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.

Anatomy of the Larynx
The larynx consists of various components, including cartilage, muscles, and vocal cords. Its structure includes three large unpaired cartilages—the thyroid, cricoid, and epiglottis—and three smaller paired cartilages—the arytenoids,...

Palpation Findings
During a respiratory assessment, palpation can reveal several vital abnormalities:

Breath Sounds
Breath sounds are categorized into vesicular, bronchovesicular, and bronchial.
