Eustachian tube dysfunction can cause pulsatile tinnitus, though the connection is more specific than many people realize. The type most strongly linked to hearing your own heartbeat is called patulous Eustachian tube dysfunction, where the tube stays abnormally open instead of closed. In a study of patients with this condition, about 17% reported pulsatile tinnitus as one of their symptoms. The mechanism involves the tube acting as an open channel that transmits vascular sounds from deep in the skull directly into the middle ear.
How the Eustachian Tube Becomes a Sound Tunnel
The Eustachian tube connects the middle ear to the back of the throat. Normally it stays closed and opens briefly when you swallow, yawn, or equalize pressure. When it functions correctly, it keeps your middle ear sealed off from the noise your body generates internally. But when the tube is stuck open or behaves abnormally, that seal breaks down.
The tube and the space around it in the back of the throat form what researchers have described as an acoustic passageway for sounds that originate inside the body. These include the sound of your own voice, breathing, chewing, and your heartbeat.1PubMed. The pharyngeal recess/Eustachian tube complex forms an acoustic passageway Under normal circumstances, these sounds are dampened by the closed tube. When the tube remains open, they travel freely into the middle ear, where they are picked up by the eardrum and perceived as sound. The heartbeat, because it produces a rhythmic vascular pulse, gets heard as pulsatile tinnitus: a whooshing or thumping that keeps time with your pulse.
Patulous Eustachian Tube and Its Distinctive Symptoms
The form of Eustachian tube dysfunction most directly tied to pulsatile tinnitus is called a patulous Eustachian tube, meaning the tube is chronically or intermittently gaping open. This is distinct from the far more common type of Eustachian tube dysfunction, where the tube fails to open properly and leaves you feeling clogged or pressurized. With a patulous tube, the problem is the opposite: it opens too much or stays open when it should be closed.
The hallmark symptoms are autophony (hearing your own voice as abnormally loud or echoing inside your head) and hearing your own breathing. In a clinical study looking at the demographics and symptom profiles of patulous Eustachian tube patients, voice autophony was reported by 93%, breath autophony by 92%, aural fullness by 57%, pulsatile tinnitus by 17%, and crackling or rumbling sounds by 14%.2Otology & Neurotology. Patulous Eustachian Tube Dysfunction: Patient Demographics and Comorbidities So while pulsatile tinnitus is not the most common complaint in this population, it is a well-documented one. And because patulous Eustachian tube is itself uncommon, many patients with this type of pulsatile tinnitus go undiagnosed for a long time.
A case report of a 48-year-old woman who developed persistent autophony and the sensation of hearing her own heartbeat and breathing after significant weight loss following bariatric surgery illustrates how the condition presents. Her patulous Eustachian tube dysfunction was directly linked to her pulsatile tinnitus symptoms.3PubMed Central.

The Carotid Artery Sits Remarkably Close to the Tube
One reason the Eustachian tube is so good at transmitting vascular sounds is its intimate relationship with the internal carotid artery, one of the major blood vessels supplying the brain. The two structures run very close to each other inside the skull base, and in some spots they literally share the same bony wall.4PubMed. The anatomical relationship between the eustachian tube and petrous internal carotid artery The junction between the bony and cartilaginous portions of the Eustachian tube sits just in front of the first bend of the internal carotid artery.5PubMed. Eustachian Tube as a Landmark to the Internal Carotid Artery in Endoscopic Skull Base Surgery
This matters because the blood pulsing through the carotid artery produces vibrations. Those vibrations travel through bone and tissue. When only a paper-thin wall of bone separates the artery from the tube, and the tube is gaping open, the sound has an unobstructed path right to your eardrum. Anatomical studies of the skull base consistently find that the wall of the carotid canal lies between the artery and the cartilaginous part of the Eustachian tube.6PubMed. Eustachian tube and internal carotid artery in skull base surgery: an anatomical study In most people, this arrangement is clinically silent. But when the tube’s normal closure mechanism fails, or when the anatomy is slightly atypical, it creates the conditions for pulse-synchronous sound to reach the ear.
When an Unusual Blood Vessel Route Makes Things Worse
Some people have a carotid artery that takes an atypical path through the skull, bringing it even closer to the Eustachian tube opening than normal. This variant, sometimes called an aberrant internal carotid artery, can turn what would normally be a faint, inaudible pulse into a clearly perceived sound. In one documented case, a 74-year-old woman presented with pulsatile tinnitus in her right ear. Imaging revealed that her right internal carotid artery had shifted to a more medial and superficial position and was coursing right next to the opening of the Eustachian tube along its length.7PubMed Central. Pulsatile tinnitus arising from aberrant internal carotid artery at nasopharynx
An endoscopic examination actually showed pulsating swelling of the wall at the back of her throat on that side. This is a scenario where the Eustachian tube is not necessarily dysfunctional in the traditional sense, but the vascular anatomy near the tube is unusual enough to produce pulsatile tinnitus through direct sound transmission. This type of case is rare but important to identify, because it changes treatment decisions entirely. Surgical procedures on the Eustachian tube would not help, and any attempt to intervene in that region without recognizing the aberrant artery could be dangerous.
