Some idiopathic deafness can be cured, but some idiopathic deafness is not treated well. Idiopathic deafness, also known as sudden deafness, refers to a sudden, unexplained sensorineural hearing loss that is not a separate disorder. Sudden deafness usually occurs within minutes, hours or a day when the patient’s hearing falls to its lowest point (in a few cases, on the third day after onset), with a hearing loss of >20 dBHL in at least two adjacent frequencies. Its etiology is unknown; mood swings, late nights, and exertion are triggers, and the hearing loss is accompanied or sequentially accompanied by symptoms such as tinnitus or vertigo and periaural sensory disturbances. Idiopathic deafness has a certain tendency of self-healing. Most of the idiopathic deafness can be restored to normal after active treatment, but there are still some idiopathic deafness even after timely and standardized treatment without any improvement in hearing loss symptoms, and ultimately choose to wear a hearing aid to improve hearing.
