OBJECTIVE: To determine how best to modify osseointegrated (OI) devices or environmental settings to maximize hearing performance. STUDY DESIGN: Prospective cohort study. SETTING: Tertiary referral center. PATIENTS: Fourteen adults with single-sided deafness (SSD) with a minimum of 6 months OI usage and nine bilaterally normal hearing controls INTERVENTIONS: : Speech in noise (SIN) and localization ability were assessed in a multi-speaker array (R-Space) with patients repeating sentences embedded in competing noise and verbally indicating the source speaker, respectively...

The aim of this study was to compare audiological test results obtained from a sound processor (SP) attached to a Softband with those obtained from direct (abutment connection) bone conduction implant systems and magnetic passive bone conduction implant systems with different magnet strengths on patients implanted at our clinic. Twenty-four patients who were implanted with either an abutment or magnetic bone conduction implant system between January 2012 and December 2014 were analyzed for hearing results, such as free-field hearing thresholds, direct bone conduction hearing thresholds, and speech discrimination scores with aided and unaided conditions Both magnetic and direct osseointegrated bone conduction implant systems, as well as the Softband system, provide good hearing outcomes when compared with unaided performance; however, the abutment connection system gives better hearing thresholds in the higher frequencies...

An osseointegrated implant (e.g. bone-anchored hearing aid, BAHA) is a surgically implantable device for unilateral sensorineural and unilateral or bilateral conductive hearing loss in patients who otherwise cannot use or do not prefer a conventional air conduction hearing aid (ACHA). The specific indications for an osseointegrated implant are evolving and dependent upon the country or regulatory body overseeing the provision of these devices. However, there are general groups of patients who would be likely to benefit, one such group being patients with congenital aural atresia...

Search Tips

Use Boolean operators: AND/OR

diabetic AND foot
diabetes OR diabetic

Exclude a word using the 'minus' sign

Virchow -triad

Use Parentheses

water AND (cup OR glass)

Add an asterisk (*) at end of a word to include word stems

Neuro* will search for Neurology, Neuroscientist, Neurological, and so on

Use quotes to search for an exact phrase
