Objetivo: Estudar a habilidade motora do lábio e da língua em indivíduos com fissura isolada de palato e em indivíduos com fissura de palato associada à fissura labial, comparativamente a indivíduos sem fissura labiopalatina. Método: Participaram do estudo 88 crianças de ambos os sexos, com idade entre 9 e 12 anos, distribuídas em três grupos: 28 crianças com fissura pós-forame incisivo operada, 30 com fissura transforame incisivo unilateral operada e 30 sem fissura labiopalatina ou má oclusão que constituiu o grupo controle. Avaliou-se a mobilidade dos lábios e da língua, a partir de imagens gravadas de 12 movimentos dos lábios e 17 da língua; a atividade eletromiográfica do lábio superior obtida com eletrodos bipolares de superfície durante a protrusão dos lábios, considerada atividade máxima, e na produção da silaba pa, calculando-se a porcentagem da máxima atividade labial utilizada na emissão da sílaba; além do teste da DDC a partir da repetição das sílabas pa, ta, ca e da sequência pa-ta-ca, analisando-se para as sílabas os parâmetros fornecidos pelo programa Motor Speech Profile Advanced (MSP) da KayPENTAXTM, e para a sequência pataca a contagem do número de emissões por segundo. Resultados: Quanto à mobilidade, verificou-se menor escore para os lábios no grupo controle comparado aos dois grupos fissura e menor escore para a língua no grupo controle que no grupo com fissura transforame. Em relação à atividade eletromiográfica, não houve diferença entre os grupos para a protrusão labial, mas a porcentagem da máxima atividade utilizada na emissão da sílaba foi maior no grupo pós-forame comparado aos grupos controle e transforame. Para a DDC, obteve-se maior número de emissões por segundo e menor tempo médio entre as emissões da sílaba ca no grupo controle comparado ao grupo transforame e maior número de emissões por segundo da sequencia pataca no grupo controle que no grupo pós-forame. Conclusão: Na amostra estudada, a mobilidade labial foi reduzida nos grupos com fissura e a mobilidade lingual foi reduzida no grupo transforame comparado ao grupo sem fissura; maior porcentagem da atividade máxima labial para produzir a silaba pa foi utilizada na fissura pós-forame; a velocidade de emissão da sílaba ca foi menor na fissura transforame, assim como na fissura pós-forame houve menos emissões da sequência pa-ta-ca que no grupo sem fissura. / Objective: To investigate the tongue and lips motor ability in subjects with isolated cleft palate as well as in subjects with cleft palate associated with cleft lip compared to subjects without cleft lip and palate. Methods: Eighty eight children with both genders, between the ages of 9 and 12 years old, took part in this investigation. Being distributed in three groups: 28 children with repaired isolated cleft palate, 30 with repaired unilateral cleft lip and palate and the control group which consisted of 30 children without cleft lip and palate or malocclusion. This investigation assessed the lips and tongue mobility through recorded images of 12 lips movements and 17 tongue movements; the electromyographic activity of the upper lip, which was obtained through bipolar surface electrodes during the protrusion of the lips, considered as the maximal activity, and during the production of the syllable \"pa\", by calculating the percentage of the lips maximal activity used in the syllable emission and the DDK test through the repetition of the syllables pa, ta, ca and the sequence pa-ta-ca, by analyzing the syllables through the parameters provided by the program Motor Speech Profile Advanced (MSP) of the KayPENTAXTM, and the sequence pataca by counting the number of emissions per second. Results: Regarding the mobility, it was verified a lower score to the lips in the control group than in the other two groups with cleft, and a lower score to the tongue in the control group than in the group with unilateral cleft lip and palate. Regarding the electromyographic activity, there was no difference between the groups as to the protusion of the lips, but the percentage of the maximal activity used in the syllable emissions was greater in the group with isolated cleft palate than in the groups control and unilateral cleft lip and palate. As to the DDK, it was verified a greater number of emissions per second and a lower mean time between the emissions of the syllable ca in the control group compared to the group with unilateral cleft lip and palate and a greater number of emissions per second of the sequence pataca in the control group than in the group with with isolated cleft palate. Conclusion: In the investigated sample, the mobility of the lips was decreased in the groups with cleft and the mobility of the toungue was decreased in the group with unilateral cleft lip and palate compared to the group without cleft; an increased percentage of the maximal activity to produce the syllable pa was used in the group with the isolated cleft palate; the rate of the emission of the syllable ca was lower in the unilateral cleft lip and palate, as in the group with isolated cleft there were lower emissions of the sequence pa-ta-ca than in the group without cleft.

