Secretory otitis media is the main cause of hearing impairment in pediatric patients. Due to the anatomical differences between pediatric and adult patients, the eustachian tube is short and flat and dysfunctional, which can easily become impaired and lead to middle ear fluid accumulation. Since pediatric patients cannot complain that middle ear effusion can last for a long time, it eventually leads to permanent hearing damage and poor articulation. For children with delayed speech, slurred pronunciation, louder TV viewing volume, and delayed response to calls from behind, it is important to go to the hospital promptly to see if they have secretory otitis media, and early treatment is effective. How to detect otitis media in children early? 1. When chatting with others, they always ask each other to repeat and often poke one ear forward; 2. When children watch TV with the sound turned up; 3. When parents ask them to do something, children are always slow to respond; 4. In school classes, they do not pay attention, often wander off, and their academic performance slips significantly. These are all signs of slow hearing loss, and parents should pay attention if their children show the above phenomena.
