Is BONEBRIDGE a Good Hearing Solution for Children?
Successfully implanted thousands of times for more than a decade and backed by extensive scientific data, BONEBRIDGE has long been established as the world’s most advanced active bone conduction (BC) implant system. No other active BC implant can match BONEBRIDGE in terms of market experience and reliability data. While there are absolutely no doubts about the general performance and safety of this implant, a very specific patient group has recently become the focus of clinical and scientific attention: Children. This has to do with the fact that, although BONEBRIDGE’s official CE approval is for ages five and over, very young children are increasingly receiving BONEBRIDGE implants. The studies concerned show excellent results in children under five years of age. And in some studies it has even been suggested that the official age limit for BONEBRIDGE should be reconsidered since BB can also be successfully implanted in children under 5 years.1,2,3 This leads us to the central question we would like to explore in this article: What makes BONEBRIDGE a suitable hearing solution for children?
In general, the advantages BONEBRIDGE offers adult users also apply to very young users and sometimes even more so, especially since the BCI 602 implant meets the special requirements of pediatric implantation (smaller, thinner bones, rapid bone growth, etc.). In addition, the external part of the BONEBRIDGE system, the SAMBA 2 audio processor, has very special features for children, which we will also address in this article.
Superior Hearing Performance
As with other hearing implants, early BONEBRIDGE implantation generally supports achieving the best possible hearing results since this is during the brain’s developmental stage. BONEBRIDGE serves as a solution for children with conductive hearing loss, single-sided deafness, or mixed hearing loss. It immediately provides a natural sense of sound the instant it is activated. From the moment of BONEBRIDGE activation, children experience a significant, as well as long-term and stable, increase in hearing performance and speech comprehension.4 Several studies demonstrate the effectiveness and significant audiological benefits of BONEBRIDGE in children.1,5,6,7,8,9

Long-Term Reliability With the Lowest Complication Rate
BONEBRIDGE’s long-term reliability figures are impressive. Knowing that you have chosen an exceptionally stable implant that will function perfectly in the long term is an important factor, especially in the case of patients in their childhood. After all, we want to avoid complications and possibly lengthy follow-up treatments and follow-up therapies, especially in the youngest patients.
All technical failures are included, including failures that can be traced back to external forces.
The complication and reliability rates are significantly better with BONEBRIDGE than with bone conduction implant systems from other manufacturers.14This is not due to luck or chance, but to a number of unique safety features brought about by BONEBRIDGE’s innovative design.
The most obvious factor contributing to BONEBRIDGE’s low complication rate is its active, transcutaneous technology. The implant is placed fully under intact, healthy skin. Compared with percutaneous BC systems, which are associated with a higher risk of complications,11,12 BONEBRIDGE has the advantage that it does not cause a permanent wound, thus making daily wound care obsolete. Especially in children, caring for such wounds to avoid painful infections involves considerable effort, demanding continuous attention and care. And when compared to transcutaneous passive BC systems, BONEBRIDGE sets itself apart with its pressure-free signal transmission that also contributes to healthy skin and all-day wearing comfort.
Flat, Embedded Transducer and Stable Two-Point Fixation
Another feature that plays into the favor of treating children with BONEBRIDGE is the low height of the ergonomically shaped transducer and its placement in the bony bed. Both address the specific anatomical challenges of pediatric patients, such as cranial curvature, bone growth, and thin skin. Virtual data collected via CT images showed that the BCI 602 could be fully embedded in the mastoid in 100% of the children over 12 years included and in 75% of children between 3 and 5 years (with 80% using the 1-mm BCI 602 lifts).3
The low-profile transducer, in combination with the exceptionally bendable transition of the BONEBRIDGE implant (which can bend up to 90 degrees in either lateral direction and medially up to 30 degrees to accommodate the curvature of the skull), facilitates surgical planning in children by providing the greatest possible flexibility in positioning of both the transducer and the coil section. Drilling of the bone bed in which the transducer is placed is performed with optimal visibility. The operation is quick to perform, standardized, and safe.1,2,6,13
The flexibility of the implant facilitates surgical placement.
Once the implant is securely embedded under the skin , it has a much smaller implant footprint than comparable systems. The only active and transcutaneous BC competitor on the market protrudes at least 4.9 mm, resulting in a bulge in the skin that is clearly visible from the outside. This is not the case with BONEBRIDGE.
Apart from cosmetic and skin-related aspects, the partial recession of the implant in the bone provides high stability and resistance, which is particularly important in children who tend to move around a lot and can be quite lively as they explore their surroundings.
Implant fixation is both simple and secure thanks to the two self-drilling screws that are supplied with the implant.

