One of the clinical symptoms of fluctuating hearing loss Meniere’s disease manifests itself. Meniere’s disease, Meniere’s disease, also known as Meniere’s syndrome (Meniere’s syndrome, Meniere’s disease, otalgia, vertigo) Meniere39;sdisease is an accumulation of fluid in the vagus of the inner ear, manifested as episodic vertigo, fluctuating hypoacusis and tinnitus. The following are also common causes of fluctuating hearing loss: 1. Deafness Deafness is clinically classified as conductive deafness caused by lesions in the outer and middle ear; neurological deafness caused by lesions in the inner ear and the auditory nerve; and mixed deafness caused by lesions in the outer middle ear and the middle ear auditory nerve together. There are many causes of deafness, including heredity, birth injury, infection, improper drug application, immune disorders, physiological degeneration, and poisoning by certain chemicals. It is important to detect, diagnose and treat deaf patients as early as possible. For conductive deafness and mixed deafness, the cause should be investigated and treated thoroughly to improve the environment and sound transmission function in the middle ear and to restore hearing to the maximum extent. 2. Hearing impairment Hearing impairment (dysaudia) refers to the occurrence of organic or functional abnormalities in the nerve centers of the auditory system at all levels of sound transmission, sound perception and comprehensive analysis of sound, resulting in different degrees of hearing loss. It is customarily called deafness. Deafness is only called deafness if the hearing loss is severe, which means that the patient cannot hear any speech in both ears. If the hearing loss does not reach this level of severity, it is called hearing loss. Nausea and vomiting Nausea and vomiting is one of the most common clinical symptoms. Nausea is a special subjective feeling, manifested as stomach discomfort and fullness, often as a prelude to vomiting, mostly accompanied by salivation and repeated swallowing action; vomiting is a reflexive strong contraction of the stomach, through the stomach, esophagus, oral cavity, diaphragm and abdominal muscles and other parts of the synergistic action, can force the stomach contents from the stomach, esophagus through the oral cavity rapidly out of the body. Nausea and vomiting can be caused by a variety of very different diseases and pathophysiological mechanisms. The two may or may not accompany each other. 4.Pediatric labyrinth edema-ear vertigo syndrome Labyrinth edema-ear vertigo syndrome, or Ménière disease, also known as Ménière syndrome, otologic vertigo, labyrinth disease, membrane labyrinth fluid, etc., was first documented by French physician Ménière in 1861 as a triad of one-sided tinnitus-deafness-vertigo, and proposed “inner ear vertigo theory” for non-inflammatory inner ear vertigo.
