Point prevalence of type B tympanogram in Riyadh.

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 fragmentary. In this community study, we determined the point prevalence of type B tympanogram as an indication to the prevalence of SOM. The study population consisted of a random sample of 4214 children aged 1-8 years. The point prevalence rates of unilateral and bilateral type B tympanogram among the children were 5.7% and 8.1%, respectively. The point prevalence rate per ears (a total of 8428) was 10.9%. The prevalence was found to be related to the age, the season and to the occurrance 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 elsewhere.
