Simultaneous bilateral transcutaneous bone conduction device implantation: sound localisation and speech perception in children with bilateral conductive hearing loss

This study investigated the audiometric and sound localisation results in patients with conductive hearing loss after bilateral Bonebridge implantation. Eight patients with congenital microtia and atresia supplied with bilateral Bonebridge devices were enrolled in this study. Hearing tests and sound...

Description
Summary:This study investigated the audiometric and sound localisation results in patients with conductive hearing loss after bilateral Bonebridge implantation. Eight patients with congenital microtia and atresia supplied with bilateral Bonebridge devices were enrolled in this study. Hearing tests and sound localisation were tested under unaided, unilateral and bilateral aided conditions. Mean functional gain was higher with a bilateral fitting than with a unilateral fitting, especially at 1.0-4.0 kHz (p < 0.05, both). The improvement in speech reception threshold in noise with a bilateral fitting was a 2.3 dB higher signal-to-noise ratio compared with unilateral fitting (p < 0.05). Bilateral fitting had better sound localisation than unilateral fitting (p
