Pulsatile tinnitus is a specific type of tinnitus where a person hears a sound in their ear that is in rhythm with their pulse. The sound is often described as a whooshing, but can also be a clicking, crackling, pinging, or scratching. Unlike regular tinnitus, which is a constant sound, pulsatile tinnitus is a rhythmic noise that can be heard by others, such as a doctor listening with a stethoscope.

Pulsatile tinnitus can be caused by a variety of conditions that affect blood flow in the head and neck, including:

• Atherosclerosis (plaque buildup in the arteries)
• Blood vessel disorders, such as a dural arteriovenous fistula (irregular connection between an artery and vein), aneurysm (bulge), or dissection (tear) in an artery
• Head and neck tumors
• High blood pressure
• Idiopathic intracranial hypertension (increased pressure in the fluid around the brain)
• Narrowing of one of the large veins in the brain

Treatment for pulsatile tinnitus depends on the underlying cause. If a specific condition is identified, such as a blood vessel abnormality, surgery or medication may be recommended to correct the problem. In some cases, lifestyle changes such as weight loss or reducing caffeine intake may be recommended. White noise or other sound therapies may also be helpful in managing symptoms. It is important to see a doctor if you experience pulsatile tinnitus, especially if you have other symptoms such as headaches, dizziness, or vision changes.
