Secretory otitis media (SOM) is primarily a disease of children which
can have deleterious effect on their medical, social, educational and
psychological welfare. It is well known that SOM is a common disease,
but exact figures about its prevalence and incidence are scarce and fr
agmentary. In this community study, we determined the point prevalence
of type B tympanogram as an indication to the prevalance of SOM. The
study population consisted of a random sample of 4214 children aged 1-
8 years. The point prevalance rates of unilateral and bilateral type B
tympanogram among the children were 5.7% and 8.1%, respectively. The
point prevalance rate per ears (a total of 8428) was 10.9%. The preval
ence was found to be related to the age, the season and to the occurra
nce of the ear and upper respiratory tract infections. No correlation
was found in relation to sex, allergy or the socio-economic condition.
The findings are discussed in the light of studies conducted elsewher
