This report provides the first short-term followup data on the Ponto bone-anchored hearing implant from our tertiary referral centre. Thirty-one consecutive patients with a mean age of 51 years who received the implant between October 2010 and December 2011 were included retrospectively in this study. Implant loss, skin reactions around the implant (according to Holgers' grading system), revision surgery, and abutment replacements were retrospectively gathered from the patients' files as objective outcome measures. To obtain information on subjective patient satisfaction, the Glasgow Benefit Inventory (GBI) was used. The mean follow-up period was 16.9 months (range 12.1-25.2 months). One implant was lost. Over a total of 94 follow-up visits, 21 skin reactions were observed in 16 patients: Holgers grade 1 (slight redness, no need for treatment) in 18.1 % of the visits,and grade 2 (redness and moist, needing conservative treatment) in 4.3 % of the visits. Four 6-mm abutments (12.9 %) were replaced for a 9-mm abutment during the follow-up period, of which one (3.2 %) was in combination with revision surgery. In one patient keloid formation around the implant was observed. The GBI revealed a moderate subjective benefit. The short-term results with these percutaneous implants demonstrate a clinically stable implant with a low percentage of skin reactions that require treatment. Longterm, prospective follow-up data are needed to draw firmer conclusions.

Introduction: The bone-anchored hearing system has become the most viable treatment option for subjects with conductive or mixed hearing loss, who are unable to benefit from conventional hearing aids or middle ear surgery. Objective: To compare the surgical and audiological outcomes between the minimally-invasive Ponto surgery and a linear incision with soft tissue preservation techniques in bone-anchored hearing system recipients. Methods: A retrospective study was carried out from January 2017 to June 2018. Forty-two adult patients eligible for unilateral bone-anchored hearing system surgery with the Ponto system were included in the study. The implant and abutment lengths used varied from 3 to 4 mm and from 6 to 14 mm, according to the bone and skin thickness of the participants, respectively. Results: Twenty-two surgeries were performed using the minimally invasive Ponto surgery technique (52.4%) and 20 (47.6%) using the linear incision. The mean age of the subjects implanted with minimally invasive Ponto surgery and linear incision techniques were 42.0 and 33.3 years old, respectively. Ten male (45,5%) and 14 (70%) female patients were implanted using minimally

Conclusion Using a second bone anchored hearing implant (BAHI) mounted on a testband in unilaterally implanted BAHI users to test its potential advantage pre-operatively under-estimates the advantage of two BAHIs placed on two implants. Objectives To investigate how well speech understanding with a second BAHI mounted on a testband approaches the benefit of bilaterally implanted BAHIs. Method Prospective study with 16 BAHI users. Eight were implanted unilaterally (group A) and eight were implanted bilaterally (group B). Aided speech understanding was measured. Speech was presented from the front and noise came either from the left, right, or from the front in two conditions for group A (with one BAHI, and with two BAHIs, where the second device was mounted on a testband) and in three conditions for group B (same two conditions as group A, and in addition with both BAHIs mounted on implants). Results Speech understanding in noise improved with the additional device for noise from the...

Introduction The bone-anchored hearing implant system (BAHS) is an effective amplification system that transmits the sounds received by an external operating system to the inner ear by bypassing the middle ear placed in the temporal bone. Objective This study compares the results of patients who underwent bone-anchored hearing implant system (BAHS) surgery using two different surgical methods in terms of preoperative and postoperative complications, surgical time, audiological findings, and patient satisfaction. Methods The results of 22 patients who underwent BAHS were evaluated retrospectively from video records and audiological results, The Turkish Version of the Glasgow Benefit Inventory (GBI) questionnaire were evaluated. Two different surgical approaches were used for implantation: the linear incision technique (n = 9) and the punch technique (n = 13). Results Mean surgical durations were 9.67 ± 2.85 and 47.65 ± 6.13 minutes for Groups A and B, respectively, and these were sig...
Assessment Protocol for Candidates for Bone-Anchored Hearing Devices
International Archives of Otorhinolaryngology
Introduction The technology regarding bone-anchored hearing devices has been advancing. Nevertheless, complications are still often reported, which can impair treatment adherence and lead to discontinuation of use. There is a lack of studies conducted in tropical countries, where complications can be even greater, as well as standardized protocols for selection, indication and evaluation. Objective To characterize implanted patients from a Brazilian public institution and describe the medical and audiological assessment protocols to which they were submitted during the selection process and in the follow-up after surgery. Method An observational, cross-sectional study evaluating the medical records of patients with hearing loss and ear malformations and describing the care protocol through which they were treated. Results The medical records of 15 patients were reviewed: 6 received transcutaneous implants, and 9, percutaneous implants; 9 patients reported some type of skin lesion, 2...

