Baby otitis media can have different manifestations depending on the age: 1. Infants and toddlers who are not yet able to express themselves mostly show crying, reluctance to eat, scratching their ears with their hands, patting their heads, restless sleep, etc.; 2. Children who are a little older and can express themselves mildly will say that their ears hurt, that they cannot hear well, that their ears ring, that their voices are particularly loud when they speak, etc. Or babies themselves do not have any complaining symptoms, but are found by their parents to have poor hearing and No response to hearing; 3. Symptoms of fever may occur regardless of age. When parents find that their babies have the above symptoms, they must pay attention to take their children to the hospital for examination in time. You can go to the ENT department for endoscopy to check the performance of the external ear canal and tympanic membrane, such as whether there is redness and swelling in the external ear canal, whether the tympanic membrane is perforated and congested, and whether there is purulent discharge inside the external ear canal, etc. After this diagnosis is clear, further treatment can be carried out.
