Implantable bone conduction hearing systems are intended for patients with a conductive or mixed hearing loss, in whom other treatment options do not provide sufficient benefits or are contraindicated. In general, they are called BAHDs (bone-anchored hearing devices) and they transform acoustic energy into vibrations transferred by a titanium implant through cranial bones to cochlea and fluids of the inner ear. The implantable bone conduction hearing systems are classified as passive and active based on the location of the vibration unit. The review describes the basic types of passive systems, their advantages and disadvantages. Special attention is paid to the Bonebridge active bone conduction system which represents a state-of-the-art, efficient and patient-friendly treatment method that removes the disadvantages of passive implantable systems.

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.

BACKGROUND/AIM: Hearing impairment affects a small but significant percentage of newborns (0.1-0.4%). Newborn hearing screening (NHS) is recommended for early detection and treatment. The implementation of NHS can vary among countries. In this study, we present the methodology, organization, and technical requirements of NHS. This study analyzed results from a tertiary hospital, identified issues, and proposed solutions. PATIENTS AND METHODS: In the studied region, there are five maternity hospitals and a perinatal intensive care center and in 2020, there were 5,864 live births. Screening is performed at three levels. The first screening is conducted on the 2nd-3rd day of a newborn's life in a maternity hospital, the first rescreening on the 3rd-6th week at a relevant ENT department, and the second rescreening on the 3rd-6th month of life at the regional screening center where the central database is also held. RESULTS: In the studied region, 5,793 out of 5,864 (98.79%) newborns received NHS in 2020. Of these, 120 (2.07%) were tested positive on their first screening. Ninety-four patients (78.3%) of those attended the ENT department for a first rescreening. Thirty-four patients (0.59% of total) were tested positive again and referred to the regional screening center. Out of the 27 patients who attended the second rescreening, four (0.07% of the total) were ultimately diagnosed with hearing impairment. CONCLUSION: Our study found that newborn hearing screening (NHS) in our region achieved a high compliance rate of 98.8% for initial screenings in 2020. However, challenges remain in the rescreening process due to data management issues, inter-regional cooperation, and public awareness. The recent implementation of mandatory screenings, updated guidelines, and a centralized database is expected to enhance the effectiveness of NHS. Further research is needed to evaluate these improvements.

<b>Aim:</b> The aim was to compare hearing loss between men and women over 65 in pure tone audiometry and to evaluate the sensitivity of the abbreviated version of the Hearing Handicap Inventory (HHIE-S). This questionnaire highlights hearing handicaps in understanding speech. </br></br><b> Materials and Methods:</b> The data was collected in the years 2011-2015 from respondents above 18 years of age using a standar-dized HHIE-S questionnaire and specialized tests. The cohort was divided into groups based on the severity of hearing loss in the better ear according to the World Health Organization (WHO) as measured by tone threshold audiometry at 500 Hertz (Hz), 1000 Hz, 2000 Hz and 4000 Hz. </br></br> <b> Results:</b> Of the 7070 people (61.8% female and 38.2% male), 68.93% had hearing impairment. Most people had a slight he-aring loss. Based on HHIE-S, 56.94% reported impaired hearing. A statistically significant difference was found between the genders, but according to HHIE-S, females with impaired hearing were not statistically significantly more numerous than males. The diagnostic sensitivity of the HHIE-S was assessed in particular by its sensitivity (75.43%) and specificity (82.53%). The probability that a person has a hearing impairment when the HHIE-S test is positive is 90.21%. </br></br> <b> Conclusions:</b> The HHIE-S is fast, inexpensive and short, and can be included as a screening test for hearing impairment in ca-ring for the elderly. Even a minor hearing impairment can be a significant handicap in elderly patients by restricting not only social interactions but also weakening mental functioning.

