Summary- Basic aim of the study was to investigate the incidence, prevalence, disease pattern
and the etiology of the non-syndromic congenital deafness in a selected population from
different areas and schools for special education of Faisalabad District, Pakistan. An epidem-
iological study was carried out through a questionnaire including different standard parameters
like surname, parental marriage age, parental relationship of marriage, their family history
including information about number of offspring, sex, birth order, number of normal and diseased
individuals and age of onset. Information about economic status and educational qualification of
parents, their locality, food habits and paternal smoking or non-smoking habits were also
recorded. In a total of 436 deaf cases, 55.0% were males and 44.95% were females while 22
families were selected for pedigree analysis. Urban population (79.58%) was affected more than
rural population (20.41%). Mean maternal and paternal marriage age was 20.63 ± 0.163 and
24.989 ± 0.217, respectively with smaller (0-4 years) marriage age difference.
