How to Check for Pulsatile Tinnitus?
Discover the methods to reliably determine if you have pulsatile tinnitus, the rhythmic whooshing or throbbing sound in your ears that matches your heartbeat. This guide provides a comprehensive overview of self-assessment techniques and professional evaluations.
Understanding Pulsatile Tinnitus
Pulsatile tinnitus is a unique form of tinnitus characterized by a rhythmic sound in the ear that synchronizes with the heartbeat. Unlike subjective tinnitus, which is often a high-pitched ringing and is typically caused by inner ear issues, pulsatile tinnitus usually stems from changes in blood flow within or near the ear. These changes can be due to various factors, ranging from benign causes like increased blood flow during pregnancy or anemia, to more serious conditions such as vascular tumors, arteriovenous malformations, or increased intracranial pressure. The perceived sound can vary from a gentle whooshing to a loud thumping or throbbing.
Self-Assessment Techniques: Initial Checks
Before seeking professional help, there are several self-assessment techniques you can employ to gain a better understanding of your symptoms and prepare for a consultation.
- Identify the Sound: Confirm that the sound is rhythmic and in sync with your pulse. Take your pulse on your wrist and compare it to the sound in your ear. A consistent match suggests pulsatile tinnitus.
- Unilateral or Bilateral: Determine if the sound is in one ear (unilateral) or both (bilateral). Unilateral pulsatile tinnitus is often associated with more specific underlying causes, requiring further investigation. Bilateral pulsatile tinnitus can be related to systemic issues.
- Positional Changes: Pay attention to whether the sound changes with head position or lying down. Certain positions might increase or decrease the intensity of the sound, providing clues about the source of the tinnitus.
- Pressure Maneuvers: Gently press on your neck on the side where you hear the sound. Sometimes, pressing on the jugular vein can temporarily stop or diminish the sound if it is caused by a vascular abnormality in that area. Never apply excessive pressure.
Professional Evaluation: When to Seek Help
While self-assessment can be helpful, it is crucial to seek professional evaluation from a qualified healthcare provider. An audiologist or an otolaryngologist (ENT doctor) are typically the best specialists to consult. You should especially seek immediate medical attention if you experience any of the following:
- Sudden onset of pulsatile tinnitus.
- Accompanying neurological symptoms, such as headaches, dizziness, blurred vision, or weakness.
- Pulsatile tinnitus after a head injury.
- Unilateral pulsatile tinnitus.
- Persistent and disruptive pulsatile tinnitus affecting your quality of life.
Diagnostic Tests: What to Expect
A thorough evaluation will involve a combination of medical history review, physical examination, and diagnostic testing. These tests aim to identify the underlying cause of the pulsatile tinnitus. Common diagnostic tests include:
- Audiometry: This test assesses your hearing thresholds and rules out other forms of tinnitus.
- Magnetic Resonance Angiography (MRA) or Computed Tomography Angiography (CTA): These imaging techniques visualize blood vessels and identify any abnormalities, such as arteriovenous malformations or aneurysms.
- Magnetic Resonance Imaging (MRI): MRI can provide detailed images of the brain and surrounding tissues, helping to rule out tumors or other structural abnormalities.
- Ultrasound (Doppler): This non-invasive test can assess blood flow in the neck and head.
- Cerebral Angiogram: In some cases, a cerebral angiogram, an invasive procedure involving injecting contrast dye into blood vessels, may be necessary to visualize the blood vessels more clearly.
Treatment Options: Addressing the Underlying Cause
Treatment for pulsatile tinnitus focuses on addressing the underlying cause. If the tinnitus is due to a benign condition, such as anemia or high blood pressure, treating these conditions can resolve the tinnitus. In cases of vascular abnormalities or tumors, surgery or other interventions may be required. In some instances, a cause may not be found, and management strategies to help cope with the tinnitus may be suggested.
