Pulsatile Tinnitus

by Barry Keate

Pulsatile tinnitus is the type of ear noise that is perceived as a rhythmic pulsing that is often in time with the heartbeat. It can be experienced as a thumping or whooshing sound. It is sometimes referred to as vascular tinnitus because in the majority of cases, it is related to disturbances in the blood flow. About 3% of tinnitus patients experience this type of tinnitus.

Pulsatile tinnitus usually originates within the blood vessels inside the head or neck region when disturbed blood flow occurs. This results from either increased blood flow or a narrowing of the opening of the blood vessel, both of which result in turbulent blood flow that can be heard in the ears. In this regard, it is totally different from and independent of continuous tinnitus which results from damage to the cochlea and/or hearing nerve.

It is very possible to have both pulsatile and continuous tinnitus together. People who have both of these generally say the pulsatile component is the more bothersome.

It is important to investigate all instances of pulsatile tinnitus. In some cases, a serious underlying condition could exist. In rare cases, this can lead to a catastrophic event such as stroke. A series of tests, beginning with an examination of the head and neck by a physician familiar with the condition, through complex imaging techniques, is performed. Individuals who find that the initial imaging results do not reveal abnormalities should insist on further examination and investigation. It is possible to misread or miss these trouble spots that may be tangled in other structures or hidden by bone or other tissue. Newer imaging techniques, such as Magnetic Resonance Angiography and Carotid Artery Ultrasonography, have been employed that help determine the site of the problem in the majority of pulsatile tinnitus cases. The cure rates for pulsatile tinnitus are quite high once the problem area has been identified.

The following section describes some of the more common causes of pulsatile tinnitus and relevant therapies.

1 – Benign Intracranial Hypertension (BIH). This is a condition where there is increased pressure of the cerebrospinal fluid that bathes the brain. The majority of these patients are young females who are generally overweight. Other symptoms of BIH may include hearing loss, ear fullness, dizziness, headaches and visual disturbances. Management of this condition includes weight loss and administration of a diuretic. Most patients improve dramatically with weight reduction alone.

2 – Glomus Tumor. This is a benign vascular tumor usually located in the ear or just below the ear at the skull base. It consists of a mass of intertwined blood vessels. Hearing loss is also a common symptom. Young patients are usually treated surgically, to remove the tumor, while older patients may need no treatment since they are very slow growing.

3 – Atherosclerotic Carotid Artery Disease. Atherosclerosis is the narrowing of the artery due to cholesterol build-up on the artery wall. This reduces the opening resulting in turbulent blood flow that produces pulsatile tinnitus. This usually occurs in older patients with a history of hypertension, elevated cholesterol, diabetes, angina and smoking. The condition can usually be controlled through medication.

4 – Intracranial Vascular Lesions. These include aneurism and arteriovenous malformation, which is an abnormal connection between an artery and a vein.The blood flows directly from a high pressure artery to a lower pressure vein without going through the capillaries. Either aneurism or arteriovenous malformation can lead to bleeding in the brain and can be extremely dangerous. Therapies include surgery and embolizing (closing off) the blood vessels.

5 – Middle Ear Effusion. The middle ear is normally an air-filled space. If fluid accumulates in the middle ear due to infection, inflammation or Eustachian tube dysfunction, pulsatile tinnitus can result. It is sometime accompanied by decreased hearing, a feeling of fullness, and may also include pain. This is most often treated with antibiotics, decongestants, nasal sprays, etc. or sometimes surgery.


6 – Venous Hum. Patients who are pregnant, anemic, or have thyroid problems, may develop increased blood flow through the jugular vein, the largest vein in the neck. The jugular vein traverses the middle ear and any turbulent flow in the vein can be heard in the middle ear as a “hum” which may or may not fluctuate with the pulse. Correction of the underlying problem generally results in improvement or resolution.

7 – Hypertension. There are reports of patients with high blood pressure whose pulsatile tinnitus started after they began taking blood pressure medication. Tinnitus subsided in most after four to six weeks. For the remainder, a change to another medication resolved the issue. Others developed tinnitus from elevated blood pressure and it resolved after medication reduced the pressure.

