What are the causes of secretory otitis media in children?

Secretory otitis media in children is more common in winter and spring, and this disease is also one of the important causes of hearing loss in children. In order to prevent this disease from causing excessive harm to children's health, we need to pay great attention to the disease of secretory otitis media in children, especially the cause of secretory otitis media in children. So let's take a look at what authoritative experts say about this issue:

Secretory otitis media in children is caused by various factors that lead to obstruction of the Eustachian tube, resulting in impaired ventilation function. The gas through the nasal cavity cannot be exchanged with the gas in the middle ear cavity. At the same time, the gas in the middle ear tympanic cavity is continuously absorbed, resulting in negative pressure in the tympanic cavity. The atmospheric pressure transmitted through the external auditory canal causes the tympanic membrane to retract to varying degrees, and the patient will have a feeling of stuffiness in the ears. As the blood vessels in the middle ear mucosa dilate and the permeability increases, plasma exudates to form tympanic effusion, which is mostly serous.

(1) Children's Eustachian tubes are nearly horizontal, with short lumens and wide inner diameters. Nasopharyngeal infections or secretions can easily enter the Eustachian tubes. In addition, the cartilage of the Eustachian tube has low elasticity, so it is easy to collapse and block the Eustachian drum when the tympanic cavity is under negative pressure.

(2) Common rhinitis and sinusitis in children may be caused by purulent nasal discharge flowing into the nasopharynx, which may stimulate the Eustachian tube mucosa and cause inflammation or directly block the Eustachian tube opening;

(3) Excessive enlargement of the adenoids can compress and block the pharyngeal opening of the Eustachian tube. Chronic adenoids can also cause retrograde infection of the Eustachian tube.

(4) Children have low resistance, and pathogens of respiratory tract infection can enter the middle ear through the Eustachian tube and cause infection.

What are the causes of secretory otitis media in children? The above is a detailed introduction to this issue. In addition to understanding this aspect, it is recommended that children under the age of 10 should undergo regular hearing screening to try to achieve early detection, early diagnosis and early treatment. Of course, some more serious conditions may require surgical treatment. It is recommended to go to an authoritative hospital's otolaryngology clinic for diagnosis and treatment, and listen carefully to the expert's advice for treatment.
