Effect of climatic elements on the frequency of secretory otitis media

A relationship between the number of children hospitalized for secretory otitis media and climatic elements was observed during a 10-year period (1981-1990). The highest correlation was obtained between the number of secretory otitis media cases and the number of sunny hours in a month, followed by that between the number of secretory otitis media cases and the mean monthly temperature and relative air humidity. The largest number of children were hospitalized for secretory otitis media toward the end of winter, and the lowest toward the end of summer (in August and September).
