Patient's question:
My daughter is 4 years and 4 months old. She said her ears hurt, so we took her to the doctor for a check-up. The doctor diagnosed her with otitis media. After treatment, her ears stopped hurting, but the doctor said there was still fluid inside. Just two months later, it came back. I know that frequent episodes of otitis media can lead to hearing problems.Doctor's answer:
Mechanism of Secretory Otitis MediaThe main causative factor is adenoid hypertrophy. Additionally, eustachian tube dysfunction, allergies, and immune factors also play a role. Enlarged and hypertrophic adenoids can compress and obstruct the pharyngeal orifice of the eustachian tube, leading to drainage obstruction of the eustachian tube and middle ear cavity. Hypertrophic adenoids serve as a chronic local infection focus, causing retrograde infection of the eustachian tube. Obstruction of nasal and nasopharyngeal ventilation can lead to retrograde flow of the eustachian tube, disrupting its physiological function. Clinically, the high incidence age of secretory otitis media aligns with the age of lymphoid tissue hyperplasia in the nasopharynx of children, demonstrating the significant impact of adenoid hypertrophy on pediatric secretory otitis media.
For adenoid hypertrophy, the current best treatment is surgical removal, which generally yields good results, and surgery is typically recommended for children aged 4 and above. However, if the child develops "adenoid facies," recovery becomes much more difficult, which would be very regrettable. Whether surgery is indicated should be determined in consultation with an otolaryngologist specializing in the nasopharynx. Under general anesthesia, adenoid removal generally does not leave sequelae. For postoperative care, please refer to my previous Q&A for detailed instructions, which I hope will be helpful to you.