Conclusion: There was a good level of agreement between the perceptual tests and the videofluoroscopy judgments for the consistent velopharyngeal closure and non velopharyngeal closure conditions, but not for the inconsistent velopharyngeal closure.

Objetivo: Investigar a efetividade da cirurgia de retalho faríngeo (RF) e da palatoplastia secundária com veloplastia intravelar (VI) na correção da insuficiência velofaríngea (IVF) e comparar os resultados pós-cirúrgicos de hipernasalidade, hiponasalidade, nasalância e grau de fechamento velofaríngeo entre as duas cirurgias. Material e Métodos: Estudo conduzido no Laboratório de Fisiologia do HRAC-USP, em 78 indivíduos, de ambos os sexos, com idade entre 6 e 52 anos (21±10 anos, em média), com fissura de palato±lábio, já submetidos à correção cirúrgica da IVF há 14 meses, em média, sendo 40 pacientes com RF e 38 com VI. A hipernasalidade e a hiponasalidade foram classificadas perceptivamente por três fonoaudiólogas a partir de amostra de fala gravada. A nasalância foi determinada por meio da nasometria e o fechamento velofaríngeo foi aferido a partir da medida da área do orifício velofaríngeo obtida por meio da avaliação aerodinâmica. Diferenças entre as duas técnicas foram consideradas estatisticamente significantes ao nível de 5%. Resultados: Verificou-se ausência de hipernasalidade em 35% e 70% dos casos e, presença de hiponasalidade em 10% e 25% dos pacientes com RF, de acordo com a avaliação perceptiva da fala e a nasometria, respectivamente e, fechamento velofaríngeo adequado em 80% dos casos, de acordo com a avaliação aerodinâmica. Nos pacientes com VI, ausência de hipernasalidade foi verificada em 29% e 34% e hiponasalidade foi detectada em 3% dos casos, respectivamente na avaliação perceptiva da fala e na nasometria e, fechamento velofaríngeo adequado foi observado em 50% dos pacientes. Conclusão: O retalho faríngeo foi mais eficiente que a palatoplastia secundária com veloplastia intravelar na eliminação dos sintomas da IVF. / Objective: To investigate the effectiveness of pharyngeal flap surgery (PFS) and the secondary palatoplasty with intravelar veloplasty (IV) for velopharyngeal insufficiency management (VPI) as well as to compare the postoperative outcome of hypernasality, hyponasality, nasalance and velopharyngeal closure between the two surgeries. Methods: Study conducted at the Laboratory of Physiology, HRAC-USP, on 78 individuals of both genders, aged between 6 and 52 years (21±10 years, on average), with cleft palate±lip , underwent surgical management of IVF for 14 months on average, 40 patients with RF and 38 with IV. Hypernasality and hyponasality were perceptually rated by three speech pathologists using recorded speech samples. Nasalance was determined by means of nasometry and velopharyngeal closure was assessed by means of velopharyngeal orifice area measurement provided by pressure-flow studies. Differences between the two techniques were considered statistically significant at 5%. Results: Absence of hypernasality was observed in 35% and 70% of the cases, and presence of hyponasality in 10% and 25% of the patients submitted to RF, according to the perceptual speech assessment and nasometry, respectively, and adequate velopharyngeal closure was observed in 80% of the cases, according to the aerodynamic evaluation. Absence of hypernasality in patients submitted to VI, was observed in 29% and 34%, and hyponasality was detected in 3% of the cases, respectively according to the perceptual speech assessment and nasometry, and adequate velopharyngeal closure was observed in 50% of these patients. Conclusion: The pharyngeal flap surgery was more efficient than the secondary palatoplasty with intravelar veloplasty regarding the elimination of IVF symptoms.

