Intravelar veloplasty in cleft lip, alveolus and palate and outcome of speech and language acquisition: a prospective study

Abstract

Background: Speech and language acquisition are major, important criteria in the treatment outcomes of cleft lip and palate patients. A generally accepted and definitive treatment protocol regarding surgical techniques and the time schedule does not yet exist. In the world literature, there are reports of velo-pharyngeal insufficiency rates between 7 and 30%. Purpose: In a prospective study, all children aged 3 1 2 months with cleft lip, alveolus and palate, or cleft palate only, underwent an intravelar veloplasty. Follow-up monitoring consisted of frequent clinical linguistic checks and supervision of language development without a planned intention of articulation therapy before the age of about 5 years. Results: Three hundred and ninety-seven children with non-syndromic clefts were included in this study, the youngest being 8-year old. Sixty children (15%) showed deviations in language and speech acquisition. From these, 56 (14%) had received articulation therapy after the 5th birthday. From these 56 children, 45 had overcome their problems with speech therapy alone whereas 11 (3%) needed a velo-pharyngeoplasty. Discussion: Although these results are much better than those reported in other cohorts, some children still have velo-pharyngeal incompetence for no apparent reason. One possible explanation might be surgical, since on occasions, the intravelar muscle bundle is divided into two parts and the palato-pharyngeal part runs isolated more laterally and can be missed during reconstruction and retropositioning.
