Bone anchored hearing aid

OBJECTIVES: There have been significant surgical and technological advances in bone-anchored hearing aid (BAHA) design, function, and implantation technique, but peri-implant skin complications remain the most frequent complication. The most important aspect in dealing with cutaneous complications is to identify the type of cutaneous lesion. Although Holger's Classification has been an extremely useful clinical tool, this grading system has been shown to be unsuitable for some cases. We therefore propose a new consistent and easy assessment classification of cutaneous complications associated with BAHA...

PURPOSE: Due to smaller bone thickness, young children with conductive or mixed hearing loss or single-sided deafness were previously most commonly treated with a percutaneous osseointegrated bone-anchored hearing aid (BAHA) or an active middle-ear implant. While the BAHA increases the risk of implant infections, skin infection, overgrowth of the screw or involvement of the implant in head trauma, middle-ear implant surgery involves manipulation of the ossicles with possible risk of surgical trauma...

PURPOSE: The study evaluated if there were differences between two types of bone-anchored hearing aids (BAHA), percutaneous vs transcutaneous implants in terms of audiological and psychosocial outcomes. METHODS: Eleven patients were enrolled. Inclusion criteria were: patients with conductive or mixed hearing loss in the implanted ear with a bone conduction pure-tone average (BC PTA) of the hearing threshold at 500, 1000, 2000, and 3000 Hz ≤ 55 dB HL, aged > 5 years...

OBJECTIVE: The purpose of this study was to evaluate the functional and patient-reported outcomes, and their correlation, after percutaneous bone-anchored hearing aid (BAHA) implantation. METHODS: A prospective study was conducted between January 2018 and December 2020 in a tertiary care center. All adult patients who were implanted with a percutaneous BAHA device during this evaluation period were included in the study. Complete auditory function and patients reported outcome measures (PROMs) were assessed in the preoperative period and 6 months after the implant activation...

Untreated conductive and mixed hearing losses as a result of middle ear pathology or congenital ear malformations can lead to poor speech, language and academic outcomes in children. Lack of access to centralised hearing healthcare in resource-constrained environments limits opportunities for children with hearing loss. Red Cross War Memorial Children's Hospital (RCWMCH) is one of only two dedicated paediatric hospitals in sub-Saharan Africa. Between 2016 and 2021, 29 children received implanted bone conduction hearing devices, and 104 children were fitted with bone conduction devices on softbands...

BACKGROUND AND AIMS: Conserved specimens do not decay and therefore permit long-term experiments thereby overcoming limited access to fresh (frozen) temporal bones for studies on middle ear mechanics. We used a Thiel conservation method which is mainly based on a watery solution of salts. In contrast to pure Formalin, Thiel conservation aims to preserve the mechanical proprieties of human tissue. The aim of this study is to examine the effect of Thiel conservation on bone conduction in the same specimen before and after conservation...

OBJECTIVES: Unilateral aural atresia (UAA) is a congenital condition that is associated with maximal conductive hearing loss. The primary objective of this study was to assess the long-term compliance, complications, and quality of life of pediatric patients with UAA who had transcutaneous bone conduction hearing implants (TCBI). METHODS: Retrospective consecutive case series at a single centre between 2014 and 2018. Inclusion criteria consisted of UAA patients between 5 to 17 years-old receiving the Cochlear Baha Attract ® device...

PURPOSE: This study investigated whether the magnetic field of the internal magnet of cochlear implants and bone-anchored hearing aids (BAHA) would be sufficient to affect a programmable ventriculoperitoneal (VP) shunt. Current guidelines suggest against implanting these hearing devices ipsilateral to a programmable VP shunt, but the exact nature of the interaction has not been quantified. METHODS: The magnetic field strength (mT) was measured at 0 and 10 mm from the edge of both the Cochlear Implant CI512 (Cochlear Corporation) magnet and BAHA Attract magnet...

