Issues with the left ear?
Hello Doctor: I have been hearing a heartbeat sound in my left ear for the past few days, and as a result, I can't sleep.
What could be the cause of this? Is it related to my thyroid?

Dear Ms.
Huang,
There are many causes of pulsatile tinnitus (tinnitus that is synchronized with the heartbeat), with common ones including arteriovenous malformations in the ear or brain, tympanic membrane or jugular vein hemangiomas, high carotid artery position, residual stapedial artery, carotid artery wall defects, and even hypertension.
The next time you hear this sound, you might try changing the position of your head or gently pressing on the side of your neck to see if it becomes quieter.
If this is indeed the case, I recommend that you promptly visit our ENT outpatient department for a detailed examination to identify the underlying cause.
Sincerely,
Dr.

More Info
Pulsatile tinnitus, which you are experiencing as a heartbeat-like sound in your left ear, can be quite distressing and may disrupt your sleep. This condition is characterized by hearing a rhythmic sound that often coincides with your heartbeat. There are several potential causes for pulsatile tinnitus, and understanding these can help you address your concerns.
One common cause of pulsatile tinnitus is vascular issues. This can include abnormalities in blood vessels near the ear, such as arteriovenous malformations or increased blood flow in the vessels due to conditions like hypertension. These vascular changes can create a sound that is perceived as pulsatile tinnitus. Additionally, conditions such as atherosclerosis, where arteries become narrowed or hardened, can also lead to this phenomenon, especially in older adults.
Another possible cause is increased intracranial pressure, which can occur due to various medical conditions, including tumors, idiopathic intracranial hypertension, or even certain types of infections. This increased pressure can affect the blood flow in the vessels near the ear, leading to the perception of pulsatile sounds.
In some cases, pulsatile tinnitus can be related to ear conditions, such as middle ear infections or Eustachian tube dysfunction. These conditions can affect the normal functioning of the ear and lead to abnormal sound perception.
Regarding your question about the thyroid gland, while thyroid disorders can lead to various symptoms, they are not typically directly associated with pulsatile tinnitus. However, hyperthyroidism can increase metabolism and blood flow, which might indirectly contribute to the perception of pulsatile sounds in some individuals.
Given your symptoms, it is essential to consult with a healthcare professional who specializes in ear disorders, such as an otolaryngologist (ENT specialist). They can perform a thorough examination, which may include imaging studies like an MRI or CT scan, to rule out any underlying vascular or structural issues.
In the meantime, there are a few strategies you can employ to manage your symptoms. Stress management techniques, such as mindfulness or relaxation exercises, can help reduce the perception of tinnitus. Additionally, using white noise machines or soft music while sleeping may help mask the sound and improve your ability to rest.
In summary, pulsatile tinnitus can arise from various causes, including vascular issues, increased intracranial pressure, or ear-related conditions. While it is unlikely to be directly related to thyroid function, it is crucial to seek medical advice for a proper diagnosis and treatment plan. Your well-being is important, especially as you prepare for your future career as a pilot, where optimal hearing is essential.
