What causes noise in the ears when swallowing saliva?

Some friends feel a ringing sound in their ears when they swallow their saliva. It is possible that the eardrum is affected and causes an echo. There are many reasons for this phenomenon, such as binary diseases, non-otogenic diseases, etc. For friends who have experienced this kind of phenomenon for a long time, they should go to a regular hospital for examination to confirm whether it is a disease and then receive treatment.

Tinnitus refers to the abnormal sound sensation that people experience without any external stimulation. For example, if you feel monotonous or mixed sounds such as cicadas, buzzing, hissing, etc. in your ears, there is actually no corresponding sound in the surrounding environment. In other words, tinnitus is just a subjective feeling. Tinnitus can be short-lived or persistent. Severe tinnitus can disturb a person's peace of mind and make him very nervous. If it is a short-term tinnitus that comes and goes, it is generally a physiological phenomenon. There is no need to be overly nervous and you can just leave it alone. If the tinnitus is persistent, especially if it is accompanied by other symptoms such as deafness, dizziness, and headache, you should be alert and seek medical attention as soon as possible.

What are the causes of tinnitus ?

The causes of tinnitus are relatively complex and can generally be divided into two categories: ① Otogenic diseases (i.e. related to ear diseases). They are often accompanied by hearing loss and are caused by poisoning by ototoxic products, viral infections, insufficient blood supply to the inner ear, etc. ② Non-otogenic diseases. In addition to tinnitus, patients of this type often have other symptoms of corresponding diseases, such as cardiovascular disease, hypertension, diabetes, brain trauma, etc. Specifically speaking, the causes of tinnitus can be summarized as follows:

① Mainly ear diseases, such as external ear diseases: external otitis, cerumen embolism, foreign bodies in the external ear, acute and chronic inflammation of the middle ear, tympanic membrane perforation, otosclerosis and Meniere's syndrome and acoustic neuroma in the inner ear can all cause tinnitus.

②Vascular diseases can also cause tinnitus, such as jugular glomus tumor, dilation of small blood vessels in the ear, vascular malformations, hemangiomas, etc. Tinnitus from veins is mostly noisy, while tinnitus from arteries is consistent with the pulsation of the pulse.

③Some other systemic diseases can also cause tinnitus: autonomic nervous system disorder, lack of blood supply to the brain, pre-stroke, hypertension, hypotension, anemia, diabetes, and malnutrition.

④ In addition, excessive use of products that are toxic to the ears, such as gentamicin, streptomycin, or kanamycin, can also cause tinnitus and hearing loss, and tinnitus occurs earlier than hearing loss.

⑤ Excessive fatigue, lack of sleep and excessive emotional tension can also cause tinnitus.
