title: [Tinnitus in systemic diseases].
abstract: Permanent or temporary degenerative changes in the internal ear causing tinnitus may occur with particular intensity in patients suffering from systemic disease (diabetes, hypertension, rheumatic diseases, kidney and thyroid gland diseases). Pathomechanisms of hearing impairment and the risk of tinnitus and its character in particular cases are discussed in the paper. The research was carried out on 1200 patients treated in the Laryngological Rehabilitation Centre in Poznań between 1.1.1998 and 04.2001 due to tinnitus. The analysis included the diagnosis of general health condition, general laryngological examination as well as additional tests. In the examined group 34% suffered from systemic diseases. Among them the highest percentage (47%) suffered from hypertension, 41% from hypercholesterolaemia, 22% from rheumatic diseases and 16% from diabetes. 96% of the patients had a long family history of diseases. The additional factor causing damage of the internal ear may be ototoxic drug used in the treatment of many systemic diseases.
