[Vestibular function in cochlear implant candidates].
BACKGROUND
The main problem of a deaf patient is per se communication process. Some of the patients, who are candidates to cochlear implantation report vertigo or imbalance in some everyday situations. The relation of patients' complaints to vestibular loss was evaluated. The authors used electronystagmography which was realized in diagnostic process to cochlear implantation. The results come from the patients diagnosed in our department in 2006-2007. In accordance to the literature, the true vertigo, was rather rare.


METHODS
Medical history, caloric tests as electronystagmography results were evaluated retrospectively in 47 patients qualified for cochlear implantation in 2006-2007.


RESULTS
In the study group, 25 patients did not complain of vertigo; with symmetrical calorics in 10 subjects (40%). The true vertigo reported 6 subjects; 8 subjects had imbalance and unsteadiness on walking. In the group of 47 subjects 8 of them complainted the both- vertigo and imbalance. In the ENG of this group the results of symmetrical responces were evaluated in 57% cases and vestibular hypofunction in 43% subjects. In the group with vertigo (6), 4 subjects (66%) had diagnosed unilateral hypofunction, 1 (17%) bilateral areflexion, 1 subject (17%) had symmetrical responses.


CONCLUSIONS
The necessity of the confrontation ENG results to additional examination in audiological part of diagnostic process to cochlear implantation is underlined.
