Hearing loss is the most common sensory impairment. More than 5 % of the world's population suffers from disabling hearing loss, which affects approximately one third of people over the age of 65. In those cases where hearing aids are not a sufficient solution to these difficulties, cochlear implantation is the standard treatment. It replaces, at least in part, the function of the hair cells that are no longer able to stimulate the primary auditory neurons. However, there are concerns about the potential risk of impaired vestibular function and the development or worsening of non-vestibular problems such as tinnitus, vertigo and orofacial disorders. Aims: To provide a theoretical summary of fundamental information on the vestibular system and cochlear implantation and to assess vestibular and non-vestibular function after cochlear implantation and the impact of any abnormalities on patients' quality of life. Methods: All of the participants underwent subjective visual vertical examination, platform posturography and completed five questionnaires - Dizziness Handicap Inventory, Tinnitus Handicap Inventory, Facial Disability Index, Beck's Anxiety Inventory and Beck's Depression Inventory. Overall and partial results from platform posturography examinations were compared with a control group of...
