Objective : To estimate the prevalence of speech, language, and hearing disorders in patients with cleft palate with or without
cleft lip.
Material and Method: All data were retrieved from 384 medical records, transferred to case record forms and analyzed.
Results : The oronasal fistula rate was 15.25% (95% confidence interval: CI 11.49-19.02). The overall rates of delayed
language development, articulation disorders, resonance disorders, voice disorders, and hearing disorders were 16.33%
(95% CI = 12.65-20.69), 88.56% (84.47-92.65), 43.26% (95% CI = 36.58-49.93), 19.13% (95% CI = 14.26-24.82), and
79.49% (95% CI = 74.28-84.70), respectively.
Conclusion : For speech and hearing, rates of abnormality were very high compared with those reported in the previous
studies. Treatment protocols should receive more attention and intervention.
