IN THE speech clinic of the Manhattan Ear, Nose and Throat Hospital, my associates and I have had the opportunity of observing and training the speech of 43 patients afflicted with the congenital deformity of cleft palate. In all but 6 patients the cleft included the lip, and in 1 patient it even extended up to the eye. In 33 of these patients the palate had been closed by operation; 6 were seen before any surgical intervention on the palate, and 4 were wearing obturators. Their ages ranged from 3½ to 47 years. Speech tests were given to children as young as 18 months, but effective speech training cannot start before the child reaches about nursery school age. Most of the patients came to the clinic for rehabilitation training twice a week.
Congenital shortening in association with cleft palate is a deficiency which causes one of the most serious impediments