Single-sided deafness (SSD) represents one of the most difficult audiological conditions to rehabilitate. The aim of this prospective study was to evaluate the audiological benefits and quality of life of patients affected by SSD who had previously been users of the Alpha 1® when upgrading them to the Sophono Alpha 2® external processor (Boulder, Colo., USA). Nine patients were included in the study. They underwent physical examination, free-field speech audiometry at 40 and 60 dB, a hearing-in-noise test (Hirsch's test and the squelch test), the Glasgow Benefit Inventory (GBI) questionnaire, and a specific questionnaire on patient satisfaction with Alpha 1. Afterwards, the Alpha 2 external processor was delivered to all patients, and the above-mentioned protocol was repeated after 1 month with the Alpha 2. A statistically significant improvement was found in the speech discrimination score at 40 dB and in the squelch test when using the Alpha 2 external processor compared to th...

Purpose To investigate 2-year post-operative hearing performance, safety, and patient-reported outcomes of hearing-impaired adults treated with the Osia ® 2 System, an active osseointegrated bone-conduction hearing implant that uses piezoelectric technology. Methods A prospective, multicenter, open-label, single-arm, within-subject clinical study conducted at three tertiary referral clinical centers located in Melbourne, Sydney and Hong Kong. Twenty adult recipients of the Osia 2 System were enrolled and followed up between 12 and 24 months post-implantation: 17 with mixed or conductive hearing loss and 3 with single-sided sensorineural deafness. Safety data, audiological thresholds, speech recognition thresholds in noise, and patient-reported outcomes were collected and evaluated. In addition, pre-and 6-month post-implantation data were collected retrospectively for this recipient cohort enrolled into the earlier study (ClinicalTrials.gov NCT04041700). Results Between 6-and 24-month follow-up, there was no statistically significant change in free-field hearing thresholds or speech reception thresholds in noise (p = > 0.05), indicating that aided improvements were maintained up to 24 months of follow-up. Furthermore, improvements in health-related quality of life and daily hearing ability, as well as clinical and subjective measures of hearing benefit remained stable over the 24-month period. No serious adverse events were reported during extended follow-up. Conclusions These study results provide further evidence to support the longer term clinical safety, hearing performance, and patient-related benefits of the Osia 2 System in patients with either a conductive hearing loss, mixed hearing loss, or single-sided sensorineural deafness.

The bone-anchored hearing aid (BAHA) is a bone conduction hearing device that transmits sound directly into the inner ear. It is mainly used in patients with conductive hearing loss associated with aural atresia, but it is also used in those with mixed and sensorineural hearing loss. To review the main indications for BAHA, to analyze the audiometric results and its benefits for patients and compare them with other treatment modalities, and to compare the literature data with our sample of 13 patients. The research was performed using a database covering works in English, Spanish, and Portuguese, with no limitations in the years when the procedures were performed. We compared the literature data with our results for the 13 patients who underwent BAHA implantation between the years 2000 and 2009. Most of the studies showed that BAHA has great advantages over reconstructive surgery in terms of hearing results, complications, and disease recurrence. The postoperative results for ou...
Bilateral Bone‐Anchored Hearing Aids (BAHAs): An Audiometric Evaluation
The Laryngoscope, 2004
Objectives Since the technique to implant bone‐anchored hearing aids (BAHAs) with the use of osseointegrated implants was developed in 1977, more than 15,000 patients have been fitted with BAHAs worldwide. Although the majority have bilateral hearing loss, they are primarily fitted unilaterally. The main objective of this study was to reveal benefits and drawbacks of bilateral fitting of BAHAs in patients with symmetric or slight asymmetric bone‐conduction thresholds. The possible effects were divided into three categories: hearing thresholds, directional hearing, and binaural hearing.Study Design Prospective study of 12 patients with bilateral BAHAs.Methods Baseline audiometry, directional hearing, speech reception thresholds in quiet and in noise, and binaural masking level difference were tested when BAHAs were fitted unilaterally and bilaterally.Results Eleven of the 12 patients used bilateral BAHAs on a daily basis. Tests performed in the study show a significant improvement in...
