Carotid plaque can cause dizziness, but it does not usually cause a feeling of ear blockage.
If the carotid plaque is small or causes a stenosis of less than 30% of the blood vessels, the body can often compensate for it, and can generally still carry out normal activities and rest without any symptoms, and the lesion can only be detected by means of ultrasound examination of the blood vessels of the neck.
When carotid plaque causes a bilateral stenosis of more than 50%, or a unilateral stenosis of more than 75%, the patient may experience dizziness.
Carotid artery stenosis does not usually lead to a feeling of ear blockage, which is often associated with a number of pathologies of the external ear canal, the eardrum, the middle ear, and the inner ear, such as inflammation of the external auditory canal, cerumen embolism, otitis media, cholesteatoma, and Ménière’s disease.
When these diseases of the ear coexist with carotid plaque, patients can feel dizzy and ear blockage; in addition, Meniere’s disease itself has symptoms of dizziness and ear blockage at the same time.
In addition to the above causes, other factors can also lead to dizziness and ear blockage. If the symptoms continue to be unrelieved, please consult a doctor in time to avoid delaying the condition.
