title: Unrepaired clefts in the hard palate: speech deficits at the ages of 5 and 7 years and their relationship to size of the cleft.
abstract: The purpose of the study was to investigate the relationship between the size of oronasal openings in the hard palate and speech deficits. Audiotape recordings and plaster casts were taken according to standard procedures at 5 and 7 years of age from 22 consecutive children born with complete unilateral cleft lip and palate treated at Sahlgrenska University Hospital, Göteborg, Sweden. The soft palate had been repaired before the age of 12 months, whereas the cleft in the hard palate was left unrepaired, to be closed later. Perceptual judgements of nine speech variables at 5 and 7 years of age were correlated with measures of the area of the residual cleft in the hard palate. "Retracted oral articulation" (to velar place) found in nine of the 22 children correlated significantly with the area of the cleft at the age of 5 years but not later. The establishment of this particular speech error seems to be related to the size of an oronasal opening.
