The absorption of fluid in the tympanic cavity caused by secretory otitis media varies from person to person. If proper medication is administered, most people absorb the fluid in about 10-14 days; some people absorb it more slowly, and it can take up to 1-3 months. In general, non-surgical treatment is needed for 3 months, and if the effusion is not absorbed particularly well, surgical treatment can be considered again. Non-surgical treatment mainly involves the application of sensitive antibiotics during the acute period, which can keep the nasal cavity as well as the eustachian tube open. Furosemide nasal drops or nasal sprays containing hormones can be applied to keep the nasal cavity open. Oral mucosal pro-discharge agents can be used to facilitate the drainage of tympanic fluid in the eustachian tube and reduce the pressure of the opening of the eustachian tube, such as standard myrtle oil or cherno. Glucocorticoid drugs can be applied orally, and then pharyngeal tube blowing, the common method is the pinch nasal puff method. If the absorption of fluid is not particularly obvious after 3 months of conservative treatment, surgical treatment can be considered, which is mostly performed under local or general anesthesia, with tympanic membrane aspiration, tympanotomy and drainage or tympanic chamber placement.
