When you hear a sound in your ear and it neither repeats frequently nor disappears completely, you are most likely to have pulsatile tinnitus which is an objective tinnitus. At times, an abnormal group of arteries and veins occur inside the cranial cavity near the auditory nerve. Some pregnant women, anemic patients or people having thyroid problem may develop an increase in blood flow in their jugular, the largest vein that takes blood from brain back to heart.
Cholesterol buildup on arterial walls may result in contraction of the artery which blocks the normal flow of blood causing an unpleasant sound in the ear.
Middle ear is usually occupied by air, but when one develops fluid in this area due to the infection of the Eustachian tube, the person may develop pulsatile tinnitus. Sometimes hearing aids are used because they increase external noise, so that the tinnitus sound is less noticed. Medical specialists often prescribe anti-depressants because tinnitus can be associated with anxiety and depression. Lack of nutritious value can be one of the causes of pulsatile tinnitus, thus, vitamin enriched diet can be great treatment to relive the symptoms. I hope you find this article helpful enough to get rid of the irritating issue of pulsatile tinnitus and lead a life with peace of mind. Inner ear disorders that increase hearing sensitivity (such as SCD) can cause pulsatile tinnitus. There are some very large blood vessels -- the carotid artery and the jugular vein -- that are very close to the inner ear (see diagram above). This is a congenital anomaly in which the internal carotid can present as a middle ear mass.
Dural Arteriovenous fistulae (DAVF) cause loud noises, synchronous with the pulse, that can often be heard by others with a stethescope, or sometimes by simply putting one's ear next to the person's head. To be certain there is no DAVF at all, 6 vessel DSA is suggested by the interventional radiologists.
Radiosurgery is mainly reserved for cases that persist after embolization, but some authors use the opposite order -- radiosurgery first, followed by a clean up embolization (e.g. Recurrence of fistulae may appear, possibly due to release of growth factors associated with local tissue hypoxia, following occlusion of the DAVF. It may seem silly to say this, but in our opinion, it is generally not worth taking on a significant risk of having a stroke to attempt to get rid of a noise in one's head with embolization. When a fistula forms, blood from an artery under high pressure and flow goes directly into a vein, which is a low pressure and low flow structure.  Even though the fistula is not directly on or within the brain, it can nevertheless lead to brain dysfunction by congesting the brain venous system, as will be explained below.
Finally, many patients who have dural fistulas of all sizes and locations can have a myriad of symptoms such as different kinds of headache, tiredness, loss of concentration, memory problems, even hallucinations, psychosis or other psychiatric problems.  Unfortunately, in these patients the diagnosis of dural fistula can be significantly delayed because dural fistulas are relatively rare, while the above symptoms are very common and usually not due to a fistula. For an in-depth presentation on treatment of Brain Dural AV Fistulas, primarily geared towards neurointerventional professionals, you can visit Techniques: Brain Dural AV Fistula Embolization page.
Below are pictorial diagrams of what a fistula is like and how it can be treated.  The actual anatomy is much more complicated, but the pictures provide a frame of reference. Finally, post-embolization views, showing the coils in the cavernous sinus (white arrows) and no evidence of fistula on injections of the external carotid artery (brown arrows).  This approach, though technically challenging, can be quite successful when other venues prove unfeasible.


This patient developed a fistula on the dural covering that separates the back part of the brain, called cerebellum, from the overlying occipital lobe. MRA images (top) and stereo MRA composite (MIP) images on the bottom, demonstrating multiple intracranial and extracranial vessels (red arrows) feeding the fistula. The microcatheter has been positioned into another branch of the middle meningeal artery, showing residual fistula and aneurysm.  More glue is injected from this position. Post-embolization views of the left common carotid artery, showing that the fistula is gone.
For an effective treatment for pulsatile tinnitus, it is necessary to know the symptoms and causes of pulsatile tinnitus. Pulsation of these nerves against the auditory nerve may stimulate the nerve ultimately followed by pulsating tinnitus, being one of the main causes. Some antibiotics, antihistamines, anticonvulsant and cardiovascular drugs are also used to cure tinnitus causing infections.