Children with cleft lip and/or palate show early delays in speech and vocabulary development that may have an impact on later communication and social development. While delays in the complexity of babbling may put children at risk for later delays in speech and language development, there is considerable variability in development. This study focused on the rate of children's communication acts, canonical vocalizations, and word use as they made the transition from the pre-linguistic to linguistic development. The study included 15 children with non-syndromic cleft lip and/or palatewho were seen at three time points between 17–34 months age. Communication rates were calculated from parent–child language samples collected during play activities. Assignment to linguistic stages was based on the children's expressive vocabulary, as reported on the MacArthur Communicative Development Inventory: Words and Sentences. From the pre-linguistic to linguistic level, the children's average rate per minute of: communicative acts overall increased significantly from 1.49 to 3.07 per minute; canonical vocalizations from 0.21 to 0.90 per minute; and word usefrom 0.16 to 3.61 per minute. Rates of communicative acts were associated with later word use. It appears that children with clefts rely on non-verbal communicative acts when verbal development is delayed.

Studies of early communicative development have shown a relationship between rates of communicative acts (CA) and the acquisition of words for typically developing children. Rates of CA provide a measure that predicts vocabulary growth. For children with cleft lip and/or palate, early vocabulary delays are common. Examination of rates of CA may provide a means for predicting which children show readiness for vocabulary expansion. The purpose of this study was to examine children’s rates of CA, canonical vocalizations (CV), and words during the transition from prelinguistic to linguistic development. This retrospective study included 15 participants from northeast Tennessee that were drawn from a previous longitudinal study of nonsyndromic children with cleft lip and/or palate. There were nine females and six males; nine of the participants had cleft lip and palate, while the remaining six participants had cleft palate only. Through video recordings, children were evaluated at 18, 24, and 30 months of age, during which time they transitioned from the prelinguistic level (< 10 words on CDI) to the linguistic level (> 10). Data was recorded on the number of CA [e.g., protodeclaratives (PD) and protoimperatives (PI) to determine the purpose of communication], CV, and words the child produced at each age. The data was then converted to a rate per minute ratio. The results show that from the prelinguistic to the linguistic level, the children’s average rate of CA overall increased from 1.94 to 3.08; PD from 18.86 to 19.45; words from 0.46 to 2.66 and both CV and PI decreased from 0.39 to 0.36 and 0.21 to 0.00 respectively. Results indicate that when compared to typically developing children, children with cleft lip and/or palate demonstrated delays when transitioning from prelinguistic to the linguistic level in rates of CA, CV, and words. This study did not show a significant correlation between CA at the prelinguistic level and word use at the linguistic level. When compared to the study of typically developing children conducted by Proctor-Williams, Dixon, Brown, Ringley, Barber, and Light-Newell (2007), the participants in this study demonstrated a delayed progression in the rate of CA, CV and word acquisition. Scores for PI and PD were not found to be statistically different across age groups for children with cleft lip and/or palate. Measurement of rates of CA at the prelinguistic level could assist clinicians in better assessing early communicative development in children with cleft lip and/or palate beyond traditional measures of vocalization. While this study did not find a significant difference between prelinguistic CA and linguistic CDI, CV, and words, a study with more participants is necessary to identify potential predictive relationships. This study identified differences in rates of CA, CV, and words, which suggest that early delays are not restricted to developmental parameters associated with sound production. Future studies should also incorporate testing at closer age intervals to more specifically determine their development and provide a better indication of rates of CA and CV per minute.
