The cloudy tympanic membrane has the possibility of recovering on its own, provided that no new organisms grow in the posterior nostril and nasopharynx, and that the opening of the Eustachian tube must be well open, so that the fluid will be drained outward through the opening of the Eustachian tube on its own. If the patient’s Eustachian tube is blocked due to inflammation, tumors or other factors, it is often necessary to treat the primary disease. For example, if the eustachian tube becomes cloudy after a cold or during an attack of rhinitis or sinusitis, it is best to take anti-inflammatory medications orally and medications to promote outward secretion of the fluid, along with nasal hormone sprays, in order to recover more quickly from the disease. Clinically used anti-inflammatory drugs are generally amoxicillin capsules, cefdinir, cefaclor, etc., need to clarify the history of allergies before using the drug; commonly used mucus drainage agent is eucalyptus pinocin enteric soft capsule, oleander drops, etc., to promote the cilia swing, can accelerate the effusion of the fluid inside the middle ear cavity outward; commonly used nasal hormone sprays are endosulfan, coxsulan, budesonide nasal spray, trichostatin nasal spray and so on. In life, patients need to exercise more, enhance resistance, avoid repeated colds, for chronic rhinitis, sinusitis patients should actively control the symptoms, pay attention to the way of blowing the nose. If there are new organisms growing in the posterior nostril and nasopharynx, they should go to the regular hospital for consultation, and if necessary, take the pathology examination to make a clear diagnosis, and according to the pathology results, choose the appropriate treatment, such as surgery, radiotherapy and so on.
