When tinnitus occurs, it is important to seek medical attention to identify the cause and follow the doctor’s instructions. Tinnitus can be caused by a variety of factors, including perforated eardrums, pulsatile tinnitus, or foreign bodies in the external auditory canal. Depending on the cause of the tinnitus, the treatment may include surgery or removal of the foreign body. 1. Tympanic membrane perforation: Tympanic membrane perforation is usually caused by trauma or inflammation in the ear, etc. Patients may experience obvious pain, hearing loss, tinnitus, etc. If the tinnitus is caused by tympanic membrane perforation, we should proactively prevent the ear from infection, and perform tympanic membrane repair after the ear is dry to alleviate the symptom of stuffy ear. 2. Vascular tinnitus: Vascular tinnitus can be caused by malformation or lesions of blood vessels in the ear. Patients can hear the sound of continuous blood flow, which causes tinnitus with heart rate. Tinnitus can be treated by reconstructing and reinforcing the exposed blood vessel walls through surgery. 3. Foreign bodies in the external auditory canal: The presence of foreign bodies in the ear may also cause tinnitus in the left ear, such as earwax and insect carcasses. These foreign bodies may strike the eardrum and produce tinnitus symptoms. The tinnitus often goes away when the foreign body is removed from the ear. Other conditions may also cause tinnitus, so patients should go to the hospital in time for an examination to determine the cause of the condition and then proceed accordingly under the guidance of the doctor.
