Tinnitus is actually not disease. It is just a symptom of some other disorder in your system. Tinnitus is often described as ringing sound in one or both of your ears. However, it can occur in other forms of sound as well, such as buzzing, whooshing, or hissing. Whatever type of sound tinnitus sufferer hear, there is no external source for that noise. The noise is produced within his or her body and usually the sufferer is the only person who can hear it.
It is very common that tinnitus is caused by some inner ear disorder. Some common causes of that disorder include exposure to loud noises, head injuries, and ear infections. Sometimes the causes of tinnitus can be a little bit more serious as well.
Pulsatile tinnitus is often called as vascular tinnitus. Usually, this type of tinnitus appears in just one ear. It has been reported that only one out of twenty tinnitus patients has vascular tinnitus.
Vascular tinnitus, unlike other varieties, is not often inner-ear specific. A Eustachian tube blockage, or ear infection, can be the culprit, as with other varieties of tinnitus.
Vascular tinnitus is usually caused by increased blood circulation near the patients ear. The flow is so extreme that the sufferer can hear the blood passing his or her ear.
Tumultuous blood flow can occur during the relatively benign event of arduous exercise. It can be caused by anemia, particularly in pregnancy. It can occur with hyperthyroidism.
Nevertheless, often the cause of this type of tinnitus is the contraction of blood vessels causing constriction in blood flow. In those cases, the pulsating and whooshing noise the patient hear is due to variation in blood flow.
Physical conditions or diseases that may lead to blood vessel constriction, in turn leading to pulsatile tinnitus, include hypertension and arteriosclerosis. These two often go hand in hand, lethally causing constriction of the arterial walls. Other conditions include heart murmurs and certain kinds of tumors.
While there is some varying degree of risk associated with the tinnitus causes related to vascular tinnitus, there is the very real risk of stroke associated with constriction in the cranial or neck vessels extreme enough to lead to the characteristic auditory symptoms of vascular tinnitus. For this reason medical advice and subsequent testing is always advisable for subjects experiencing tinnitus with the qualities inherent to pulsatile tinnitus.
