Hearing Rehabilitation Experiences With Osia®2 Bone Conduction Hearing Implant in Patients With Iatrogenic Unilateral Hearing Loss

Abstract

Various types of bone conduction hearing aids have been widely used for hearing rehabilita-tion for the last 30 years. Among them, the recently launched Osia®2 system is a new activetranscutaneous bone conduction implant system using piezoelectric effect. This can be ex-pected to deliver more efficient sound transmission, overcome sound attenuation, and improvehigh-frequency hearing than conventional passive transcutaneous hearing aids, and is consid-ered to be cosmetically superior to percutaneous hearing aids. Recently, we experienced twocases of Osia®2 implantation in patients with iatrogenic unilateral hearing loss. Both patientsshowed improved pure tone threshold and better Korean Hearing in Noise Test (K-HINT) scoreafter implantation. Furthermore, all of them had no complications after Osia®2 implantation.
