“…Comparison to other treatment options was performed for SSD patients and contralateral routing of signals devices with a within‐subject design 22 . A single study reported the difference between patients with softband and a subset of patients with implanted devices 23 . Studies with only softband results were excluded.…”

“…The table presents the average data reported per study. The average aided thresholds reported per study varied between 16 and 45 dB in hearing level (HL) (4‐pure tone average [PTA4], an average of 0.5, 1, 2 and 4 kHz in all studies except one 23 where the PTA was calculated across all measured frequencies). The average aided threshold was 33.1 dB HL.…”

Background Bone‐anchored hearing systems (BAHSs) are widely used for hearing rehabilitation and are indicated in cases of conductive and mixed hearing loss and in single‐sided deafness. The Ponto system, that is one available option, has been on the market since 2009. Objective of review The aim of this study is to systematically review the literature reporting on the Ponto system, with regard to audiological and surgical outcomes and patient's quality‐of‐life scores. Type of review A systematic literature search was performed in the PubMed database 2009‐July 2019. Search strategy Search term: ((osseointegrated hearing aid) OR (bone conduction implant) OR (bone anchored hearing) OR BAHA OR BAHS OR BAHI). Pre‐defined inclusion and exclusion criteria were applied. Evaluation method English‐language articles reporting original clinical data (audiological, surgical or quality‐of‐life outcomes) on the Ponto system were included. Articles reporting on Ponto and another BAHS system where the results on Ponto constituted less than 50% of the patient population or including only results on testband or softband devices were excluded. Results Audiological outcomes were discussed in 20 publications. Improvement against the unaided thresholds was demonstrated. The functional improvement was on average 33.9 dB. The effective gain or remaining air‐bone gap was on average 6.7 dB. All evaluated data showed aided speech reception thresholds significantly below normal speech level. Twenty‐seven publications reported surgical and follow‐up data for the Ponto system. Implant survival was 97.7%, adverse skin reactions (Holgers ≥ 2) were 5% across visits and 15% across patients. No complications were life‐threatening, causing permanent disability/damage or requiring a hospitalisation. Five studies reported quality of life using the Glasgow benefit inventory, 98% reported an improvement when analysing the score on an individual level. Conclusions The outcomes of this systematic review confirm that percutaneous systems provide consistent audiological benefits and improved quality of life for patients. Further, the review demonstrates that the percutaneous systems are safe, with relatively low complication rates. Skin‐related complications are the most common complication type and are experienced by approximately one patient out of seven, or in less than one of 20 follow‐up visits.

“…BCHIs have been used to treat patients with bilateral conductive hearing loss, with patients wearing these devices experiencing good performance and high satisfaction. Few of these previous studies, however, have evaluated long-term outcomes in patients with bilateral microtia-atresia (7,20). After 2 years of follow-up, the complication rates were similar to those reported previously for these devices (21,22).…”

“…Patients were graded by the Jahrsdoerfer grading scale (17). BAHA and Ponto are similar percutaneous implants with a 3/4-mm long titanium screw inserted into the mastoid (20,24). The Bonebridge implant is an active transcutaneous bone conduction implant, with a magnetic implant fully inserted into the mastoid under intact skin.…”

“…Unlike children, these young adults can easily perform all the rather taxing and time consuming tests required for this study. We expect children and adolescents with a purely conductive hearing loss to become one of the important group of potential users of the SoundArc, as this is an important group for BAHS already today at our centre and at other centres worldwide [ 27 , 28 ]. Furthermore, the use of normal hearing adults allows us to study a relatively large but homogeneous group of subjects.…”

Objective To measure the audiological benefit of the Baha SoundArc, a recently introduced nonimplantable wearing option for bone conduction sound processor, and to compare it with the known softband wearing option in subjects with normal cochlear function and a purely conductive bilateral hearing loss. Methods Both ears of 15 normal hearing subjects were occluded for the time of the measurement, yielding an average unaided threshold of 49 dB HL (0.5 – 4 kHz). Soundfield thresholds, speech understanding in quiet and in noise, and sound localization were measured in unaided conditions and with 1 or 2 Baha 5 sound processors mounted on either a softband or a SoundArc device. Results Soundfield thresholds and speech reception thresholds were improved by 19.5 to 24.8 dB (p<.001), when compared to the unaided condition. Speech reception thresholds in noise were improved by 3.7 to 4.7 dB (p<.001). Using 2 sound processors rather than one improved speech understanding in noise for speech from the direction of the 2nd device and sound localization error by 23° to 28°. No statistically significant difference was found between the SoundArc and the softband wearing options in any of the tests. Conclusions Bone conduction sound processor mounted on a SoundArc or on a softband resulted in considerable improvements in hearing and speech understanding in subjects with a simulated, purely conductive, and bilateral hearing loss. No significant difference between the 2 wearing options was found. Using 2 sound processors improves sound localization and speech understanding in noise in certain spatial settings.
