[Ab] Resumo:OBJECTIVE: To delineate the auditory functional improvement and peri-operative outcomes of the Sophono™ transcutaneous bone conduction device. METHODS: Eligible articles presenting patients implanted with the Sophono™ were identified through a comprehensive search of PubMed and Embase electronic databases. All relevant articles were reviewed to justify inclusion independently by 2 authors. Studies that successfully passed critical appraisal for directness of evidence and risk of bias were included. RESULTS: From a total of 125 articles, 8 studies encompassing 86 patients using 99 implants were selected. Most patients (79.1%) were children. Ear atresia (67.5%) was the most frequently reported indication for Sophono™ implantation. Overall pure tone average auditory improvement was 31.10 (±8.29) decibel. During a mean follow-up time of 12.48 months, 25 patients (29%) presented with post-operative complications from which 3 were deemed as serious implant-related adverse events (3.5%). CONCLUSIONS: The Sophono™ transcutaneous bone conduction device shows promising functional improvement, no intra-operative complications and minor post-operative skin related complications. If suitable, the device could be a proposed solution for the rehabilitation of hearing in children meeting eligibility criteria. A wearing schedule must be implemented in order to reduce magnet-related skin complications.

[Ab] Resumo:BACKGROUND: Low frequency magnetic field, inducing electrical field (Ein) inside conductive structures may directly affect the human body, e.g., by electrostimulation in the nervous system. In addition, the spatial distribution and level of Ein are disturbed in tissues neighbouring the medical implant. MATERIAL AND METHODS: Numerical models of magneto-therapeutic applicator (emitting sinusoidal magnetic field of frequency 100 Hz) and the user of hearing implant (based on bone conduction: Bonebridge type - IS-BB or BAHA (bone anchorde hearing aid) type - IS-BAHA) were worked out. Values of Ein were analyzed in the model of the implant user's head, e.g., physiotherapist, placed next to the applicator. RESULTS: It was demonstrated that the use of IS-BB or IS-BAHA makes electromagnetic hazards significantly higher (up to 4-fold) compared to the person without implant exposed to magnetic field heterogeneous in space. Hazards for IS-BAHA users are higher than those for IS-BB users. It was found that applying the principles of directive 2013/35/EU, at exposure to magnetic field below exposure limits the direct biophysical effects of exposure in hearing prosthesis users may exceed relevant limits. Whereas applying principles and limits set up by Polish labor law or the International Commission on Non-Ionizing Radiation Protection (ICNIRP) guidelines, the compliance with the exposure limits also ensures the compliance with relevant limits of electric field induced in the body of hearing implant user. CONCLUSIONS: It is necessary to assess individually electromagnetic hazard concerning hearing implant users bearing in mind significantly higher hazards to them compared to person without implant or differences between levels of hazards faced by users of implants of various structural or technological solutions.

[Ab] Resumo:BACKGROUND: The percutaneous osseointegrated bone conduction device can be associated with more soft tissue complications when compared to the magnetic transcutaneous osseointegrated bone conduction device. This study aimed to determine whether fewer soft tissue complications may result in the transcutaneous osseointegrated bone conduction device being a lower cost option in hearing rehabilitation. METHODS: This retrospective case note review included adult patients who underwent implantation with the transcutaneous Cochlear Attract (n = 22) or percutaneous Cochlear DermaLock (n = 25) bone-anchored hearing aids between September 2013 and December 2014. The number of post-operative clinic appointments, complications and treatments undertaken, and calculated cost average, were compared between the two groups. RESULTS: Although the transcutaneous device was slightly more expensive than the percutaneous device, the percutaneous device was associated with a greater number of soft tissue complications and, as a result, the percutaneous device had significantly higher follow-up costs in the first six months following surgery. CONCLUSION: The transcutaneous osseointegrated bone conduction device may represent a more cost-effective method of hearing rehabilitation compared to the percutaneous osseointegrated bone conduction device.

[Ab] Resumo:BACKGROUND: Otosclerosis is a cause of 5-9% of all hearing loss. The most effective treatment of otoslerosis is stapedotomy. AIM: The aim of this study was to evaluate the results of otosclerosis surgical treatment and to examine the impact of disease stage, time of the signs, age and sex on the results. MATERIAL AND METHODS: 105 patients who underwent operation due to otosclerosis at the Department of Otolaryngology University Hospital in Zabrze at the age of 18-65 were analyzed. In 25 patients stapedotomy was bilateral. 130 cases of treated ears were included in the statistical analysis. The state of hearing after operation was evaluated with regard to guidance of Hearing and Balance Committee of American Academy of Otolaryngology - Head and Neck Surgery and with consideration of suggestions made by European Academy of Otolaryngology and Neurootology. Mean values of bone and air conduction, air bone gap before, one year after treatment, and at least 4 years after surgery were compared. The influence of stage of the disease in terms of Shambaugh index, lasting of signs, age and sex were evaluated with regard to change of mean hearing loss according to Bell Telephone Laboratories. RESULTS: On the basis of hearing examination evaluating improvement in air and bone conduction and reduction of cochlear reserve, very good and good treatment results were obtained in over 90% of patients in short and long term observations. No influence of disease stage, time of signs lasting, age and sex on the results of treatment - with regard to change in mean hearing loss was shown.

