What is the most common cause of pulsatile tinnitus
The sensation of hearing a rhythmic noise in one’s ear, which frequently beats in time with one’s pulse, is known as pulsatile tinnitus and is typically brought on by a physical sound source inside or around the ear.
The underlying causes typically fall under the umbrella of vascular issues, which affect the veins and arteries, even if there isn’t one single “most common” cause.
Common causes include
Anomalies in the blood vessels or blood flow in the head and neck, such as atherosclerosis (hardening of the arteries), which causes the blood to flow with more noise or irregularity.
Hypertension, or high blood pressure, may cause the blood to flow more forcefully and thus be more noticeable.
vascular disorders such as arteriovenous malformations or dural arteriovenous fistulas, which involve aberrant connections between arteries and veins.
Greater fluid pressure around the brain (idiopathic intracranial hypertension).
Some tumors that can impact blood vessels and are located close to the ear or neck.
The ear’s bones are thinning, making it easier to hear the sounds of blood moving.
Important Note: Due to the possibility that pulsatile tinnitus may occasionally indicate a more severe underlying medical issue, it is imperative to seek medical attention in order to receive an accurate diagnosis and treatment.

Ear pulsating noise
Ear pulsating noise is the rare form of the ear noise. People with pulseable noise in their ears will hear strong or soft noises, but often occur over time with their heart rate. Just like ear noise, pulsating noise in the ear is not a condition. It is a symptom of a condition such as heart disease or illness that affects your veins and arteries.
What does pulsatile tinnitus mean?
The condition known as pulsatile tinnitus is an uncommon kind of tinnitus. Individuals with tinnitus, often called “TIN-nite-us” or “TIN-e-tus,” may experience persistent sounds in their minds that are audible to nobody else. It is frequently, but not always, referred to as a ringing sound. The sound that individuals with pulsatile tinnitus hear may be loud or faint, but it often occurs at the same time as their heartbeat or sounds like a whoosh. Similar to non-pulsatile tinnitus, pulsatile tinnitus is not a disease. It’s a sign of other illnesses. Pulsatile tinnitus is often a sign of vascular illness, which affects your arteries and veins, as well as aberrant blood flow or malformations in vascular structures close to your ear, and in some uncommon cases, tumors.
What impact does pulsatile tinnitus have on my body?
Pulsatile tinnitus can interfere with your ability to concentrate, sleep, or work, similar to tinnitus. A few individuals experience depression or anxiety as a result of their pulsatile tinnitus or tinnitus. More crucially, pulsatile tinnitus might be a sign that you have a significant medical issue.

Contact your healthcare provider right away if you experience any unexpected or sudden changes in your body. Call your provider right away if you experience any problems, such as balance issues, vision problems, or trouble walking, or if you suddenly hear a rhythmic swooshing sound in your head or in one ear.
Is pulsatile tinnitus prevalent?
Only about 10% of the estimated 50 million tinnitus sufferers experience pulsatile tinnitus, which is an uncommon illness.

Causes and Symptoms
What are the signs of pulsatile tinnitus?
The most typical indication of pulsating tinnitus is a rhythmic whooshing or swooshing sound in your head that frequently matches your pulse. Usually, this involves blood pumping more quickly than usual via numerous veins and arteries that are close to your ears. This could involve smaller arteries in your ears as well as major arteries or veins in your neck and at the base of your skull. People with pulsatile tinnitus can experience their heart pounding, in a sense.
What are the causes of pulsating tinnitus?
The majority of cases of pulsatile tinnitus occur when the blood flow in blood arteries close to or around the ears is altered by specific illnesses or abnormalities. A change in blood flow might be a sign of a severe medical problem at times. Simply having pulsatile tinnitus does not indicate that you have any of these illnesses.
Sometimes, pulsatile tinnitus is caused by an increased sensitivity to the sounds of blood flow, rather than by a change in the blood flow itself.
Conditions that can lead to pulsatile tinnitus include the following:
Atherosclerosis is the hardening of your arteries, which can result in irregular blood flow. Uneven blood flow makes more noise than smooth-flowing blood through arteries near your ear, just like silent rivers that turn into a series of loud rapids.
Sinus wall abnormalities (SWAA): Your sinus wall is a channel on the side of your brain that receives blood from veins within your brain. The whooshing sound associated with pulsatile tinnitus is brought on by conditions that increase blood flow inside this channel.
These are tangles of blood vessels that affect the connections between your arteries and veins. You may have pulsatile tinnitus if you have an arteriovenous malformation close to your ears.
High blood pressure is measured by the force of blood against the walls of your blood vessels. You may have high blood pressure that causes pulsatile tinnitus if that pressure is too high.
Anemia: Anemia can cause pulsatile tinnitus by increasing blood flow, which may have an impact on your blood vessels.
Tumors in the middle ear: Some individuals have tiny tumors in their middle ears that are close to the areas of the ear that collect sound. These are tumors of the glomus with a lot of blood vessels. The sound of blood coursing through the blood vessels of a glomus tumor can occasionally cause someone to experience pulsatile tinnitus.
Idiopathic intracranial hypertension: This occurs when cerebrospinal fluid accumulates around your brain, causing pressure on your blood vessels and perhaps impairing blood flow.
About 53% of those with traumatic head injuries experience tinnitus, including pulsatile tinnitus.
Hyperthyroidism: Your heart may beat more quickly as a result of this illness, which increases blood flow.
Paget’s disease: This condition is a persistent bone ailment that can impact the head. Approximately 20% of those with Paget’s disease have auditory symptoms, such as pulsatile tinnitus.