Common Mistakes: What to Avoid
When trying to check for pulsatile tinnitus it’s important to avoid these common mistakes:
- Self-diagnosing: While self-assessment is useful, relying solely on internet information for diagnosis can be misleading and dangerous. Always consult a healthcare professional.
- Ignoring other symptoms: Pay attention to any other symptoms you are experiencing and report them to your doctor. Do not dismiss seemingly unrelated symptoms.
- Delaying treatment: If you suspect you have pulsatile tinnitus, seek medical attention promptly. Early diagnosis and treatment can prevent complications and improve your quality of life.
- Overly relying on home remedies: While some people find relief from relaxation techniques, they are not a substitute for medical evaluation and treatment.

Frequently Asked Questions (FAQs)
Is pulsatile tinnitus always serious?
No, pulsatile tinnitus is not always serious. In some cases, it can be caused by benign conditions like pregnancy, anemia, or high blood pressure. However, it can also be a sign of more serious underlying issues such as vascular abnormalities or tumors, necessitating medical evaluation to determine the root cause.
How can I tell if my tinnitus is pulsatile?
The key indicator of pulsatile tinnitus is that the sound matches your heartbeat. Take your pulse and see if the sound in your ear is synchronized. If it is a constant ringing or buzzing that doesn’t match your pulse, it is more likely regular tinnitus.
Can stress cause pulsatile tinnitus?
While stress can exacerbate many conditions, it is not a direct cause of pulsatile tinnitus. However, stress can raise your blood pressure, which, in some cases, could make existing pulsatile tinnitus more noticeable. Managing stress may help alleviate symptoms.
What kind of doctor should I see if I suspect I have pulsatile tinnitus?
The best doctors to consult are an audiologist or an otolaryngologist (ENT doctor). They have the expertise to properly evaluate your condition and determine the underlying cause.
What does an MRA or CTA show?
MRA (Magnetic Resonance Angiography) and CTA (Computed Tomography Angiography) are imaging tests that visualize blood vessels. They can reveal abnormalities such as arteriovenous malformations (AVMs), aneurysms, or narrowed blood vessels, which can contribute to pulsatile tinnitus.
Is there a cure for pulsatile tinnitus?
The possibility of a cure depends entirely on the underlying cause. If the cause can be identified and treated, the pulsatile tinnitus often resolves. However, if a cause is not found or cannot be directly treated, management strategies can help cope with the symptoms.
Can pulsatile tinnitus affect my hearing?
In some cases, yes. If the underlying cause of the pulsatile tinnitus, such as a vascular tumor pressing on the auditory nerve, impacts the hearing pathways, it can lead to hearing loss.
Are there any medications that can help pulsatile tinnitus?
There are no specific medications that directly treat pulsatile tinnitus itself. Instead, medications may be used to address underlying conditions, such as blood pressure medications for hypertension or iron supplements for anemia.
What if no cause is found for my pulsatile tinnitus?
Even if no specific cause is identified, there are management strategies that can help you cope with the symptoms. These include sound therapy, cognitive behavioral therapy (CBT), and relaxation techniques.
Are there any lifestyle changes that can help with pulsatile tinnitus?
Maintaining a healthy lifestyle can be beneficial. This includes managing blood pressure, reducing stress, avoiding excessive caffeine and alcohol, and staying hydrated. Regular exercise can also improve overall vascular health.
Does pulsatile tinnitus get worse over time?
The progression of pulsatile tinnitus varies depending on the underlying cause. In some cases, it may remain stable, while in others, it may worsen over time if the underlying condition progresses. Regular follow-up with your doctor is essential. This is why how to check for pulsatile tinnitus regularly can be beneficial.
How accurate are the self-assessment techniques for pulsatile tinnitus?
Self-assessment techniques can provide initial clues, but they are not a substitute for professional evaluation. They help you gather information to share with your doctor but are not conclusive for diagnosis. The purpose of how to check for pulsatile tinnitus at home is to gather information, not to definitively diagnose.
