is well regarded for its low profile and aesthetic appearance of the processor, which is greatly appreciated especially by child patients. Most children also report very good results in communication and using the audio processor on a day-to-day basis, while parents especially appreciate the improvement in their children's social interactions and speech development.…”

“…Most children also report very good results in communication and using the audio processor on a day-to-day basis, while parents especially appreciate the improvement in their children's social interactions and speech development. 3,6,9 Despite the high levels of satisfaction among BB users, certain complications can occur. A study conducted at the ORL clinic in Vienna during 2012 to 2018 examined 64 patients and found that 6 (9.4%) had postoperative complications requiring examination.…”

Retroauricular Emphysema as a Late Complication After Bonebridge Implantation: Case Report

et al. 2021

View full text Add to dashboard Cite

Bonebridge (BB) is the first active implantation system for bone conduction that is placed fully under the skin. Experience suggests that BB is characterized by low incidence of postoperative complications. This case report presents a rare case of a 16-year-old girl with incidence of emphysema occurring over the implant 1 year after operation. We performed a computed tomography scan that showed pockets of gas above the floating mass transducer so we provided the revision surgery and sealed the artificial opening with fat from the earlobe and fibrin glue. Since that time, no air has collected in the retroauricular area and the implant has been fully functional.

“…No major adverse events, defined by the need for revision surgery or explantation, occurred in our study. In the literature only ten major adverse events were described so far: one revision surgery due to headache [ 31 ], one implant removal because of local infection [ 34 ], one explantation due to device failure [ 33 ], one case of sudden loss of hearing benefit [ 31 ], two explantations due to lack of benefit, while these patients were outside of indication criteria [ 25 , 35 ] and four explantations due to wound dehiscence, mainly (3 cases) after implantation in a radical cavity [ 35 ]. According to other studies [ 12 , 23 , 26 , 32 ], our experience has also shown that neither the RS-approach, which is the prefered device localization in patients with radical cavities, nor the sinus and/or dura exposition and compression, or the usage of BCI lifts had any negative influence on patients outcome.…”

Purpose To evaluate the long-term benefits in hearing-related quality of life, patient satisfaction and wearing time of patients rehabilitated with an active transcutaneous bone-conduction device. Adverse events and audiological outcomes are reported as secondary outcomes. Methods This retrospective, mono-centric cohort analysis involves 16 adults with conductive or mixed hearing loss with a mean device experience of 51.25 months. Patient-reported outcome measures were assessed using the short version of the Speech, Spatial and Qualities of Hearing Scale (SSQ12-B) and the German version of the Audio Processor Satisfaction Questionnaire (APSQ). Audiological outcomes as well as incidence of adverse events were obtained from patients´ charts. Results The hearing-related quality of life improved significantly within all subscales of the SSQ12-B scoring a mean overall of 2.95 points. Patient satisfaction measured with the APSQ scored 8.8 points on average. Wearing times differed considerably and patients with lower levels of education seemed to use their device longer compared to patients with academic education. Eight minor adverse events were documented, all of which resolved during follow-up. The mean gain in word recognition score at the last follow-up measured at 65 dB was 75.9%, while speech reception threshold was lowered by 35.1 dB. Conclusion Even after several years, patients report significant benefits in hearing-related quality of life and device satisfaction. In combination with a low rate of minor adverse events and significantly improved audiological outcomes, the device is considered as a comfortable and effective option in hearing rehabilitation.