8 – Twisted Arteries. Twisted arteries in the head and neck cause turbulent blood flow leading to pulsatile tinnitus. It generally does not require treatment.

These are the primary causes of pulsatile tinnitus but not an exhaustive listing.

9 – Other Causes. Other causes can include Arnold-Chiari malformation where an elongation of the cerebellum is pushed down through the opening of the base of the skull, blocking the flow of cerebrospinal fluid. Muscle spasm in the soft palate can cause a clicking sound which is rapid (60-200 beats per minute), repetitive and intermittent. This is associated with multiple sclerosis, small vessel disease, tumor or degenerative neurological disorders. The small muscle attached to the stapes bone in the middle ear can spasm which produces a crackling or rumbling noise. There are other, mostly rare, causes of pulsatile tinnitus as well as those mentioned here.

If pulsatile tinnitus is caused by turbulent flow in arteries, pressure applied to the upper neck on the side of the tinnitus should alter or reduce it. If it is venous in origin, the Valsalva maneuver may improve it. This is performed by forcibly exhaling against closed lips and pinched nose, forcing air into the middle ear, provided the Eustachian tube is open. Neither of these is a fool-proof way of identifying or alleviating the problem but positive results may lead to a better diagnosis by a physician.

Arches Tinnitus Relief Formula® is helpful in many cases of pulsatile tinnitus. The mechanism of action is Ginkgo biloba extract reduces the viscosity of the blood and arterial pressure which in turn reduces the throbbing or pulsing effect. People with pulsatile tinnitus should always undergo a thorough evaluation to ensure that serious consequences, such as stroke, will be prevented.

Hi, before you get too worried you could just be having simple palpitations, these odd skipped beats or double ones happen to perfectly healthy people too. Meds can cause them as well as stress. Oh, and yes, I sometimes get a weird beat too, but then I notice everything my heart does nowadays! Do you think you're just being over-aware now, because of the ear plugs and your heart issues? Sometimes we concentrate so hard we become aware of things we never even noticed before and then we worry.
It's good you're going to get it checked out, peace of mind is what you need, I'm pretty sure you've got nothing to worry about!

I often get tinninitus, especially when I am in a prone position, which is quite often these days. It is certainly irritating and I notice that the more I focus on it the louder it becomes. I think the ear plugs also have something to do with it.

Good luck in figuring this one out.

Deadr HI77,

Gracie adds some wise advice. Please remember while reviewing the medical litertature that the most extreme scenerio is generally presented. We all fall somewhere on a continuum and we are all different.

I'm glad, however, that you are being checked out. This symptom would also panic me if I had it .

Hope to hear from you again because now you have my curiosity hopping.

Have a Beautiful Day!

Sherrie

hi77,
It's a good idea to get that checked out, but Grace has a good point. It is very easy to become hyper-aware of your heartbeat and think you are feeling/hearing irregularities. I did the same thing, I would lie in bed and listen to my heartbeat and try to detect any irregular beat. I have had a couple of 24-hour holter moniters, both normal. It took a few months to relax enough to not notice my heartbeat anymore. If you are having palpitations, often times they are harmless if your heart is otherwise healthy. I have them in times of stress (mental or physical) and it sounds a lot like what you are describing. It is always good to get checked out, that's a good decision. If it's nothing, try not to let it take control of you. Good luck!

thank you everyone, i do have to take the earplugs out lately, because i can't stop paying attention and listening for weird things

please tell me- what is a palpitation? just want to make sure, because it just felt like the heart stopped in the middle of a beat and then started up again- is this what that's called?

Hi, that's exactly what it is, a skipped beat or a slower beat, just a little change of rhythm. I know it's hard to ignore once you become aware of your heart beat, it's a bit like picking a spot, you just can't leave it alone, even though you know you should. Have you had a word with your Doctor yet? It might help if you tell him/her just how it feels and you can get some reassurance.

Good idea to take the earplugs out by the way!