Where Eustachian Tube Dysfunction Falls in the Bigger Diagnostic Picture
Pulsatile tinnitus has a long list of potential causes, and Eustachian tube dysfunction is just one of them. A differential diagnosis review identifies secondary pulsatile tinnitus causes that include tumors, arteriovenous malformations or fistulas, idiopathic intracranial hypertension, narrowing of the venous sinuses in the brain, middle ear conditions like otosclerosis, patulous Eustachian tube, and bony defects such as superior semicircular canal dehiscence.8Current Pain and Headache Reports / Springer Link. Pulsatile Tinnitus: Differential Diagnosis and Approach to Management
The key distinction for patients is that some causes of pulsatile tinnitus are vascular (involving blood vessels themselves) and some are non-vascular. A patulous Eustachian tube is classified as a non-vascular, otoacoustic cause. The tube is not creating the sound; it is transmitting a sound that already exists (the heartbeat) by failing to block it. This is different from, say, a dural arteriovenous fistula, where an abnormal connection between an artery and a vein generates turbulent blood flow that produces the sound.
This distinction matters because the workup and treatment differ dramatically depending on the underlying cause. Someone with pulsatile tinnitus caused by idiopathic intracranial hypertension may need pressure-lowering medications or venous sinus stenting. Someone with pulsatile tinnitus from a patulous tube needs treatment directed at the tube itself. Getting to the right diagnosis usually requires a combination of clinical examination, hearing tests, and imaging.
Other Forms of Eustachian Tube Dysfunction and Tinnitus
The more common form of Eustachian tube dysfunction, where the tube fails to open adequately, produces a different type of tinnitus. The typical complaints are pressure or fullness in the ear, a clogged or underwater sensation, popping, crackling, and sometimes a ringing or buzzing type of tinnitus that is constant rather than pulse-synchronous.9PubMed Central. Eustachian tube dysfunction: consensus statement on definition, types, clinical presentation and diagnosis This is the kind of tinnitus that often accompanies congestion, ear infections, or altitude changes. It does not typically produce a heartbeat sound.
The mechanism here is different. When the tube cannot open to equalize pressure, negative pressure builds in the middle ear. This can retract the eardrum, cause fluid to accumulate, and alter the way the ear processes sound. The resulting tinnitus tends to be a steady tone or hiss rather than a rhythmic pulsing. Some patients describe it as ringing, while others call it muffled or distant. If you are hearing a constant ring or buzz alongside ear pressure, that points more toward obstructive Eustachian tube dysfunction. If you are hearing a rhythmic thump or whoosh that matches your pulse, a patulous tube or a vascular cause should be on the list.
That said, obstructive Eustachian tube dysfunction can occasionally coexist with conditions that cause pulsatile tinnitus. For instance, someone with chronic middle ear fluid (secretory otitis media) from poor tube function may also have a separate vascular finding. The two problems are not mutually exclusive, even though they produce different types of tinnitus.
Getting the Right Diagnosis
Pulsatile tinnitus warrants a more thorough workup than non-pulsatile tinnitus. A physician hearing that your tinnitus keeps time with your heartbeat will generally want to investigate further, because many causes of pulsatile tinnitus are identifiable and treatable. For Eustachian tube-related pulsatile tinnitus specifically, there are some distinguishing features.
Patulous Eustachian tube dysfunction often produces symptoms that change with position. Many patients notice the heartbeat sound and autophony worsen when they are upright and improve when lying down or bending forward. This happens because gravity affects the tissue around the Eustachian tube opening, and changing position can cause the tube to close partially. Another clue is that sniffing sometimes temporarily relieves symptoms by creating negative pressure that pulls the tube closed. If your pulsatile tinnitus improves when you lie down, or if you also hear your own breathing and voice echoing, a patulous tube is a strong possibility.
Tympanometry, which measures eardrum movement and middle ear pressure, can sometimes reveal characteristic patterns. An endoscopic look at the Eustachian tube opening in the back of the throat may show the tube gaping open or the eardrum moving synchronously with breathing. Imaging studies like CT or MRI angiography are often ordered to rule out vascular causes, and in some cases they reveal the close anatomical relationship between the carotid artery and the Eustachian tube or identify aberrant vascular anatomy.
