Abstract
  • Purpose: The purpose of this systematic review is aimed to examine the current literature and findings to determine if use of intervention with a bone-anchored hearing aid (BAHA) in children with unilateral hearing loss leads to improved localization and speech in noise test results over no intervention. Background: Many studies have demonstrated that children with unilateral hearing loss may struggle both academically as well as behaviorally. These studies have also found that people with UHL demonstrate greater difficulty in noisy situations than normal hearing peers. There remains limited data on the efficacy of different treatment options for unilateral hearing loss (UHL) in children, however. One such option is a surgically placed BAHA. This is typically only recommended in cases of profound unilateral hearing loss and is currently only approved for use in adults and in children ages 5 and older. Methods: We conducted a systematic review using the search strategy (BAHA OR bone anchored hearing aid) AND (localization OR “speech in noise”) AND child* AND (UHL or unilateral hearing loss) on two databases, Pubmed and CINAHL, while using Google Scholar as a supplementary database. We restricted our publication dates of articles used from anytime-March 2017. Our exclusion criteria included case studies, expert opinion articles, participants over 18, non-English studies, cochlear implants or hearing aids, and bilateral hearing loss. Anticipated Results: We expect to find little research in this area, but also expect to find some positive findings that a BAHA will be beneficial for children with UHL in speech in noise and localization tests. Discussion: While there was some evidence of benefit and no evidence of detriment in the use of a BAHA to treat children with UHL, the lack of high quality research indicates that larger and more in depth studies are needed.