[Ab] Resumo:OBJECTIVES: Children with Idiopathic Nephrotic Syndrome (INS) are at risk of hearing loss due to the adverse impact of medications and related immunological and genetic factors on both cochlea and kidney. So this work was planned to evaluate hearing status in children with INS and to clarify the possible associated risk factors by interpreting the clinical and laboratory profiles of those children. METHODS: Ninety children with INS aged 5-14 years [30 patients with steroid-sensitive nephrotic syndrome (SSNS), 30 patients with steroid dependent/frequently relapsing nephrotic syndrome (SDNS/FRNS), and 30 patients with steroid-resistant nephrotic syndrome (SRNS)], and 90 age and sex matched normal controls were enrolled into this study. Laboratory measurements of serum calcium, creatinine, cholesterol, blood urea and other relevant investigations were done. Pure tone audiometry was done with the sensory-neural hearing loss (SNHL) diagnosed when the level bone conduction was >20 dB and the difference in air to the bone gap was <15 dB. RESULTS: 40% children with INS had SNHL, mostly of mild degree HL and primarily occurred at the lower frequencies. A highly significant statistical difference between controls and various types of nephrotic syndrome regarding pure tone audiometry measurements at frequencies 250, 500, 1000 Hz, whereas insignificant difference interpreting pure tone audiometry measurements in 2000, 4000 and 8000 Hz. CONCLUSIONS: Children with different phenotypes of nephrotic syndrome are at risk of sensorineural hearing impairment. The hazards associated with this impairment were higher blood pressure, hypercholesterolemia, hypoalbuminemia, and hypocalcemia.

[Ti] Título:The effects of distractor sounds presented through bone conduction headphones on the localization of critical environmental sounds.

[Ab] Resumo:Bone conduction headphones are devices that transmit sound through the bones of a listener's head rather than through the air in their outer ear. They have been marketed as a safer way to enjoy audio content while walking, jogging, or cycling. However, listening to distracting sounds over bone conduction may still disrupt a listener's awareness of their auditory environment. The present study investigated the nature of this interference with the faculty of sound source localization-a key prerequisite for generating situation awareness through audio. Participants sat in the middle of a circle of loudspeakers and listened for target sounds played from different directions. Each time they heard a sound, they responded by indicating what direction they judged the sound to have come from. Meanwhile, participants listened to distractor sounds played through bone conduction headphones. Participants heard (1) no distractor sounds, (2) a spoken story that they were instructed to ignore, and (3) the same spoken story that they were instructed to attend to. For conditions (2) and (3), some participants heard a version of the story with background music, while others heard the spoken story without the music. Participants had greater localization error in the distractor-present conditions. Additionally, participants who heard the spoken story with music exhibited greater localization error. However, there was no effect of whether participants ignored or attended to distractors. This pattern was attributed to masking effects, and was more pronounced for narrow-band targets compared to broadband targets. Post-hoc analyses found evidence of a 'pulling' effect, in which localization judgments were systematically biased toward the apparent direction of the bone conducted distractors. These results indicate that using bone conduction headphones can be expected to cause a decline in a person's awareness of their environment, in a subtle way that a jogger or cyclist might not be actively aware of, even if their attention is directed to the environment and environmental sounds are readily detectible.

[Ab] Resumo:INTRODUCTION: Baha Attract is a new transcutaneous bone-conduction hearing aid, which is more preferable in childhood than the conventional percutaneous systems. AIM: Our aim was to demonstrate the possibilities of application in childhood. METHOD: Eight children have undergone surgeries (mean age of 13.2 ± 3.2 years; "posterosuperior" incision technique, 5 mm implants). The thickness of the skull bone was determined in 72 children (1-8 years old) at the recommended implant site, based on CT scans. RESULTS: The average duration of surgeries was 30 minutes. There were no intra- and postoperative complications observed. Sound processors were fitted at the postoperative 4th week. Hearing measurements proved 51.58±11.22SD dBHL gain in warble tone thresholds, and 43.3 ± 16.02 SD dB in speech discrimination thresholds. The skull bone thickness was measured as 3.39 ± 1.05 SD mm. CONCLUSION: The Baha Attract system is a new tool for hearing rehabilitation in pediatric population. Preoperative CT provides valuable knowledge about skull bone thickness. Orv.