PURPOSE: This study aimed to determine hearing thresholds in an otologically normal population without occupational noise exposure aged 18 to 64 years using extended high-frequency audiometry (EHFA). METHODS: Individuals from the general population who have never had hearing problems and whose job was not associated with noise exposure were included in the study and classified by age into 5 categories: 18-24 and, further, by 10 years of age. Each of these groups was further divided according to gender. All subjects underwent tympanometry, conventional pure-tone audiometry within the 0.125-8 kHz range, and extended high-frequency audiometry within the 9-16 kHz range, performed according to the standards. The significance level for statistical testing was set at 5%. RESULTS: Here, we established hearing thresholds in an otologically healthy population within the extended high-frequency (EHF) range (9-16 kHz). We found the EHFA to be a highly sensitive method for early detection of hearing loss, with hearing thresholds decreasing as soon as 35 years of age. In males, the hearing thresholds grew with age more rapidly than in women. The ability to respond at EHF gradually decreased with age and increasing frequency. CONCLUSION: Our results can help improve the knowledge of EHF hearing thresholds for individual sexes and age groups. So far, the standard 7029:2017 is not binding and, moreover, it only reaches up to the frequency of 12.5 kHz. EHFA is a highly sensitive method for the evaluation of hearing loss depending on age and sex.

PURPOSE: Remote microphone systems improve intelligibility in difficult conditions when the performance of hearing aids/cochlear implants is insufficient. The purpose of this study was to explore parents' experiences with remote microphone systems for their children with hearing loss and to determine the advantages and disadvantages as perceived by parents. MATERIALS AND METHODS: Data were collected by means of semi-structured interviews with parents of children with moderate to profound bilateral hearing loss (2-19 years old). The open coding method and thematic analysis were used. The final sample consisted of 19 mothers and 9 fathers who had experience with remote microphone systems. RESULTS: Parents listed the advantages of remote microphone systems for their child, for themselves and for other carers, such as better hearing and understanding, a life more similar to that of their peers without hearing loss, safety in road traffic, lower fatigue, vocabulary acquisition, better school results. Some limitations were identified, namely low benefits, technical issues and a reluctance to use the device by children or teachers. CONCLUSIONS: It is crucial to provide parents with information about assistive devices and the consequences of limited access to hearing speech. Professionals should motivate parents, children and teachers to use remote microphone systems even in situations when the benefit may not be obvious if there is a potential benefit for the child. UNLABELLED: IMPLICATIONS FOR REHABILITATIONThe main advantages of remote microphone systems perceived by parents are better hearing and understanding, a life more similar to peers without hearing loss, safety in traffic, lower fatigue, vocabulary acquisition and better school results.The main disadvantages are for parents: persisting hearing problems, low benefits, technical issues and a reluctance to use the device by children or teachers.Sufficient and accurate information is needed about remote microphone systems, but also about the consequences of hearing loss in general.The possibility to try wireless devices before buying and troubleshooting help is appreciated.

OBJECTIVES: To evaluate the hearing benefit, advantages, and disadvantages in a series of children using a new, nonimplantable, pressure-free, adhesive bone conduction hearing aid. METHODS: Seventeen children were included in the study. 5 children suffered from bilateral conductive hearing loss (CHL), 6 children with unilateral CHL and 6 children with unilateral sensorineural hearing loss. An audiological tests were provide. Additionally, sound quality (SSQ10) and quality of life (AQoL-6D) were assessed using questionnaires. RESULTS: The average value of speech audiometry with bubble noise in children with SNHL is 21.33 (±5.72) dB HL with the device and 27.67 (±4.59) dB HL without the device, which is a statistically significant gain (p = 0.027). The analysis showed the average value of hearing threshold in sound field in the group of children with CHL supported 20.23 (±16.84) dB HL and not supported 33.52 (±27.27) by the hearing aid for bone conduction, which i a statistically significant gain (p = 0.008). The average value of speech audiometry is 23.45 (±14.45) dB HL with the device and 37.27 (±26.65) dB HL without the device, which is a statistically significant gain (p = 0.012). The average value of speech audiometry with bubble noise is 30.55 (±10.03) dB HL with the device and 45.45 (±18.41) dB HL without the device, which is a statistically significant gain (p = 0.008). No patient referred pain or irritation. CONCLUSION: This new device for bone conduction show a hearing benefit for a paediatric patient, without any concomitant aesthetic and other complications.

