The correlation between adenoid hypertrophy and secretory otitis media in children.

Objective To explore the correlation between adenoid hypertrophy and secretory otitis media. Methods The cases of adenoid hypertrophy were screened and selected by nasopharyngeal lateral X ray. We chose 58 normal children after the clinical examination as control group. In accordance with the degree of adenoid hypertrophy,they were divided into three groups:the normal group,middle-grade and high-grade groups of adenoid hypertrophy with the association between the degree of adenoidal hypertrophy and the incidence rate of secretory otitis media analyzed. Results There was no difference in the incidence rate of secretory otitis media between the normal and middle-grade groups. The incidence rates of secretory otitis media were significantly different between the normal and high-grade groups(P 0.01). Conclusion The incidence of secvetory otitis media and the degree of adenoid hypertrophy showed positive correlation. The greater is the size of adenoids,the severer is the degree of obstruction of the nasopharyngeal cavity and the higher is the incidence of secretory otitis media.
