Although there are studies evaluating hearing in psoriasis patients, its effect on the balance system is not clear. The aim of the present study was to evaluate the audiovestibular system in psoriasis patients without joint involvement. In this prospective study, the audiovestibular system of 32 psoriasis patients without joint involvement and 35 healthy volunteers were evaluated. The severity of the disease was determined by the psoriasis area severity index (PASI). There was no significant difference between the groups in terms of hearing test results, while the abnormal caloric test response was significantly higher in the psoriatic patients. PASI scores of psoriasis patients with abnormal caloric test results were higher than those with normal caloric test response. In psoriasis patients without joint involvement, the hearing was not affected, but the vestibular system was. The severity of the disease was associated with vestibular involvement. Particularly in patients with severe psoriasis, it must be considered that the vestibular system might be affected, and vestibular evaluations should be performed.
