Abstract
Speech, velopharyngeal function, and oronasal fistula of 88 patients with cleft palate, who received palatal surgery when about 1,4-5, and 7-11 years old, were examined, and the results were as follows:
1) Normal speech was obtained in 68.2% of the patients when 4-5 years old.
2) Most of the patients with normal speech showed adequate velopharyngeal clos ure function without oronasal fistula.
3) Incidence and causes of misarticulation varied with age at evaluation.
It was suggested that velopharyngeal function and oronasal fist ula are the most responsible factors for articulation of patients following cleft palate Surgery.
