If you hear a rhythmic whooshing, thumping, or pulsing sound in one or both ears that beats in time with your heartbeat, you may be experiencing pulsatile tinnitus. Unlike the more common form of tinnitus—which typically presents as a constant ringing or buzzing—pulsatile tinnitus is a distinct condition with identifiable, and often treatable, underlying causes.
As a cerebrovascular and endovascular neurosurgeon who has treated hundreds of patients with pulsatile tinnitus and helped develop a multidisciplinary pulsatile tinnitus program, I want to share what patients should know about this condition, including when to seek specialized evaluation and what treatment options are available.
Pulsatile Tinnitus Is Different from Regular Tinnitus
Most tinnitus—the ringing or buzzing that affects millions of people—originates from damage to the tiny hair cells in the inner ear and is often related to noise exposure, aging, or hearing loss. Pulsatile tinnitus, however, is usually caused by a change in blood flow in the vessels near the ear, or by an increased awareness of blood flow in that region. Because the sound corresponds to your pulse, it is often described as hearing your heartbeat in your ear.
This distinction matters enormously because pulsatile tinnitus can be a sign of an underlying vascular condition—some of which carry real health risks if left untreated.
What Causes Pulsatile Tinnitus?
There are several potential causes, which is why a thorough evaluation by a specialist is important. Common causes include:
- Dural arteriovenous fistula (dAVF): An abnormal connection between arteries and veins in the covering of the brain. This is one of the most important causes to identify because dAVFs can carry a risk of bleeding or stroke if left untreated. Endovascular treatment can often provide a complete cure.
- Venous sinus stenosis: A narrowing of the large veins that drain blood from the brain. This can create turbulent blood flow that you hear as a pulsing sound. It is often associated with idiopathic intracranial hypertension (IIH) and can be treated with venous sinus stenting.
- Venous sinus diverticulum: A small outpouching of a venous sinus, frequently found near the ear, that creates turbulent flow. Endovascular treatment can resolve symptoms.
- Idiopathic intracranial hypertension (IIH): Elevated pressure around the brain that can cause pulsatile tinnitus, headaches, and vision problems. Treatment may include medication, weight management, shunting, or venous sinus stenting.
- Atherosclerotic carotid disease: Buildup of plaque in the carotid arteries in the neck can create turbulent flow that you hear as pulsatile tinnitus.
- Paraganglioma (glomus tumor): A rare, usually benign tumor that grows near the ear and is rich in blood vessels. Treatment may involve surgery, embolization, or observation.
- Other vascular causes: These include arteriovenous malformations, high-riding jugular bulb, and vascular anomalies near the temporal bone.
When Should You See a Specialist?
If you experience pulsatile tinnitus—especially if it is persistent, worsening, or accompanied by headaches, vision changes, or hearing loss—you should seek evaluation from a physician experienced in diagnosing vascular causes. Many patients see multiple doctors before the underlying cause is identified, and unfortunately, pulsatile tinnitus is sometimes dismissed as “just tinnitus” without adequate investigation.
“I encourage patients to advocate for themselves. Pulsatile tinnitus is not something you simply have to live with. In the majority of cases, we can identify the cause and offer effective treatment.” — Dr. Omar Choudhri
How Is Pulsatile Tinnitus Diagnosed?
A proper workup should include a thorough physical examination and targeted imaging. Research published by our team has helped define an evidence-based diagnostic approach for pulsatile tinnitus. The imaging workup typically involves:
- MRI and MRA of the brain: To evaluate the brain structures and blood vessels for abnormalities.
- CT angiography (CTA): To provide detailed images of the arteries and veins near the skull base and ear.
- Catheter-based cerebral angiography: The gold standard for identifying dural fistulas, venous stenosis, and other vascular abnormalities. This minimally invasive procedure, which can often be performed through the wrist, provides the highest-resolution view of the blood vessels in the brain.
In some cases, advanced techniques such as balloon-assisted retrograde cerebral phlebography—a specialized imaging technique used to evaluate the veins of the brain—may be needed to fully characterize the underlying pathology.
Treatment Options
Treatment depends entirely on the underlying cause. The encouraging news is that many causes of pulsatile tinnitus are highly treatable:
- Endovascular treatment: For dural fistulas, venous sinus stenosis, and venous diverticula, minimally invasive catheter-based procedures can often provide a complete cure. These procedures are typically performed through a small puncture in the wrist, with most patients going home within one to two days.
- Microsurgery: In select cases, open surgical treatment may be recommended, particularly for complex dural fistulas or tumors.
- Medical management: For conditions like IIH, medications to reduce intracranial pressure, along with lifestyle modifications, may be the first line of treatment.
- Observation: Some causes, when confirmed to be low-risk, can be safely monitored with periodic imaging.
Finding the Right Specialist
Pulsatile tinnitus sits at the intersection of neurosurgery, neuroradiology, and otolaryngology, which means the most effective evaluation often comes from a multidisciplinary team. I have worked closely with ENT colleagues to build a dedicated pulsatile tinnitus program that provides comprehensive evaluation, advanced imaging, and specialized treatment options under one coordinated care team.
If you or someone you know is living with pulsatile tinnitus, I encourage you to seek a thorough evaluation. A proper diagnosis is the first step toward finding relief.
