Aim. Ver­tigo and bal­ance dis­tur­bances are not fre­quently ­observed in tin­nitus ­patients, so ves­tib­ular func­tion is not ­often ­under ­study. We ­decided to eval­uate the ves­tib­ular ­system in tin­nitus ­patients ­without the pres­ence of ver­tigo or diz­zi­ness.
­Methods. Clin­ical exam­ina­tion, audio­logic and elec­tro­nys­tag­mog­raphy ­tests in 50 tin­nitus ­patients diag­nosed in the ENT Depart­ment of the Med­ical Uni­ver­sity of ­Lodz and 30 ­healthy per­sons ­were car­ried out. The bal­ance ­system was eval­u­ated by 4-­channel ENG ­system. ENG ­tests ­like spon­ta­neous and posi­tional nys­tagmus, ­caloric and ­kinetic ­tests, ­smooth pur­suit and opto­ki­netic ­tests ­with ­velocity 28º/s and 38º/s, and sac­cadic ­tests ­were per­formed. We ­applied age appro­priate, our labor­a­tory nor­ma­tive ­data for all ­tests. We com­pared ­each ENG ­test ­results ­of the tinnitus group with the con­trol ­group and all tin­nitus ­patients ­tests ­results ­with the ­group of 32 ­patients (64%) who ­were ­without any ver­tigo inci­dent.
­Results. ­Abnormal ENG out­come in tin­nitus ­patients in ­caloric, ­kinetic ­tests and ­ocular-­motor ­tests ­were sig­nif­i­cantly ­more ­often ­recorded ­than in the con­trol ­group. In 17 sub­jects (34%) tin­nitus ­group abnor­mal­ities ­were ­found in 2 ENG ­tests and in 10 per­sons (20%) in 3 ­tests. In the con­trol ­group incor­rect record­ings ­were ­observed ­only in ­single ­tests. ­Signs of cen­tral ves­tib­ular ­system impair­ment ­were ­observed in 23 tin­nitus ­patients (46%), periph­eral in 2 ­patients (4%) and ­mixed in 6 ­patients (12%). ENG exam­ina­tion was in the ­normal ­range in 19 ­patients (38%). No sta­tis­tical dif­fer­ences ­were ­found ­between the num­bers of ­abnormal ENG ­tests ­results ­between all tin­nitus ­patients and ­these who had pre­vious ver­tigo.
Con­clu­sion. In tin­nitus ­patients ­abnormal record­ings sug­gesting cen­tral ves­tib­ular dis­order in ENG ­tests ­were fre­quently ­observed and dis­tri­bu­tion of ENG record­ings was sim­ilar in per­sons ­with or ­without pre­vious ver­tigo.
