What Causes Pulsatile Tinnitus or Pulsating Tinnitus

If you can hear a very distinct rhythmic pulse in your ears that synchronizes with your heart beat, there is a big possibility that you are suffering from a certain type of tinnitus called Pulsatile Tinnitus aka Pulsating Tinnitus.

Pulsatile Tinnitus Causes

According to Otolaryngologists or ENT, Pulsatile Tinnitus is commonly caused by irregularities of blood flow in a person’s arteries located in the neck or head, abnormalities in brain structure and sometimes it is caused by brain tumor.

In a study conducted by Dr. Robert Levine-clinician, researcher and director of Tinnitus Clinic at Massachusetts Eye and Ear Infirmatory in Boston, Pulsatile Tinnitus cause to some people is untraceable and they find no abnormalities even if they go through an extensive examination.

Dr. Levine explained that the probable cause of Pulsatile Tinnitus to these people is possibly associated with:

1. A sound generated by blood vessels near the inner ear beyond the doctors diagnostic capabilities.

2. There is no acoustic sound produced. The Tinnitus is caused by some type of neural activity different from a person’s heart beat. For example, if a blood vessel is pressing against the auditory nerve connecting the inner ear to the brain, a doctor may not be able to trace the cause of pulsating sound in a person because the disorder affects the hearing related activities of the brain.

Other experts on the disorder say that many of the people suffering from Pulsatile Tinnitus are caused by a chronic inflammation in the inner ear. The increased blood flow damages the delicate tissue present in the ear that causes Patulous Eustachian Tube.

Patulous Eustachian Tube is unusual physical disorder where the Eustachian tube which is normally closed remains sporadically open. When this happens a person may hear his own voice, breathing and heartbeat that vibrate directly into the ear drum. If the tube is infected or injured, fluid builds up in the middle ear that causes Pulsating Tinnitus.

Doctors believe that another cause of Pulsatile Tinnitus is Sinusitis, an inflammation of the paranasal sinuses due to allergies or virus infection. If a person takes more than the prescribed dosage of antibiotics, it will thicken the mucous in the inner ear which needs to be flushed out if not the person may suffer the consequences of a pulsating sound.

Hypothyroidism also causes Pulsating Tinnitus because it causes the heart to beat faster causing a pulsating noise. Other causes include diabetes, hypertension, too much stress in a person’s daily life, lack of rest and exercise.

You must understand that Pulsatile Tinnitus is a common disorder for many people especially among senior citizens. This condition can be prevented and there are available treatments.

A person suffering from Pulsating Tinnitus should be examined by an ENT to pin point the possible cause of the disorder. The doctor will be able to listen to the pulsating sound in and around the ear by using a stethoscope or through a minute electronic microphone placed inside the ear canal called Ausculscope.

If the doctor is able to diagnose the cause of a person’s Pulsatile Tinnitus, he will be able to advice the patient with treatment options and preventive measures.
