Cleft Lip and Palate Patients Prior to Delayed Closure of the Hard Palate: Evaluation of Maxillary Morphology and the Effect of Early Stimulation of Pre-School Speech

Abstract

Speech and maxillary development were analysed in two groups of patients with unilateral cleft lip and palate; both groups had early jaw orthopaedic treatment and a surgical regimen that included two-stage lip surgery (mean ages of 2 and 19 months) and soft palate repair (8 months). Closure of the hard palate was postponed until the children were 8 to 10 years of age. The first group comprised 10 consecutive patients who were analysed at 5 and 7 years of age, and the second group seven patients who were studied at the age of 5. Both groups were thus investigated before the repair of the cleft in the hard palate. In addition to surgical and jaw orthopaedic treatment, the second group of patients received early stimulation of lip and tongue tip movements. Our results indicated that hypernasality was less a problem than was retracted palatal or velar articulation of dental consonants. These deviations tended to be reduced, however, after early stimulation. There seemed to be no clear association between the size of the residual cleft in the hard palate and the extent of speech development. The average size of the residual cleft in our patients was comparatively small, and decreased further during follow up. We conclude that preschool children with unilateral cleft lip and palate may develop good speech, in spite of the residual cleft, if they use an intraoral plate and are given extra lip and tongue tip stimulation, together with early speech therapy if necessary.
