More and more parents today are realizing that when a child develops an upper respiratory infection, they need to check their little ears to find out early if their child has otitis media. I have summarized five common questions about otitis media in children. I. Is secretory otitis media in children a common disease? Yes. Although, the results of foreign evidence-based medical studies confirm that up to 96% of children have had secretory otitis media with a high recurrence rate, parents need not be overly concerned. Most acute otitis media can heal on their own, and the vast majority can be completely restored to normal with reasonable treatment, with only a very small number requiring further surgical treatment. Chronic otitis media can be caused by the lack of timely and appropriate treatment during the acute period, or by repeated attacks and delays. Parents should pay attention to the daily behavior of their children and strive for early detection, early diagnosis and early treatment. How should parents pay attention to the signs of otitis media in children? Children often show signs of dullness in listening or inattentiveness. Older children will tell their parents about a feeling of stuffiness or blockage in the ear, hearing loss, and ringing in the ear. It mostly occurs after a cold, or unknowingly. C. Why must I have a hearing test? Acoustic conductance test is the most frequently performed basic audiological diagnostic test and is an important reference for diagnosis. It is also an important basis for determining the degree of disease recovery, so doctors will often request such a test. IV. How do doctors diagnose secretory otitis media? According to the symptoms of clinical hearing loss, examination reveals such manifestations as tympanic membrane invagination, pink or yellow oil, and hair line, and audiological examination reveals B-type tympanic chamber conductivity map, the diagnosis is generally not difficult. Eustachian tube manometry should also be done to understand the open function of the eustachian tube. V. What are all those methods to treat secretory otitis media? 1.Check for allergic rhinitis and adenoid hypertrophy first, and treat accordingly to remove the disease causing secretory otitis media. 2.Improve middle ear ventilation: Use nasal spray hormone spray. Control allergic rhinitis. Aeration treatment can be carried out with the Bon Ear Appropriate Middle Ear Negative Pressure Therapy Instrument. 3.Clear middle ear fluid: If conservative treatment is not effective, tympanic membrane puncture and fluid extraction, tympanic membrane placement, etc. are required. Once the tympanic tube is placed, the tube should be removed after the function of the eustachian tube has recovered in about six months. 4.If the child cannot be cured after conservative treatment with drugs or even removal of adenoids or middle ear placement, children with poor eustachian tube function should undergo balloon dilation of the eustachian tube (BET) as early as possible to solve the problem of eustachian tube dysfunction and thus treat secretory otitis media.
