Earache in children after a cold is a very common phenomenon, and because most of them have a short-lived pain, they are often ignored by parents, while many of them are actually acute otitis media caused by a cold, which in most cases is actually a secretory otitis media rather than a purulent otitis media. However, there are some cases that go unnoticed by children and become chronic secretory otitis media. Knowing the above process, parents should keep in mind the transient ear discomfort after a cold in children and visit an otology clinic at an appropriate time in order to rule out secretory otitis media, so as to maximize timely treatment and prevent chronicity. In the treatment of pediatric secretory otitis media, medications are generally based on treating inflammation in the nasopharynx to improve the function of the eustachian tube, including improving the inflammation of the adenoids (also known as proliferators). A few children with adenoid hypertrophy causing long-term open-mouth breathing and affecting development consider removing the adenoids. In most cases adenoids do not require surgical intervention, especially for adenoidal hypertrophy of short duration. In cases where, after a reasonable and appropriate length of treatment, usually 3 months to 6 months or even 1 year of observation, there is still no sign of reversal of the secretory otitis media, such as when CT shows that the middle ear is filled with fluid without any gas, consider middle ear placement, which means making a small incision in the tympanic membrane and placing a small round tube so that gas will enter the middle ear and lower the negative pressure in the middle ear, thus improving the eustachian tube After a few months of observation (usually about 6 months), the tube can be removed and the eardrum will basically heal on its own. Only a very small number of children will develop secretory otitis media again after removal of the tubes, requiring repeated placement of the tubes, and this will eventually end in permanent perforation of the eardrum, which may be treated with balloon dilation of the eustachian tube. In the case of secretory otitis media, most of the hearing loss is conductive, and as the disease disappears, hearing returns to normal without any residual effects. Most of the cases treated with tube placement will also return to normal, but in the case of repeated tube placement, late disease prolongation may lead to middle ear epithelial proliferative disease. In conclusion, otitis media is not a terrible disease. It may recur in children, but the ultimate prognosis is good in most cases with reasonable regular follow-up. Parents need not be overly concerned, leading to unnecessary over-intervention.
