Tinnitus is a common clinical symptom, a spontaneous intrinsic noise, which is commonly known as hearing a sound in one’s ear that one should not hear or feeling a sound when there should be no sound at all. The performance varies greatly: some occur alone, some in conjunction with deafness; some are screaming in one ear, some in both ears; some ringing in the ear, some can’t point to the direction, as if the whole brain chirps (also called cranial tinnitus); some tinnitus is intermittent, some screaming day and night. Patients often feel that there are monotonous sounds such as hissing, bells, whistles, whistles, motors, crickets or cicadas in their ears or cranium, but there is no corresponding sound source in the surrounding environment, which often disturbs patients and affects their lives. Light tinnitus is felt only when one is quiet and attentive; heavy tinnitus is noisy and disturbing whether one is resting or working. Since tinnitus is caused by lesions of the auditory analyzer, auditory end organs and auditory nerve, 85% to 90% of the auditory function is affected and hearing loss occurs at the same time as tinnitus, and even if the auditory function is not temporarily damaged, hearing damage will usually occur in the future. There are various reasons for tinnitus, but the first reaction is “kidney deficiency”. In fact, this view is debatable, tinnitus has both local and systemic factors, and clinically the former is the majority, for example, for unilateral tinnitus, if it is said to be kidney deficiency, then whether it is ipsilateral or contralateral “kidney deficiency”. Even from the perspective of Chinese medicine, tinnitus has both deficiency and actual symptoms, and among the deficiency symptoms, “kidney deficiency” is only one of the more common types. Therefore, the formula of “tinnitus = deficiency = kidney deficiency” is not correct, and this is the reason why many tinnitus patients are not treated according to kidney deficiency. The local factors of tinnitus come from the outer ear, middle ear and internal 3 parts: ① Diseases of the outer ear: cerumen embolism in the outer ear canal, foreign body in the outer ear, inflammation and swelling, which block the ear canal and can cause tinnitus. ② Diseases of the middle ear: Tympanic membrane entrapment and tympanic membrane perforation and eustachian tube blockage, various types of acute and chronic otitis media, tympanic chamber effusion, otosclerosis, etc. can also cause tinnitus due to lesions in the sound transmission mechanism. Inner ear diseases: vagus disease, drug poisoning, Meniere’s disease, sudden deafness, and auditory neuroma can all cause tinnitus. It is important to note that for some tumors, tinnitus is also an early symptom that cannot be ignored and is often one of the main reasons why patients seek medical attention. In nasopharyngeal carcinoma, tinnitus is caused by the combination of infection and edema in the nasopharynx, which blocks the opening of the eustachian tube in the lateral wall of the nasopharynx. Therefore, when persistent tinnitus of unknown origin occurs, one should go to the ENT department of the hospital for examination in time to make a clear diagnosis, exclude the tumor and treat it in time. On the other hand, after radiotherapy of nasopharyngeal cancer, the nasopharynx shows chronic inflammatory changes and the secretions block the eustachian tube mouth, which will also produce tinnitus. With the repair of diseased tissues, tinnitus will disappear gradually.
