Otitis media is a common childhood disease that is gradually gaining attention from parents because it can cause hearing loss in children and affect their learning and life. Due to the young age of children, they are often unable to correctly or actively report hearing loss and other discomforts, thus delaying treatment. How can we detect otitis media in children as early as possible? We know that when a child has otitis media, he or she will often experience ear pain, sometimes severe and often crying, or a mild tingling sensation that is paroxysmal and does not last long, making it difficult to detect. Some children may experience ringing in the ears or a feeling of ear blockage, as if something is blocking the ear. In severe cases, hearing loss is often noticeable, as evidenced by the habit of turning up the sound when watching TV, calling out names that are often not heard, lack of concentration, and a decline in academic performance. At this point, careful parents should take their children to the hospital for timely diagnosis and treatment to avoid further aggravation of the child’s condition.
