1 Introduction Around 5% of the world's population, which is approximately 430 million people, are suffering with some degree of hearing loss requiring rehabilitation to restore it [1]. Hearing aid is a solution for mild to moderate hearing loss conditions, whereas cochlea implant (CI) is the solution for sensorineural hearing loss conditions [2]. A CI has two components, namely the externally worn sound processor and the implantable component.

Abstract The aim of this study was to understand the mastoid volume development in children who undergo cochlear implantation surgery. Cochlear implant (CI) database of our clinic (Kuopio University Hospital) was reviewed for computed tomography (CT) images of CI patients (age under 12 years at the time of implantation) with a minimum time interval of twelve months between their pre- and postoperative CT. Eight patients (nine ears) were found eligible for inclusion.