Treatment Options for Patulous Eustachian Tube
Treating patulous Eustachian tube dysfunction, and the pulsatile tinnitus it causes, ranges from conservative measures to procedural interventions. The goal is to get the tube to stay closed when it should be.
Conservative approaches include weight management (since the condition is associated with weight loss and reduced fat around the tube), staying well hydrated, and sometimes using saline nasal drops to help the tube mucosa swell slightly and maintain closure. Some patients learn behavioral tricks, like sniffing or lowering their head, to temporarily close the tube when symptoms flare. For patients whose obstructive-type Eustachian tube dysfunction has led to middle ear fluid and associated tinnitus, nasal corticosteroid sprays have been shown to help speed recovery of hearing and resolution of tinnitus and ear stuffiness in children with secretory otitis media.10Clinics. Clinical study of the effect of mometasone furoate nasal spray treatment on hearing and in secretory otitis media in children These sprays are not treating a patulous tube directly but can address related inflammation and fluid accumulation.
When conservative measures fail for a patulous tube, procedural options exist. One approach involves injecting a soft-tissue bulking agent near the Eustachian tube opening to partially narrow it. In one study using this technique, 10 out of 15 patients were satisfied with the result, with only three reporting no improvement. The procedure was described as minimally invasive, fast, and straightforward.11PubMed. Treatment of the patulous Eustachian tube with soft-tissue bulking agent injections
Another technique uses injections of the patient’s own fat tissue around the tube opening. A study of 28 patients treated with autologous fat injection found significant improvement in aural fullness, breathing noise, tinnitus, and autophony scores. Twenty patients showed significant improvement and six showed moderate improvement, with no patients getting worse. The overall success rate was about 93%.12PubMed Central. Autologous Fat Injection for the Treatment of Patulous Eustachian Tube The idea behind both approaches is the same: add bulk to the tissue around the tube opening so it does not gape open, restoring the natural barrier that blocks transmission of body sounds to the middle ear.
The Weight Loss Connection
Patulous Eustachian tube dysfunction has a well-recognized association with weight loss. The tissue surrounding the Eustachian tube opening includes a fat pad that helps the tube maintain its resting closed position. When someone loses a significant amount of weight, whether through bariatric surgery, illness, or intentional dieting, this fat pad shrinks. With less tissue bulk holding the tube closed, it falls open more easily.
The bariatric surgery case mentioned earlier illustrates this clearly: a woman developed patulous Eustachian tube symptoms, including hearing her own heartbeat, after losing substantial weight following sleeve gastrectomy.3PubMed Central. Management of patulous Eustachian tube dysfunction following bariatric surgery: a case report This pattern is familiar to ear, nose, and throat specialists. It does not mean that weight loss is harmful; it means that this is a recognized complication that has specific treatments available. If you develop new ear symptoms after losing a lot of weight, particularly if you hear your own breathing or heartbeat, mentioning the weight loss to your doctor can speed up the diagnostic process considerably.
Other associated factors include hormonal changes (the condition is reported more frequently in women, especially during pregnancy or with certain hormonal medications), chronic illness, radiation therapy to the head and neck, and conditions that cause generalized tissue wasting. These all share the common thread of reducing the bulk or tone of the tissue that normally keeps the tube closed.
When Pulsatile Tinnitus Needs Urgent Attention
While a patulous Eustachian tube is not dangerous in itself, pulsatile tinnitus as a symptom can sometimes signal something that needs prompt evaluation. Among the vascular causes, conditions like dural arteriovenous fistulas, intracranial aneurysms, and idiopathic intracranial hypertension can be serious if left untreated. A person cannot self-diagnose the cause of their pulsatile tinnitus, and assuming it is “just” an Eustachian tube issue without proper evaluation is risky.
Red flags that should prompt faster medical attention include pulsatile tinnitus that is only on one side, pulsatile tinnitus accompanied by headaches or vision changes, and pulsatile tinnitus that a doctor can also hear with a stethoscope placed near the ear (called objective pulsatile tinnitus). Sudden onset is also worth taking seriously. If your doctor can hear the pulse-synchronous sound during examination, that raises concern for a vascular source generating actual turbulent flow, as opposed to a patulous tube merely transmitting the normal heartbeat sound. The distinction between these two scenarios is exactly why imaging is a standard part of the pulsatile tinnitus workup.
In practice, many people with pulsatile tinnitus from a patulous Eustachian tube will have reassuringly normal imaging. The condition can be frustrating and distressing, but it is treatable and not inherently dangerous. The challenge is getting to the correct diagnosis, which sometimes requires seeing a specialist familiar with Eustachian tube disorders rather than stopping at a general ENT evaluation that focuses mainly on the more common obstructive type of dysfunction.
