Otitis media is a common and frequent disease in childhood. Many children may have experienced a sudden onset of ear pain, sometimes even unbearable and unbearable. The doctor quickly made a diagnosis and told the parents that the child was suffering from acute otitis media and needed to be treated quickly, otherwise there was a risk of tympanic membrane perforation and pus flow, which could affect hearing. Through the doctor’s active treatment, the child’s ear pain was quickly relieved and the condition was cured. So, why do children suffer from acute otitis media? We know that children, especially infants, have a weak body resistance and are easily exposed to cold and flu. In addition, the eustachian tube of children is shorter, flatter and wider than that of adults. If upper respiratory tract infections are not treated promptly and effectively, pathogens such as bacteria and viruses can enter the middle ear cavity through the eustachian tube, leading to the occurrence of otitis media. Another important reason for acute otitis media in infants and young children is that some mothers are accustomed to having their children lie in bed while nursing them. This position can easily cause milk to reflux and enter the middle ear cavity through the eustachian tube, causing secondary infection. Children tend to show continuous crying and fussing, often for unknown reasons, and if they are not detected in time and treated aggressively, more often than not, the eardrum is perforated and pus flows. These are the common causes and clinical manifestations of acute otitis media in children. When your child has the above-mentioned conditions, do you think your child may have acute otitis media and take him/her to the hospital?