By taking its extract, the patient will improve blood flow to ultimately cure tinnitus treatment. If the carotid fails to develop correctly during fetal life, the inferior tympanic artery enlarges to take it's place. DAVF recieve blood through meningeal arteries or meningeal branches of cerebral arteries and drain directly through a dural sinus or venous channel tributary of a venous sinus through dilated deep veins (Signorelli et al, 2014). The Cognard states that type I and II DAVFs drain directly into dural sinuses, the difference being antegrade flow in the type I, and retrograde flow in the type II.
Successful treatment requires occlusion of the venous recipient, as occlusion of the arteries alone can be associated with recruitment of more venous drainage (Adamczyk et al, 2012).
Surgery is sometimes preferred for fistulae draining into the superior sagittal or dominant transverse sinus when embolization might result in an undesirable sacrifice of the dural venous sinus. Our group at the NYU Langone Medical Center is one of the premier neurointerventional centers in the world.
When a fistula forms between an artery and a vein within the dura, it is called Brain Dural Fistula, or Brain Dural Arteriovenous Fistula, or BDAVF, etc. The total amount of radiation delivered to the patient at conclusion of a dynamic CT scan, however, can be VERY high — in some cases resulting in (usually temporary) hair loss. The bottom picture is venogram obtained by directly injecting the cavernous sinus to demonstrate the basal vein (dark blue) and ophthalmic vein (light blue arrows).  Some coils have already been placed into the sinus.
External and middle ear diseases: Radiological diagnosis based on clinical signs and symptoms.
Computed tomography and magnetic resonance imaging of pathologic conditions of the middle ear.
Accordingly, other possibilities for vascular tinnitus include dehiscence (missing bone) of the jugular bulb -- an area in the skull which contains the jugular vein, and an aberrantly located carotid artery. It enters the skull through it's own foramen, courses through the medial part of the middle ear, and then rejoins the petrous ICA (Branstetter and Weissman, 2006).
DAVF are thought to be acquired and are associated with intracranial surgery, ear infection, tumor, hypercoagulability, puerperium, and trauma.


According to De Keukeleire et al (2011), Type I DAVs are low risk and need be treated only if symptoms are intolerable.
The reason for this order is that embolization might obscure the target for the radiosurgery if performed first. The details of any treatment are best discussed with the specialist performing the procedure.
Temporal bone imaging is challenging and involves deep understanding of the anatomy, especially in relation to High Resolution Computed Tomography (HRCT) imaging. An enlarged jugular bulb on the involved side is common in persons with venous type pulsatile tinnitus. Radiosurgery by itself has a low succes rate as the only treatment (Signorellli et al, 2014). To avoid conflicts of interest, ideally the expert should work for another medical insitution. Cross-sectional imaging has evolved rapidly and has surpassed the radiography and plain film tomography.
Trans venous embolization is a good option when arterial feedrs are too numerous, and when the venous drainage of the DAVF can be sacrifised. It is also a poor choice for those with hemmorage, because it is slow acting (1-3 years), and more hemmorage might occur while waiting for the blood vessels to close. The risk of hemmorage increases with direct drainage into cortical veins (Signorelli et al, 2014). On the other hand, radiosurgery is likely a more durable long term treatment than embolization alone. Middle ear disease can present as ear pain, otorrohea, hearing impairment and other symptoms. In certain cases, routine and contrast-enhanced Magnetic Resonance Imaging (MRI) scores over HRCT in the evaluation of middle ear soft tissue; however, in most instances, it acts as a next step for confirmation and further characterization. Features are consistent with cholesteatomaClick here to viewFigure 4 (A, B): Coronal image of the left temporal bone shows soft tissue opacification in the middle ear, sclerosis of mastoid, non-visualization of the ossicles, erosion of the facial nerve canal, tegmen (white arrows in A and B), lateral mastoid wall, and extension into the inner ear (black arrow). The imaging appearance of facial nerve schwannoma has been described as an enhancing tubular mass (using T1-enhanced MR) within an enlarged facial nerve canal (using CT). The aberrant carotid artery may be dehiscent or may be covered by cortical bone so that the otoscopic examination can sometimes be normal.
A jugular bulb is considered "high riding" if it extends above the level of the floor of the internal auditory canal (IAC). It is always important to make a note about the extent of the disease, anatomical variants, and possible complications.
