Ménière Disease (Ménière Disease), also known as Meniere syndrome or endolymphatic hydrops, is an ear-derived vertigo disease characterized by membranous labyrinth hydrops. The characteristic manifestation is repeated episodes of rotational vertigo, fluctuating sexy Acoustic hearing loss is often accompanied by tinnitus and/or ear fullness. The etiology is unknown and may be related to a variety of factors. The basic etiology: Meniere’s disease is mainly caused by imbalance in the production and absorption of endolymph. There are many related theories. Mechanical obstruction of endolymphatic vessels and dyssorption of endolymph. Any stenosis or obstruction in the longitudinal endolymphatic flow, such as endolymphatic sac dysplasia, congenital stenosis, thickening of inflammatory fibrosis, etc., may cause mechanical endolymphatic vessels Obstruction or dyssorption of endolymph, leading to hydrops in the labyrinth, this theory has been confirmed by animal experiments. Theory of immune response In recent years, a large number of studies have confirmed that the inner ear can receive antigen stimulation and produce an immune response. Antigens that enter the human inner ear in different ways or are produced by itself can stimulate immune active cells that gather around blood vessels, endolymphatic sacs and endolymphatic vessels to produce antibodies. The inner ear is stimulated by the antigen-antibody reaction, resulting in capillary dilatation, increased permeability, body fluids penetrating the labyrinth, and hypersecretion of the stria vascularis, especially the endolymphatic sac absorption function due to the deposition of antigen-antibody complexes, which can cause membrane Lost and stagnant water. Inner ear ischemia theory. Inner ear small vasospasm and autonomic nerve dysfunction can cause microcirculation disorders in the inner ear and endolymphatic sac, causing tissue hypoxia, metabolic disorders, increased endolymph osmotic pressure, and migration of fluid in the perilymph and blood to form Membrane labyrinth water.
Everyone knows that the health problems of our various organs are closely related, so does ear vitiligo affect hearing? Many people are worried about hearing vitiligo. According to the doctor, ear vitiligo may cause hearing loss. Let’s take a look at it in detail below, and hope that patients will pay attention to this issue so as not to be adversely affected. Vitiligo is caused by the damage of melanocytes in the patient, and there is melanin in the ears. In the cochlear striate vessels of the inner ear, the cochlear cochlea, vestibular organs, and lymphatic vessels are the main distribution sites of melanin in the ear, which may cause melanin deficiency to cause ears Some parts of the ear are malfunctioning, causing hearing loss, so patients with ear vitiligo should pay special attention. Vitiligo has an impact on hearing. Studies have found that hearing and brainstem auditory responses of patients with vitiligo have found that some patients have abnormal sensorineural hearing loss. It is generally mild hearing loss or moderate hearing loss. Many patients with ear vitiligo have early symptoms of hearing loss or tinnitus, so you must pay attention to hearing protection when suffering from vitiligo. The occurrence of vitiligo may cause the cochlear dysfunction characteristically to affect the high frequency range, but it can also affect all frequency ranges, sometimes even more serious. Inner ear dysfunction usually improves within a few months of the recovery period, but hearing can continue to decrease. Therefore, patients need to pay attention to protecting hearing. Patients with vitiligo should consult a professional doctor for hearing protection. Since the function of inner ear melanocytes is not yet clear, it may play a role in protecting inner ear capillaries from vitiligo. The cells are not damaged by environmental factors such as noise and poison. Involvement of melanocytes in the inner ear may cause hearing loss. If a patient with vitiligo has ear discomfort, it is recommended to go to a professional and regular treatment, do not use drugs casually, so as to avoid the spread of the disease or hearing loss, this issue should be paid attention to.
