The treatment of secretory otitis media is mainly to improve middle ear ventilation, remove middle ear effusion and cause treatment. To improve middle ear ventilation, first of all, it is advisable to keep the nasal cavity and pharyngeal opening of eustachian tube unobstructed. Ephedrine can be dripped into the nose, or ephedrine and cortisone can be sprayed into the nasopharynx. After the acute upper respiratory tract inflammation is controlled, the eustachian tube can be inflated by pinching the nose, blowing with Bohr ball or blowing with catheter. Or inject steroid hormone liquid such as prednisolone into the pharyngeal orifice of eustachian tube through catheter to relieve local edema. I wish the child a speedy recovery.

Otitis media, commonly known as "rotten ears", is inflammation of tympanic membrane mucosa. Inflammation occurs when bacteria enter the tympanic cavity, and the resistance is weakened or the bacterial toxin is enhanced, which is manifested as earache (aggravated at night), fever, aversion to cold, bitter taste, red or yellow urine, constipation and hearing loss. For example, if the tympanic membrane is perforated, pus will flow out of the ear, and the pain will be relieved, which often coexists with chronic mastoiditis. Incomplete treatment in the acute stage will turn into chronic otitis media, and with the change of constitution and climate, pus will often flow in the ear for many years.
