Buzzing in the right ear like a heartbeat is considered to be tinnitus. Tinnitus can be caused by a variety of reasons such as atherosclerosis, aneurysms, hyperthyroidism, anemia, sigmoid sinus lesions, and benign intracranial hypertension syndrome.
Pulsatile tinnitus is characterized by a rhythm of tinnitus that is consistent with the heartbeat, and may be caused by the transmission of sound produced by organs, blood vessels, and other structures in the head and neck to the inner ear through the bone, blood flow, and so on causing tinnitus symptoms in the patient.
Throbbing tinnitus can be categorized into arterial causes such as atherosclerosis and aneurysms, venous causes such as benign intracranial hypertension syndrome and sigmoid sinus lesions, and non-vascular causes such as palatine muscle spasms and tympanic membrane tensor muscle spasms.
General pulsatile tinnitus can be identified through imaging and other methods, and patients are advised to seek timely medical attention to identify the cause and treatment.
