You should not smoke because smoking can affect the cilia of the mucous membrane in the eustachian tube, which is not conducive to the removal of bacteria and fluid from the tympanic chamber. Otitis media is mostly caused by upper respiratory tract infections, and the eustachian tube can cause congestion and swelling during upper respiratory tract infections, which is not conducive to the removal of fluid from the tympanic chamber. Therefore, for the treatment of otitis media, in addition to local treatment of the ear, such as 3% hydrogen peroxide to clean up the pus in the external ear canal, levofloxacin ear drops, etc., usually the nasal cavity also requires 1% furosemide nasal drops to reduce the congestion and swelling of the eustachian tube, which facilitates the decreasing of inflammation, and if the inflammation is heavy, additional antibiotic treatment, such as amoxicillin clavulanic acid potassium, azithromycin, etc., is necessary. The diet should be light and avoid spicy and stimulating foods.
