Pulsatile tinnitus: Coping with ear ringing similar to heartbeat in earUnlike 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.

What causes pulsatile tinnitus?

What causes 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:

  • Head and neck tumors
  • Atherosclerosis
  • High blood pressure
  • Turbulent blood flow
  • Malformation of capillaries
  • Altered awareness: conductive awareness occurs when a perforated eardrum causes the individual to become more aware of blood flow. Heightened sensitivity in the auditory pathways alerts the brain to normal noise in the blood vessels.

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:

  • Generalized increased blood flow: blood flow moves more quickly to the ear. This can occur due to exercise, pregnancy, hyperthyroidism or severe anemia.
  • Localized increased flow: a single blood vessel can increase blood flow to the ear.
  • Turbulent blood flow: the inside of a blood vessel becomes irregular causing blood flow to become turbulent.

Other causes of tinnitus

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:

  • Meniere’s disease
  • TMJ disorders – lock jaw
  • Head or neck injuries
  • Acoustic neuroma – a benign tumor
  • Certain medications (antibiotics, cancer drugs, diuretics, medications used for malaria, certain antidepressants can worsen tinnitus, aspirin)

Symptoms associated with tinnitus

There are two different types of tinnitus: subjective and objective. Subjective tinnitus is when the individual is hearing sounds that nobody else can. Objective tinnitus can be heard by the doctor during an examination and is much more rare than subjective.

Symptoms of tinnitus include:

  • Ringing
  • Buzzing
  • Roaring
  • Humming
  • Clicking
  • Hissing

Complications and risk factors of tinnitus

Complications and risk factors of tinnitusThere 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:

  • Loud noise exposure
  • Age
  • Gender (men are more likely to experience tinnitus than women, often because typical male jobs expose them to louder noises)
  • Smoking
  • Cardiovascular problems (they can affect blood flow)

Complications associated with tinnitus are:

  • Fatigue
  • Stress
  • Sleep problems
  • Trouble concentrating
  • Memory problems
  • Depression
  • Anxiety and irritability

Patulous Eustachian tube dysfunction and tinnitus

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.

Treating tinnitus

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:

  • Anti-anxiety or antidepressant medications
  • Using a fan or radio while sleeping as “white noise” in order to overpower nighttime tinnitus
  • Managing stress, which may worsen tinnitus
  • Tinnitus retraining therapy (TRT) to learn to accept sounds and become less aware of them
  • Avoiding the use of aspirin
  • Protecting the ears, so hearing loss does not worsen, i.e., avoiding loud noises
  • If caused by a tumor, involves treating or removing the tumor, if other medical conditions are the cause of tinnitus treatment of the underlying cause often helps the tinnitus
  • Cochlear implants
  • Earwax removal
  • Changing medications which may make tinnitus worse
  • Reducing alcohol consumption

Preventing tinnitus

Preventing tinnitusThere 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.