BACKGROUND: The cases of ear malformations, conductive, mixed, and single-sided deafness hearing loss are candidates for surgery and use of Bone-Anchored Hearing Aids (BAHA). Commonly, the literature highlights two procedures to assess the benefits and characteristics of amplification in users: functional gain (FG) and effective gain (EG). OBJECTIVE: Estimate and compare the EG and the FG to evaluate the benefits obtained by users of BAHA and, later, to compare tests of speech perception in silence and in noise...

INTRODUCTION: Bone-anchored hearing devices (BAHD) are well-known good solution for single-sided deafness (SSD). Despite power extension of recently introduced BAHD with implanted active transducer, with indications up to 65 dB Hl of bone conduction (BC) threshold on the implanted side, their indications for SSD still remain better than 25 dB on the good ear, with regards to bone conduction thresholds. The aim of this study was to assess the possibility to enlarge BAHD indications for SSD by means of a newly proposed candidacy evaluation protocol, which includes a new software-aided method...

PURPOSE: The aim of the study is to compare the operative time and postoperative complication outcomes for bone-anchored hearing aid (BAHA) implants using two different techniques: the C-shaped incision technique and the linear incision technique. METHODS: An analysis was carried out of 38 patients implanted with transcutaneous BAHAs during a 4-year period in a single otolaryngology department. RESULTS: The implantation was carried out under general anesthesia...

PURPOSE: To determine whether patients have improved quality of life outcomes with percutaneous bone conduction implant (p-BCI) versus transcutaneous bone conduction implant (t-BCI). MATERIALS & METHODS: Retrospective chart review of patients who have undergone placement of a BCI in the Ascension St John Providence Health System from 2013 to 2018. Patient satisfaction of t-BCI and p-BCI was measured using a questionnaire that incorporated the Glasgow Benefit Inventory (GBI) and BAHA, aesthetic, hygiene & use (BAHU) survey...

OBJECTIVE: Hearing loss is a growing public health issue that significantly impacts both health-related quality of life and working life. This study investigates how hearing rehabilitation with bone conduction hearing implants impacts health-related quality of life and working life in adults of working age with hearing impairment. DESIGN: This longitudinal study used data from Cochlear's Implant Recipient Observational Study to assess hearing disabilities and job satisfaction in 18-65-year-old recipients of bone conduction hearing implants...

Unfortunate loss or absence of an ear has a far-reaching impact on an individual psyche. Auricular defects are seen commonly due to trauma, congenital abnormalities, and malignancies which result in disfigurment of the pinna. Rehabilitation of an auricular defect with a custom-made auricular prosthesis improves social acceptance and self-confidence in an individual. Auricular defects present reconstructive challenges, especially if they are bilateral. Surgical reconstruction provides effective results for defects; however, for some patients, surgical intervention is contraindicated...

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...

OBJECTIVE: Transcutaneous bone anchored hearing devices (BAHDs) were introduced in an effort to avoid potential complications associated with the abutment of percutaneous BAHDs. Transcutaneous BAHDs can be active or passive. While studies have demonstrated good outcomes with both, a direct comparison of audiological and clinical outcomes of these devices in the pediatric population has not yet been studied. STUDY DESIGN: Retrospective, multicenter study. SETTING: Two tertiary academic centers...

Mucopolysaccharidosis VII (or Sly syndrome) is an autosomal recessive disorder characterised by a deficiency in the enzyme Beta-glucuronidase ( GUSB ). Partial degradation of glycosaminoglycans (GAGs); chondroitin sulfate (CS), dermatan sulfate (DS) and heparan sulfate (HS) results in the accumulation of these fragments in the lysosomes of many tissues, eventually leading to multisystem damage. In some cases, early diagnosis on clinical grounds alone can be difficult due to the extreme variability of the clinical presentation and disease progression...

About 70% of people with osteogenesis imperfecta (OI) experience hearing loss. There is no cure for OI, and therapies to ameliorate hearing loss rely on conventional treatments for auditory impairments in the general population. The success rate of these treatments in the OI population with poor collagenous tissues is still unclear. Here, we conduct a systematic review and meta-analysis on the efficacy of treatments addressing hearing loss in OI. This study conforms to the reporting standards of the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA)...
