Articulation and Phonology in Children With Unilateral Cleft Lip and Palate

A cleft palate may influence important functions such as eating, function of the ear/hearing, speech, occlusion, and in addition social skills and acceptability related to appearance. Surgical treatment is aiming to minimize the impact of the cleft on these functions. Nevertheless there is often a need of orthodontic treatment, and if the palate is involved, speech therapy and speech improving secondary surgery. The incidence of otitis media with effusion, and related hearing problems, is high among the children. The outcome is affected by type of cleft as well as surgical method, although not yet fully clarified. Some consider the growth of the mid-face to be better if primary surgery of the hard palate is delayed, while speech development is considered to benefit from primary palate surgery performed as early as possible. Yet we don´t know which surgical method is the best. In most parts of the world and at three of six treatment centers in Sweden the palate is closed in one stage between 12 and 18 months of age. At the three other Swedish centers the cleft in the soft palate is closed at 4-6 months, and the cleft in the hard palate is repaired at 2-3 years of age.

Video-recordings of the children at 3 and 5 years of age will be used for evaluation. The speech material at 3 years of age consists of spontaneous speech and word naming. At 5 years sentence repetition and a re-telling task is added. Blindly transcription of the material after randomization, according to the transcription used for cleft palate speech in Sweden based on the IPA and ExtIPA conventions will be performed. About 30% of the material, randomly selected, will be re-transcribed and about 30% will be transcribed by an additional listener independently, for calculation of reliability. The results will be compared between groups regarding articulatory deviancies and phonological processes, and will be statistically analyzed. Impact of ear problems, hearing and speech therapy will be assessed.
