Abstract
It is a well-known fact that inner ear diseases are often caused by microcirculatory disorders, and the recent literature is oriented towards investigations into the relationship between the cardiovascular system and cochleovestibular illness with related classical symptoms: tinnitus, hearing loss, and vertigo or instability. These symptoms, and particularly the vertigo, may be the alarm signal of microcirculatory disorders of the labyrinth or vertebrobasilar circulation so as to represent a possible symptom of posterior circulation stroke. The treatment aimed at correcting the haemodynamic and metabolic imbalance, generated by the cochleovestibular microcirculatory disorders, with drugs that act on the vessel wall being very useful, both alone and in combination with other treatment protocols. This is a multicenter retrospective observational study conducted in 40 neurootological laboratories with 873 patients with cardiovascular risk factors suffering from tinnitus, instability or peripheral vertigo alone or in combination with one another treated for the first time with mesoglycan. The data collected showed that the treatment with mesoglycan, irrespective of the type of vascular risk factor, is not only well tolerated but also significantly and objectively improves the cochleovestibular symptoms and the quality of life of patients suffering from tinnitus, peripheral vertigo and instability.
