OBJECTIVE: The bone-anchored hearing aid (BAHA) Attract is a transcutaneous bone conduction hearing aid that uses magnetic coupling to enable sound conduction. We report the first case of skin necrosis associated with the BAHA Attract and perform a literature review of soft tissue complications related to the device. PATIENT: A single patient who was found to develop skin necrosis 2 weeks after being fitted for the BAHA Attract speech processor. INTERVENTION: After the patient developed skin necrosis from the device, she was advised to immediately discontinue use of the Attract to allow complete wound healing, upon which the Attract was successfully converted to a percutaneous BAHA...

Bone-anchored hearing aids are an established means of managing both single-sided and bilateral conductive or mixed hearing loss. Magnetic bone conduction hearing implants have been designed to provide an alternative bone conduction system to the existing aids which couple to a traditional percutaneous abutment. The BAHA(®) Attract (Cochlear Bone Anchored Solutions AB. Mölnlycke, Sweden) system, which has been reviewed, uses an osseointegrated titanium implant coupled to an implantable magnet.

BACKGROUND: The rehabilitation of patients with single-sided deafness (SSD) or asymmetric hearing loss can be achieved with conventional (bilateral) contralateral routing of signals ((Bi)CROS) hearing aids ((Bi)CROS-HA, (Bi)CROS), bone-anchored hearing systems (BAHS) or cochlear implants (CI). To date, only small case series have been published on treatment outcomes in SSD patients after CI surgery and there are only a few comparative studies evaluating rehabilitation outcomes. OBJECTIVE: The aim of this study was to provide evidence of successful treatment of SSD and asymmetric hearing loss with a CI compared to the untreated monaural hearing condition and the BAHS and (Bi)CROS treatment options in a large number of patients...

BACKGROUND: Assessment of the internal auditory canal (IAC) and the cochlea is of central importance in neurotology. The artefacts and visibility of the different types of active auditory implants in MRI vary, due to their specific ferromagnetic components. Knowledge of the size of MRI artefacts and the options for handling these is important for the auditory rehabilitation of specific diseases (e. g., vestibular schwannoma). METHODS: The current paper is a literature review RESULTS: MRI assessment of the IAC and cochlea after surgical placement of an active auditory implant is feasible only with a percutaneous bone-anchored hearing aid (BAHA, Ponto)...

Bone-anchored hearing aids are external devices attached to the skull via a titanium implant, and can be used for multiple types of hearing loss. Traditionally, osseointegrated implants have been coupled to the external processor with a percutaneous abutment, but more recently, a fully implanted, transcutaneous magnet-based system has become available. Skin reactions from the percutaneous portion are a common complication that can prevent use of the device during critical windows of language development and learning in children...

OBJECTIVE: Current bone-anchored hearing aid (BAHA) guidelines recommend placement of the titanium implant 5 to 7 cm posterior to the ear canal. Previous studies show that bone conducted hearing is maximized the closer the transducer is to the cochlea. We aim to investigate the position of the sigmoid sinus with respect to BAHA implants to determine whether they may be safely placed closer to the ear canal in patients with chronic ear disease, enhancing the amplification available to the patient...

This study presents the Advanced System for Implant Stability Testing (ASIST) which provides a non-invasive, quantitative measure of the stability of percutaneous implants used for craniofacial rehabilitation such as bone anchored hearing aids or dental implants. The ASIST uses an impact technique coupled with an analytical model which allows the measure to be independent of the system components. This paper presents a laboratory evaluation of the ASIST for the Oticon Medical Ponto and the Cochlear Baha Connect bone anchored hearing aid (BAHA) systems...

HYPOTHESIS: The transcutaneous bone conduction implant (BCI) is compared with bone-anchored hearing aids (BAHAs) under the hypothesis that the BCI can give similar rehabilitation from an audiological as well as patient-related point of view. BACKGROUND: Patients suffering from conductive and mixed hearing losses can often benefit more from rehabilitation using bone conduction devices (BCDs) rather than conventional air conduction devices. The most widely used BCD is the percutaneous BAHA, with a permanent skin-penetrating abutment...

Transcranial attenuation (TA) of bone-conducted sound has a high degree of variability by frequency and subject, which may play a role in the objective benefit of individuals with single-sided deafness (SSD) treated with a bone-anchored implant (BAI). This study sought to determine whether TA is predictive of benefit in individuals with SSD who receive a BAI. Adult, English-speaking patients with unilateral profound sensorineural hearing loss who underwent a BAI evaluation were included for study. Absolute TA values were consistent with previously published reports...

OBJECTIVE: Bone-anchored hearing aid has been shown to be effective in hearing rehabilitation for conductive loss or single-sided deafness. Current FDA guidelines allow implantation in patients over 5 years old. This guideline is at least partially due to concern for thickness of bone stock at the implant site. We aim to investigate whether temporal bone thickness should be a deterrent to implantation in those younger than five. STUDY DESIGN: A retrospective review of high-resolution temporal bone computed tomographies (CTs) comparing measurements between ears with chronic disease and controls...

In adaptive Speech Reception Threshold (SRT) tests used in the audiological clinic, speech is presented at signal to noise ratios (SNRs) that are lower than those generally encountered in real-life communication situations. At higher, ecologically valid SNRs, however, SRTs are insensitive to changes in hearing aid signal processing that may be of benefit to listeners who are hard of hearing. Previous studies conducted in Swedish using the Sentence-final Word Identification and Recall test (SWIR) have indicated that at such SNRs, the ability to recall spoken words may be a more informative measure...
