Unlike regular tinnitus, which is ear ringing, pulsatile tinnitus can feel like a heartbeat in the ear. Pulsatile tinnitus is a rhythmic noise in the heart, which sounds similar to a heartbeat. If you were to check your heartbeat while experiencing pulsatile tinnitus, you would uncover that both rhythms are the same. This is what makes pulsatile tinnitus different from regular tinnitus; in tinnitus the sounds involve ringing, buzzing or rushing and tend to be steady and frequent without stopping.
It is often difficult for doctors to find the exact cause of tinnitus; however, they commonly uncover a cause for pulsatile tinnitus.
Common tinnitus is usually caused by cell damage within the ear. This cellular damage can result from age, loud noises, earwax blockage and even changes in the ear bone. Pulsatile tinnitus, on the other hand, is commonly caused by blood vessel disorders. The following can cause blood vessel disorders:
Essentially, in pulsatile tinnitus, the main cause is a change in the blood flow in the ear. Causes for these changes in blood flow include:
As mentioned, tinnitus can be caused by cell damage in the ear, resulting from age, loud noises, earwax blockage and changes to the ear bone. Other causes of tinnitus include:
Symptoms related to pulsatile tinnitus include hearing a steady sound which syncs with your heartbeat. This sound may only be heard in one ear. This sound can be distracting and for some completely unbearable and make performing daily tasks difficult.
Other symptoms may arise in pulsatile tinnitus if a patient has high pressure of fluid around the brain. This is known as idiopathic intracranial hypertension and the symptoms include:
There are many factors that can contribute to not only tinnitus, but hearing loss as well. Some of them are unchangeable, but many of them are lifestyle factors, which you can control to improve your odds of not developing tinnitus. Risk factors of tinnitus include:
Complications associated with tinnitus are:
Patulous Eustachian tube (PET) dysfunction is a condition where the Eustachian tube does not open properly due to the swelling of the tube’s tissues or surrounding areas, such as the tonsils or adenoids. The Eustachian tube runs from the pharynx to the cavity of the middle ear, allowing pressure to be equalized in the eardrum. Patulous Eustachian tube dysfunction can lead to symptoms such as hearing one’s own voice abnormally loud, hearing generally sounds abnormally loud and sometimes distortion of speech and sounds overall.
Treatment for Patulous Eustachian tube dysfunction involves surgery to correct or modify the Eustachian tube or to partially plug the tube.
Pulsatile tinnitus diagnosis begins with your doctor taking your medical history and symptoms. They will also examine your eardrums and blood vessels in the neck. Another important diagnostic measure for pulsatile tinnitus is the use of images. There are a variety of imaging techniques including ultrasound, MRI, MRA, CT scan, CTA, and angiography.
Your doctor may also request blood tests to rule out other causes of ringing in the ears. Blood tests can rule out anemia. Your doctor may also request a thyroid function test if they suspect an overactive thyroid is the root cause.
You may have to see a series of doctors to obtain a proper diagnosis including an ophthalmologist or neurologist which may request their own set of specialized tests.
There are numerous treatments available for tinnitus to lessen the ringing and buzzing one may have to endure, unfortunately, there is no cure for tinnitus. Treatment of tinnitus can include any of the following:
There are many different causes of tinnitus, some of which simply cannot be prevented. However, some of the causes can be prevented through awareness and lifestyle changes. For example, you will want to protect your ears from prolonged loud noises, just as you would if you were preventing hearing loss. Wearing earplugs and minimizing or avoiding areas of loud noises can help protect your ears.
Additionally, keep volumes to a minimal – especially if you are wearing headphones. TV volume should also be kept in normal range. Lastly, proper cardiovascular health is another way to prevent tinnitus, including pulsatile tinnitus. Lifestyle factors, such as not smoking, eating well and exercising, can go a long way to improve heart health.
Although you can turn back time or reverse damage that has already occurred, by becoming more mindful to ear threats you can slow down any future hearing problems, and help prevent the complications which come along with hearing loss and tinnitus.
