Inflammation of the Eustachian tube may resolve spontaneously in some patients, but it is still recommended that patients actively go to the hospital for targeted treatment under the guidance of the doctor. The Eustachian tube is located between the nasopharynx and the tympanic cavity, connecting the nasopharynx and the tympanic cavity. Inflammation of the Eustachian tube is usually caused by viral or bacterial infections, resulting in the Eustachian tube becoming oedematous and thus blocked, resulting in symptoms such as ear pain, tinnitus, and tightness in the ear. Inflammation of the Eustachian tube due to bacterial infection can be treated with cefuroxime, amoxicillin and other drugs under the guidance of a doctor; viral infections are commonly used in patients with ribavirin, oseltamivir, acyclovir and other antiviral drugs; in some serious cases glucocorticoids can be used to eliminate localized oedema and reduce the inflammation of the secretion, such as budesonide nasal spray, methylprednisolone tablets, and so on. It is recommended to actively go to the hospital after the disease, under the guidance of the doctor to clarify the cause of the disease, standardize the use of drugs and treatment.
