central nervous system with information about head spatial orientation and movement. The pioneering work of Bernard Cohen and Jun-Ichi Suzuki in the 1960s, who rst described eye movements originating from electrically stimulating the ampullary nerves of rabbits, pigeons, cats, and monkeys [1], inspired Gong and Merfeld, who described the rst vestibular prosthesis that was tested in guinea pigs [2]. Those animal experiments paved the way for human research. In 2004, the rst human patients under­went vestibular stimulation before undergoing surgery for cochlear implantation or sur­gical labyrinthectomy [3]. In these trials, it was conrmed that electrical stimulation of the ampullary nerves could produce a nystagmic response aligned with the plane of the stimulated canal. After this proof of concept, Guyot etal. performed the rst vestibular implantation in humans in 2007 [4]. This implant was a modied CI (MED-EL, Innsbruck, Austria), in which one electrode was removed from the cochlear array and implanted in the vicinity of the posterior ampullary nerve. It was demonstrated that a patient could adapt to electrical stimulation of the vestibular system without too much discomfort and that, once the adaptation was completed, the electrical stimulation could be modulated to articially evoke smooth eye movements [5]. As these prerequisites for developing a VI were fullled, the implant was modied into a multichannel prosthesis and implanted for the rst time in 2012 by the Geneva-Maastricht Group [6]. At the moment, two main types of VIs exist: the semicircular canal implants and the otolith implants. There are two subtypes of semicircular canal (SCC) implants: pure VIs and cochleovestibular implants, which combine a CI with a VI.
