In our daily life, we often encounter children who often turn up the volume when watching TV or playing computer games, increase the sound of speech, become unresponsive, and often do not respond when their names are called, but respond better when the volume is raised, which may lead to “ear swelling and ear closure” (secretory otitis media). With the development of social and economic development and the implementation of family planning, the birth rate of newborns has dropped significantly since the beginning of the new century, while the time and energy spent by parents on their children has increased significantly. However, we should also note that some of the more insidious diseases are not obvious in their early stages, making them difficult to detect even for the most attentive parents, and when the symptoms of the disease become obvious, they are already in a more serious condition, causing serious effects on the child’s school life, even for life. Ear diseases in children are one of the more common types. Two of the most common types of childhood ear diseases are otitis externa and secretory otitis media caused by colds. Because otitis externa has a rapid onset, with symptoms such as ear pain and fever at the beginning, parents are able to detect it early and seek medical attention quickly, and the consequences are generally mild, so I won’t go into the details here. What really needs to be brought to the attention of parents is secretory otitis media in children, which is called ear swelling and ear closure in Chinese medicine. To understand the characteristics of otitis media in children, we need to start with the cause of the disease. First, the lumen of the eustachian tube is short, the internal diameter is wide, and the location of the tympanic opening is lower in children than in adults, so nasopharyngeal secretions and bacteria and other microorganisms can easily invade the middle ear through it. Fourthly, children have poor resistance and are prone to catching colds or infectious diseases and other complications of middle ear infections. From the above, we can see that the probability of otitis media in children is much higher than that in adults is justified. We have treated a large number of cases of acute otitis media in children who were not treated in time due to parental negligence, resulting in perforation of the tympanic membrane, affecting hearing, or even severe purulent otitis media, damaging the structure of the middle ear auditory chain and causing permanent hearing loss, or the infection site migrated and spread to the skull, causing intracranial infection and thus This can lead to life-threatening infections. The key to early detection of otitis media is the combination of clinical manifestations and specialized examination. Early symptoms usually include a history of colds, bilateral nasal blockage, hearing loss, and a feeling of stuffiness in the ear. If the child is too young to express the symptoms clearly, we can judge from some of his abnormal behaviors, such as unexplained ear scratching, head shaking, crying and restlessness, loud speech, high TV sound, slow auditory response, frequent colds, nasal congestion, open mouth breathing, snoring and loud snoring during sleep. When the above symptoms appear, together with the specialized examination of our department, such as hearing examination, electronic otoscope, acoustic conduction resistance, etc., the diagnosis can be basically confirmed. If the diagnosis of childhood secretory otitis media can be clearly established, its treatment is relatively simple. Early application of sufficient amount of non-otoxic sensitive antibiotics and mucus promoting agents, and local maintenance of nasal passages. If the middle ear secretion cannot be absorbed and discharged due to incomplete control by antibiotics, tympanotomy can be considered to drain the middle ear secretion if necessary. As mentioned above, otitis media is a common childhood ear disease with a rapid onset and relatively serious consequences, so it should first be prevented from catching a cold and treated promptly when nasal congestion and runny nose occur.
