Tinnitus is a sensation of ringing in the ears in the absence of any physical source in the environment. Between 9-35% of adults experience some form of tinnitus. Common causes of tinnitus include noise, head injury, ototoxic substances, as well as disorders of blood and blood vessels. Vascular causes include: head-neck tumours, turbulent blood flow, problems with blood supply and inner ear cell damage. The aspect of rheology in terms of tinnitus has not been described yet. In the present study, which comprised 12 patients aged 30 to 74 years presenting with tinnitus, rheological properties of whole blood and plasma were assessed. All the subjects underwent audiological and neurological evaluation. The Quemada model was used to describe the variability of red blood cell shape, as well as their tendency to form aggregates. On the basis of the experimental study, statistically different results of haemorheological measurements were observed in the evaluated group in comparison to a reference group.
耳鸣是指在环境中没有任何物理声源的情况下耳朵发出的响声。9-35%的成年人会经历某种形式的耳鸣。耳鸣的常见原因包括噪音、头部损伤、耳毒性物质以及血液和血管疾病。血管性原因包括：头颈部肿瘤、血流紊乱、血液供应问题和内耳细胞损伤。耳鸣在流变学方面的方面尚未被描述。在本研究中，纳入了 12 名年龄在 30 至 74 岁之间的耳鸣患者，评估了全血和血浆的流变学特性。所有患者均接受了听力学和神经学评估。使用 Quemada 模型来描述红细胞形状的可变性以及它们形成聚集的趋势。基于实验研究，在评估组中观察到与参考组相比，血液流变学测量的统计学差异结果。
