Introduction
The ear is an important sensory organ that contains nerves for balance as well as hearing. It is divided into a so-called middle ear and an inner ear. Since the structures in the ear are very small, the arteries that supply the cells of the ear with oxygen are also small.
Circulatory disorders are often noticed very early on in the ear, as even small failures can sometimes have a major impact. For example, circulatory disorders can lead to the loss of the entire sense of hearing, which is also known as sudden deafness. In some cases, the clinical picture of tinnitus aurium can also be attributed to circulatory disorders in the inner ear. Circulatory disturbances in the region can sometimes manifest themselves as symptoms of dizziness, since the organ of equilibrium is anatomically very closely connected to the inner ear.
Cause
The causes of circulatory disorders in the ear are similar for the whole organism. The difference is that the vessels that supply the ear are much smaller than most other vessels in the body. Circulatory disorders can in many cases be attributed to blocked arteries.
This disease, called arteriosclerosis, can massively disrupt the blood flow in the inner ear. Blood lipids, coagulated blood and calcium are deposited in the arteries and can even block them. If the arteries leading to the inner ear are completely or incompletely blocked, the structures of the ear are undersupplied and hearing disorders such as sudden deafness occur.
Factors of risk, which favor the emergence of a Arteriosklerose are among other things illnesses like Beside a Arteriosklerose also injuries can release a blood circulation disturbance of the ear. Especially when the cervical spine or the skull is injured, the blood circulation of the ear is potentially at risk. At an advanced age, degenerative changes in the cervical spine should also be considered if the cause of the circulatory disorders is not obvious.
Sometimes tumors can also be the cause of the circulatory disorder. For example, a growing tumor can push off an artery that normally supplies the inner ear with nutrients and oxygen.
- High blood pressure,
- Diabetes mellitus,
- A high proportion of blood lipids,
- Smoking
