What is tinnitus and deafness?

Tinnitus can be divided into subjective tinnitus and objective tinnitus, and daily tinnitus mainly refers to subjective tinnitus. Tinnitus mostly refers to patients consciously ringing in their ears, which is a subjective feeling, and there is no corresponding sound source in the environment. Tinnitus is more serious in quiet state. The patient consciously rings in the ear and there is no corresponding sound source in the surrounding environment, which can occur on one side or both sides. Sometimes patients feel tinnitus coming from inside the skull, which can also be called cranial ringing or brain ringing. Deafness refers to different degrees of hearing loss, and the weaker hearing is called hard of hearing. Tinnitus and deafness are common symptoms of various ear diseases, and the primary disease can only be found through detailed medical history and related examination. To understand the causes of deafness and tinnitus, we must know the principle of deafness and tinnitus. Sound travels from the outer ear to the middle ear, to the inner ear, and finally to the center to produce hearing. If there is a problem anywhere in this path, hearing loss or tinnitus may occur. For example, if there is a problem with the external ear, there is a cerumen embolism in the external auditory canal, and the external auditory canal is damaged, it will lead to hearing loss. Problems in the middle ear, such as otitis media, perforation of tympanic membrane, pus in the ear, etc., will lead to hearing loss. There are problems with the inner ear, such as explosive deafness and barometric deafness in the elderly. All of the above will lead to hearing loss. Deafness and tinnitus is one of the symptoms of various ear diseases, and it can also be used as a separate disease, which can be acute or chronic, bilateral or unilateral, some persistent and some intermittent. Tinnitus tone can be high or low, which is usually serious when it is quiet, and can affect sleep, life and work when it is serious. Most patients with tinnitus are accompanied by hearing loss.
