Introduction: Childhood deafness is a multifaceted disability which affects a child’s ability to hear and delays the speech development and language learning skill. Thus results in cognitive impairments in these children including lower IQ scores, slower
information processing skills and poorer literacy skills.
Aim of the Study: To find the incidence and pattern of deafness in children with non and delayed development of speech and
to look for the risk factors associated with this.
Study Type: Retrospective, observational and analytical.
Methods and Discussion: 5504 deaf children of 0 – 12 years attended OPD of Department of ENT Dr. B.C. ROY from June,
2014 – June, 2019 .We have examined,taken detailed history, done audiological tests and assessed after dividing the children
in three age groups. Children were subdivided according to the severity of deafness and relation of each kind of deafness with
non and delayed development of speech were assessed. Associated risk factors were also looked for at each stage of study.
Results: Highest number (3328) of deaf children were found in 0-3 years of age. 1502 deaf children were found in 3-7 years
age group and 674 deaf children were found in 7-12 years age group. Speech and language development was significantly not
developed in patients with profound and severe deaf children.
Conclusion: Highest number of deaf children were found in 0-3 years of age group. Among the major risk factors that were
identified during the study in this group were prematurity, LBW, HIE, neonatal jaundice and consanguineous marriage . While
in 3-7 years and 7-12 years age groups , otitis media was seen to cause hearing loss more than the other etiologies.
