Pulsating in ear, also known to be pulsatile or vascular tinnitus, is a type of tinnitus which can be heard on your ears. What happens is that the patient experiences sensation in the ear as the same tempo as that of a heartbeat. This common type of sensation is caused by the blood flowing in veins and arteries and other smaller vessels in the neck, skull and ear. Even if this is uncommon condition, it still needs immediate medical attention as it may be an expression of a life threatening ailment.
Causes of a pulsating in ear could be caused by so many factors. Some of these factors are chronic inflammation or middle ear infection, Eustachian tube dysfunction, middle ear effusion vascular tumors, arteriovenous malformations, carotid artery cavernous sinus fistula and venous hum. Due to the nearness of the location in the chronic inflammation, sensitiveness to the increased blood flow perception may be noticed, since this is most often accompanied by an increased blood flow to the inflamed tissue. In the case of a Eustachian tube dysfunction, its tube is blocked due to a sinusitis, colds, cough, allergies or excessive earwax, thus resulting to a pulsating in ear.
This symptom may also occur in the middle ear if there is an infection, inflammation or Eustachian tube dysfunction. The pulsating in ear would be a result from the fluid that increases in the middle ear. This sometime causes pain. Patient will be relieved with antibiotics, decongestant and nasal steroid sprays. Another pulsating sign is a vascular tumor referred to as gloms tumors or paragliomas. Though not dangerous, but it could get annoying as it is an area that is sensitive to hearing. To address the problem of the ear, it has to be removed through an invasive surgery.
Another cause of pulsating in ear could come from arteriovenous malformations. These are abnormal group’s arteries and veins that transform in the cranial cavity near the auditory nerve and this could pulsate in auditory nerve. Surgery is the best approach for this condition to regain the function of the damaged or injured areas. In carotid artery-cavernous sinus fistula originating from a head trauma, there becomes abnormality in the connection between a very large artery and very large venous within the cranial cavity, and could also create various kinds of pulsating in ear. It may be treated nonsurgical, but it should be taken cared of and consistently check by an interventional radiologist.
A reason of having pulsating in ear would be the sudden change in blood flow in arteries and veins. Those who are affected usually are the pregnant, anemic, or those with thyroid problems. What happens is that there is an increased blood flow in the largest vein located in the neck. This jugular vein transmits blood from the brain going back to the heart, and since it passes to the middle ear know found inside the ear.