Compatible With Other Kinds of Therapy and Technology
When choosing a hearing implant system for children, it is important to keep in mind that the implant should not stand in the way of future treatments, but should allow them to take place without any restrictions. Depending on the patient’s history, the cause of the hearing loss, and any associated deformities or diseases, a variety of additional tests and procedures may be required after implantation. And even in an ideal case with the absence of further circumstances requiring medical treatment, an accident, for example, can lead to an unexpected MRI examination. This raises the importance of access to MRI scans with the chosen hearing implant.
BONEBRIDGE allows access to MRIs at any time.15 The implant does not need to be removed for the MRI scan16, saving children from additional surgeries on the one hand and troublesome hearing interruptions on the other.
In addition, BONEBRIDGE leaves the children’s ear canal completely untouched and, depending on the position of the incision, with many options for cosmetic procedures, such as reconstruction of the pinna in the case of external ear atresia.13
Once BONEBRIDGE has been implanted, this certainly does not mean that the end of the technological road has been reached for these children. The implant is designed to be compatible with future audio processor technologies including those not yet in development. Children with the same implant will, therefore, continue to benefit from the latest BONEBRIDGE processors on the market for many years to come in the future.
SAMBA 2: Child-Friendly Design
The compact, slim design and low weight (9.3 g including magnet and battery) make the BONEBRIDGE system’s SAMBA 2 audio processor the ideal choice for children. It can be worn very discreetly, but can also be creatively decorated with one of countless Design Covers if desired. All in all, the Design Covers, which can be changed in just a few simple steps, are available in 8 subtle basic colors and 15 artistic designs.
From monsters to pirates, there are Design Covers for both the young, and the young at heart.
Long Wearing Time & Battery Life
The audio processor is held securely on the head by magnetic attraction. It sits securely in place without exerting uncomfortable pressure on the skin. SAMBA 2 is comfortable to wear, and this is reflected in its long wearing time.1
This long wearing time is supported by its exceptionally efficient power consumption. The SAMBA 2 lasts up to 10 days on a single battery, which is significantly longer than comparable BC processors from its competitors.
Effortless Handling & Practical App for Parents
With its intuitive and simple handling, SAMBA 2 is ideal for children. No need to manually change programs: The SAMBA 2 automatically detects the environment and quickly and seamlessly adapts to the most suitable program. At the same time, parents and other caregivers can conveniently access settings and processor information, such as battery level, via a smartphone app.
Features for Children: From School to the Swimming Pool
The universal assistive listening device SAMBA 2 GO ensures optimal sound and voice quality even over longer distances and in noisy environments. It can be connected to smartphones and tablets, for example, and also to FM systems in the classroom.
When frolicking, playing, and splashing around, practical accessories such as the various attachment clips and WaterWear protective coversprovide complete water protection. This means there are no limits to fun and no need to sacrifice safety or hearing quality.
Committed to Future Innovation
The BONEBRIDGE implant will also be compatible with all future BONEBRIDGE audio processors . This makes it possible for children to keep the implant and still benefit from the latest processor technology.

Bottom Line: The Ideal Hearing Solution for Children
The BONEBRIDGE can provide an ideal solution for children with conductive hearing loss, single-sided deafness, or mixed hearing loss. Not only is it the most advanced active transcutaneous bone conduction implant but it’s also been on the market the longest. BONEBRIDGE’s thousands of implantations and impressive long-term reliability figures speak for themselves. The flat transducer is securely embedded in the bone with two self-drilling screws for easier implant fixation. The active technology provides excellent hearing outcomes across a wide range of candidacies, the placement of the implant under the skin minimizes the risk of complications, and transcutaneous, pressure-free signal transmission delivers maximum wearing comfort. Last but not least, BONEBRIDGE enables easy access to MRI examinations and has an extremely child-friendly audio processor, SAMBA 2.