[Ab] Resumo:OBJECTIVE: The aim of this study was to review the outcomes of Bone Anchored Hearing Aid (BAHA ) Attract implantation in a cohort of paediatric patients. METHODS: Prospective data collection and case review were undertaken in a paediatric tertiary referral centre. We have included patients under the age of 16 years with unilateral or bilateral hearing loss that met the criteria for BAHA Attract implantation. The main outcome measures were surgical complications and Patient Reported Outcomes including the 'Speech, Spatial and Qualities of Hearing scale' (SSQ-12) and 'Qualitative Feedback for BAHA 5 Hearing Aids'. RESULTS: Twenty-five paediatric patients were implanted with the BAHA Attract between June 2014 and July 2016. Nine of them had a conversion from a percutaneous Bone Conduction Hearing Device (BCHD). Four children had minor skin problems that settled with conservative measures. Two children with a previous percutaneous BCHD developed skin dehiscence over the magnet after conversion to the transcutaneous version. The SSQ-12 was completed by 6 children and an improvement of 22% was noted between the unaided and aided condition. The patients and their parents were generally satisfied with the BAHA Attract. CONCLUSIONS: The BAHA Attract offers a good solution for hearing rehabilitation in appropriately selected and counseled patients. The complication rate was low for primary surgery but higher in cases of conversion from a percutaneous device. Large, prospective data is needed to evaluate the relative risks and benefits of this BCHD.

[Ab] Resumo:OBJECTIVES: To systematically review the literature on the audiological and/or quality of life benefits of a bone conduction hearing aid (BCHA) in children with congenital unilateral conductive or sensorineural deafness. METHODS: A systematic search was performed according to the PRISMA guidelines using the PubMed, Medline, and Embase databases. Data were collected on the following outcomes of interest: speech reception threshold, speech discrimination, sound localization, and quality of life measures. Given the heterogeneity of the data for quantitative analysis, the results are qualitatively summarized. RESULTS: Eight studies were included in the review. Four studies examined the audiological outcomes associated with bone conduction hearing aid implantation. There was a consistent gain in speech reception thresholds and speech discrimination, especially in noisy environments. Results pertaining to sound localization was inconsistent. The studies that examined quality of life measures reported a high usage rate of BCHAs among children. Quality of life improvements are reported with suggested benefit in the subdomain of learning. CONCLUSION: Given the potential benefits of a BCHA, along with the fact that it can be safely trialed using a headband, it is reasonable to trial a BCHA in children with congenital unilateral deafness. Should the trial offer audiological and/or quality of life benefits for the individual child, then BCHA implantation can be considered.

[Ab] Resumo:BACKGROUND: Otosclerosis is a common cause of progressive hearing impairment that causes fixation of the stapes. Surgical intervention is the preferred treatment approach to ameliorate the conductive hearing loss associated with stapedial otosclerosis. However, given that it is a difficult and delicate procedure, the surgery may fail for a number of reasons. Therefore, it is very important to evaluate the success rate of the surgical approach used in each regional center. OBJECTIVE: To examine the effectiveness of stapedotomy in improving hearing sensitivity for otosclerotic patients at King Abdul Aziz University Hospital in Riyadh. DESIGN: Retrospective chart review with an analysis of pre- and postoperative surgical treatment. SETTING: Tertiary referral otolaryngology clinic. PATIENTS AND METHODS: All cases who underwent stapedotomy between 1997 and 2009 were retrospectively reviewed. Preoperative and postoperative audiometric assessments were conducted using conventional pure tone audiometry. Differences were analyzed by two-way repeated measures ANOVA. MAIN OUTCOME MEASURE(S): Pre- and postoperative pure tone thresholds for air and bone conduction. RESULT: Fifty-three patients underwent stapedotomy. Stapedotomy yielded significant improvements in mean (SD) postoperative air-conduction thresholds of about 18.7 (11.7) dB (P < .0001) and mean (SD) post.operative bone-conduction thresholds of about 2 (7.2) dB (P < .05). Additionally, a significant correlation was found between improvement in air-conduction thresholds and the size of preoperatve air-bone gap (P < .01) About 70%of patients achieved an air-bone gap of 20 dB or better. None of the cases examined in this study exhibited sensorineural hearing loss or adverse complications following stapedotomy. CONCLUSIONS: Stapedotomy is a safe and effective treatment option for patients with otosclerosis. Given that the majority of participants in this study exhibited mixed hearing loss preoperatively, the results further suggest that stapedotomy can also be effective in improving thresholds for these patients. LIMITATIONS: The sample size was relatively small.
