Why does pulsatile tinnitus come and go?
Pulsatile tinnitus is a specific, and potentially serious, form of tinnitus: the person hears a rhythmic sound—often described as whooshing, beating, or pulsing—usually synchronized with their heartbeat. Unlike more common, continuous or high-pitched tinnitus, pulsatile tinnitus is most often of vascular origin. For some, it is only slightly irritating; for others, it becomes disabling and disrupts sleep, concentration, and general well-being.
IMPORTANT: pulsatile tinnitus should never be ignored. It may be benign, but it is frequently a symptom of an underlying vascular or neurological condition—including tumors—and must always be subject to a medical assessment.
Symptoms of pulsatile tinnitus
The hallmark symptom of pulsatile tinnitus is a sound that beats in time with the heart, often louder when the heart rate increases (physical exertion, stress, etc.). This sound can:
Be present in one ear or both
Come and go, or be permanent
Be more noticeable at night, when ambient noise is low
Causes of pulsatile tinnitus
Pulsatile tinnitus almost always has an identifiable cause. Some are benign, while others can be life-threatening. A medical assessment is essential.
Common causes:
Atherosclerosis: narrowed or hardened arteries create turbulent blood flow near the ear.
High blood pressure: this can increase blood flow turbulence and make pulsations audible.
Blood vessel abnormalities: arteriovenous malformations (AVMs), aneurysms, or vascular stenoses near the auditory system.
Idiopathic intracranial hypertension (IIH): excessive pressure of the cerebrospinal fluid around the brain, often seen in young women and associated with headaches, vision problems, and pulsatile tinnitus.
Superior canal dehiscence syndrome (SCDS): a bony defect in the inner ear that leads to abnormal transmission of internal sounds.
Sigmoid sinus diverticulum or dehiscence: structural abnormalities near the venous sinuses of the brain.
Tumors that can cause pulsatile tinnitus:
The tumor hypothesis must be considered in all cases of pulsatile tinnitus, especially if the sound affects only one side or if it worsens.
Glomus tumors (paragangliomas): benign but locally invasive tumors located near the middle ear or the jugular bulb. These are the tumors most often associated with pulsatile tinnitus.
Vestibular schwannoma (acoustic neuroma): it usually causes non-pulsatile tinnitus, but can affect vascular structures and lead to pulsations.
Meningiomas or skull base tumors: they can compress vascular or nerve structures and cause pulsatile tinnitus.
Other possible causes:
Anemia
Hyperthyroidism
Head trauma
Conductive hearing loss (linked, for example, to an effusion or an ear infection)
Diagnosing pulsatile tinnitus
A thorough medical assessment is unavoidable if you suffer from pulsatile tinnitus.
This assessment should start with an ENT (ear, nose, and throat) specialist, who can carry out:
A complete history and physical examination
Cardiovascular and neurological evaluations
An otoscopic examination
Blood pressure measurement and biological analyses
Imaging tests are essential to rule out a vascular abnormality or a tumor:
MRI and/or MRA (magnetic resonance angiography)
CT scan and/or CT angiography
Temporal bone CT scan
Doppler ultrasound (of the neck vessels)
Your doctor may also prescribe blood tests to check for anemia, a thyroid disorder, or signs of infection.
Why pulsatile tinnitus comes and goes
Many people report that their pulsatile tinnitus varies in intensity, frequency, and volume. This is confusing and often distressing.
Even when the underlying cause remains the same, different factors can worsen (or temporarily relieve) the perception of pulsatile tinnitus:
Variations in blood pressure
Stress or anxiety
Lack of sleep
Caffeine or high salt intake
Dehydration
Certain medications or dietary supplements
Body position (lying down can intensify the perception)
These "spikes" or fluctuations are called tinnitus exacerbations. While they do not always reflect a worsening of the underlying condition, they make the symptoms harder to bear.
How to identify the causes of your tinnitus fluctuations
Tracking your symptoms is one of the most useful tools for managing pulsatile tinnitus. Keep a journal in which you note:
Times of day when the tinnitus is noticeable
What you ate, drank, or did before it worsened
Your stress, hydration, and sleep levels
Any new medication or dietary supplement
Look for recurring patterns. Identifying your triggers can help limit the spikes, but always in parallel with medical follow-up.
Treatment options
Treatment depends entirely on the underlying cause, hence the importance of the diagnosis.
If a tumor or vascular malformation is identified, treatment may involve surgery, radiation therapy, or embolization.
If the cause is high blood pressure or IIH, medical management of blood pressure or intracranial pressure can improve symptoms.
In case of anemia or thyroid dysfunction, correcting the metabolic imbalance can make the tinnitus disappear.
If a structural abnormality is found (a sigmoid sinus diverticulum, for example), surgical correction is sometimes possible.
If no serious condition is detected, sound therapy, stress reduction, and hearing aids with masking features can reduce the perception of pulsatile tinnitus.
In conclusion: take pulsatile tinnitus seriously
Pulsatile tinnitus is not just "in your head." It is your body signaling that something might be wrong—sometimes seriously.
Not all pulsatile tinnitus is dangerous, but some is the first sign of a tumor or a vascular abnormality. This is why it should never be taken lightly, especially if it persists, worsens, or affects only one ear.
If you suffer from pulsatile tinnitus, consult an ENT or neurologist as soon as possible. Early diagnosis can save your life.
If you have already received a diagnosis and wish to manage the fluctuations on a daily basis, tools such as a tracking journal, sound therapy, and lifestyle changes can help, but no at-home strategy replaces professional follow-up.
