Bone anchored hearing aids in children: An update

ObjectiveOver recent years, there have been a significant number of publications reporting evolving bone anchored hearing device (BAHD) indications and modifications in surgical techniques. We aim to present a review of recent trends in paediatric BAHD surgery and also discuss alternative treatment options available.MethodsAll papers referring to paediatric BAHD surgery (English language) were identified from Medline, Pubmed, Cochrane library and Embase search in May 2011. Abstracts were read and relevant papers were obtained.ResultsBAHDs have evolved over recent years as technology has advanced. New bone conduction hearing devices have recently been launched such as the Ponto system [Oticon™], Alpha 1 (M) hearing system [Sophono™], Soundbite system [Sonitus™] and the Vibrant Soundbridge system [Medel™]. Modifications to existing implant systems have significantly altered BAHD practice with earlier loading of the sound processor now a positive step forward.ConclusionsThe latest generation of percutanous devices have been designed to reduce skin complications, promote better osseointegration and earlier loading of the sound processor. Alternative devices without a skin-penetrating abutment are now available and have shown promising results in the paediatric population.