The WHO considers hearing loss to be a major global problem. A literature search was conducted to see whether high-frequency audiometry (HFA) could be used for the early detection of hearing loss. A further aim was to see whether any differences exist in the hearing threshold using conventional audiometry (CA) and HFA in workers of different age groups exposed to workplace noise. Our search of electronic databases yielded a total of 5938 scientific papers. The inclusion criteria were the keywords "high frequency" and "audiometry" appearing anywhere in the article and the participation of unexposed people or a group exposed to workplace noise. Fifteen studies met these conditions; the sample size varied (51-645 people), and the age range of the people studied was 5-90 years. Commercial high-frequency audiometers and high-frequency headphones were used. In populations unexposed to workplace noise, significantly higher thresholds of 14-16 kHz were found. In populations with exposure to workplace noise, significantly higher statistical thresholds were found for the exposed group (EG) compared with the control group (CG) at frequencies of 9-18 kHz, especially at 16 kHz. The studies also showed higher hearing thresholds of 10-16 kHz in respondents aged under 31 years following the use of personal listening devices (PLDs) for longer than 5 years. The effect of noise-induced hearing loss (NIHL) first became apparent for HFA rather than CA. However, normative data have not yet been collected. Therefore, it is necessary to establish a uniform evaluation protocol accounting for age, sex, comorbidities and exposures, as well as for younger respondents using PLDs.

BACKGROUND: Age-related hearing loss is the third most common reason for disability in the world and has a significant impact on quality of life (QoL) amongst older adults. OBJECTIVE: To determine how the QoL assessment in older-person-specific domains differs between older men and women with age-related hearing loss before and after hearing-aid fittings. METHODS: The present study was carried out with 105 hearing-impaired outpatients (aged ≥ 60 years) before and after hearing-aid fittings at the University Hospital Olomouc, Czech Republic. The instrument used was the World Health Organization Quality of Life-Older Adults module (WHOQOL-Old). It was completed before hearing-aid fittings and after the first check-up hearing-aid adjustment. The Wilcoxon paired test multiple logistic regression was used to evaluate changes in the QoL after hearing-aid fittings. The distributions of men a women into three subgroups, improved, unchanged, and worsened in each domain, were compared using Fisher's exact test. RESULTS: A significant QoL improvement when fitting a hearing-aid in the area of Sensory abilities was confirmed in both men and women (p < 0.001). In Autonomy, a significant improvement was recorded only amongst men (p = 0.010). In Past, present and future activities and Social participation, a significant improvement was only recorded amongst women (p = 0.029; p = 0.001). Significant differences were revealed between men and women in changes for Sensory Abilities (p = 0.019), Social Participation (p = 0.036) and Intimacy (p = 0.002). CONCLUSIONS: The findings of this study suggest that there are gender differences in QoL improvement amongst people with age-related hearing loss after hearing-aid fitting.

PURPOSE: This study aimed to investigate whether hearing aids use is associated with improvement of older-person-specific QOL and whether social interactions modify the association. METHODS: The WHOQOL-OLD questionnaire was answered by 105 older adults aged 60 to 90 years who were newly fitted hearing aids on the day of fitting and at 2 - 6 months afterward. The associations between the daily hours of hearing aid usage and social relations with changes in the WHOQOL-OLD total score after hearing aids fitting were estimated adjusting for possible confounders. RESULTS: Older persons with hearing loss experienced significant increases in WHOQOL-OLD total score after hearing aid fitting. Regular use of hearing aid was associated with a greater increase in the total score. The combined categorical variable of social relations and hearing aid usage revealed no separate effects of these two variables, but a combined effect; only those with frequent social interactions who used their hearing aid regularly had a significantly greater increase in WHOQOL-OLD total score. CONCLUSION: This study's findings indicate that hearing aid fitting may be associated with a subsequent improvement in older-person-specific QOL by improvements in hearing due to the hearing aid, and possibly enhanced communication opportunities.
