What is the cause of tinnitus and brain ringing?

Vascular diseases most often cause pulsating tinnitus. For example, the arterial blood vessels near the temporal part of the ear may transmit the sound of blood turbulence, and the carotid system is also a common sound source. Patients with benign intracranial hypertension, S-shaped sinus diverticulum or obvious jugular bulb can hear venous hum.

Tinnitus caused by hearing loss

Hearing loss related to aging, that is, presbycusis, usually begins at about 60 years old. Long-term exposure to high-decibel noise (46 to 50 decibels is appropriate), or long-term exposure to noise environment will also damage people's hearing system, leading to hearing loss, such as large entertainment places (slow-rocking bars, KTV, etc. ).

Severe head or neck trauma

It can damage nerves, blood flow and muscles, thus causing tinnitus. This tinnitus symptom is often more serious. Temporomandibular joint disorder Temporomandibular joint connects mandible and skull, which is located in front of ear and controls the action of opening mouth, closing mouth or chewing. The injury of muscles, ligaments and articular cartilage of temporomandibular joint will lead to tinnitus symptoms, because it is adjacent to the auditory system and shares some ligaments and nerves with the middle ear. Patients with tinnitus may also feel mandibular pain or limited mandibular movement; When chewing or talking, there is a joint rubbing sound. Nasal congestion caused by a severe cold, flu or sinus infection can produce abnormal pressure in the middle ear and cause tinnitus. In diving, diving, etc., acute barotrauma caused by drastic and rapid changes in water pressure may also damage the middle and inner ears and cause tinnitus.

These diseases are common diseases that cause tinnitus: endocrine diseases: hyperthyroidism, hypothyroidism and diabetes. Cardiovascular diseases: hypertension, atherosclerosis. Mental illness: depression, anxiety, catatonia. Tumor: acoustic neuroma. What are the inducing factors of tinnitus? Some people will aggravate tinnitus symptoms after smoking, drinking, drinking caffeinated drinks, eating certain foods, or under excessive stress and fatigue. The specific reasons are not completely clear.
