Objetivo: Apontar a prevalência e os achados anatomofuncionais da fissura de palato submucosa (FPSM) com indicação cirúrgica, diante do quadro sintomático, valorizando o diagnóstico e o acompanhamento da evolução do paciente em uma abordagem preventiva. Modelo: Prospectivo, amostra aleatória Local: Hospital de Reabilitação de Anomalias Craniofaciais - Universidade de São Paulo, Bauru. Pacientes: Foram avaliados 50 pacientes com FPSM, sem outros comprometimentos e 7 casos com alterações somente na úvula, na faixa etária de 20 a 46 meses, por ordem de agendamento no HRAC, no período de 1 ano. Principal resultado medido: Análise e descrição quanto à presença dos sinais clínicos específicos da FPSM e à associação com a sintomatologia. Intervenções: Avaliação fonoarticulatória e inspeção clínica. Resultados: Com relação aos sinais clínicos, observaram-se 25 (50,0%)pacientes com a tríade clássica e 25 (50,0%) com 1 ou 2 sinais clínicos. Dos 50 casos de FPSM, 10 (20,0%) mostraram-se sintomáticos e 40 (80,0%), assintomáticos. Houve associação entre a presença da tríade clássica de sinais e a sintomatologia (p= 0,011), associação dos casos sintomáticos e a presença da zona translúcida (p=0,005), alterações na úvula (p= 0,046), bem como do entalhe ósseo (p=0,029). A hipernasalidade esteve presente em 100,0% dos pacientes sintomáticos. A maior parte dos 41 pacientes com fissura pré-forame procurou atendimento nos primeiros meses de vida, devido à fissura labial e apresentou 7,3% de casos sintomáticos. Já dos 9 pacientes com FPSM isolada, 6 procuraram atendimento tardiamente, devido a queixas de fala. O grupo apresentou 77,7% de casos sintomáticos. Conclusão: Uma maior divulgação dos sinais clínicos e sintomas da FPSM entre os profissionais da área de saúde é fundamental para que o diagnóstico e a definição de conduta ocorram a tempo. / Objective: Point out the prevalence and anatomic functional findings of submucous cleft palate (SCP) with surgical indication in relation to the symptomatic aspect by giving importance to diagnosis and follow-up of patient\'s evolution in a preventive approach. Pattern: Prospective study, haphazard samples. Setting: Rehabilitation Hospital of Craniofacial Anomalies, University of São Paulo, Bauru, Brazil. Subjects: Fifty patients with submucous cleft palate (SCP) with no other complications and seven patients with alterations only in the uvula, all of them ranging in age from 1 year 8 months to 3 years 10 months. Main Outcome Measures: Assessment and description on the presence of specific clinical signs of SCP and the association with symptomatology. Interventions: Evaluation of articulatory aspects and clinical examination. Results: As for the clinical signs 25 patients (50%) were identified with the classic triad and 25 (50%) with 1 or 2 clinical signs. Out of 50 cases of SCP, 10 (20%) were symptomatic and 40 (80%) asymptomatic. There was an association between the presence of classic triad and symptomatology (p=0,011). It was also observed a correlation of symptomatic cases and presence of a translucid area (p=0,005) as well as a notch (p=0,029). Hipernasality was present in 100% of symptomatic patients. Most of 41 patients with pre foramen cleft searched for treatment in the first months of life due to cleft lip and showed 7,3% of symptomatic cases. In contrast, 6 out of 9 patients with isolated SCP searched for treament very late due to speech complaints and 77,7% of this group were symptomatic. Conclusion: It is essential to improve knowledge of clinical signs and symptoms of SCP among professionals involved in health services so that the diagnosis and definition of procedures can take place in time.

Este trabalho teve como objetivo analisar os casos com fissura de palato submucosa (FPSM) acompanhados no HRAC/USP, no período de 1984 a 2004, verificando a distribuição destes casos de acordo com a idade e conduta adotada na consulta inicial e; se a conduta inicialmente adotada manteve-se ou necessitou ser reconsiderada. Foram analisados 1.260 prontuários de pacientes FPSM, sendo excluídos 175 que apresentavam quadros sindrômicos e, portanto, a amostra final constou de 1.085 pacientes, de ambos os gêneros e procedentes das diferentes regiões do país, os quais foram distribuídos em 5 grupos etários de acordo com idade na época da consulta inicial: menores de 3 anos, de 4 a 6 anos, de 7 a 12 anos, de 13 a 17 anos e acima de 18 anos. A análise evidenciou 557 (51,33%) casos com FPSM isolada e 528 (48,67%) com FPSM associada à fissura labial, sendo os mesmos analisados de acordo com a conduta inicial adotada: acompanhamento, fonoterapia, prótese de palato ou cirurgia, respeitando-se os grupos etários definidos. Após a análise dos casos com fissura de palato submucosa acompanhados no HRAC/USP, no período de 1984 a 2004, concluiu-se que: quanto à distribuição dos casos de acordo com a conduta definida na consulta inicial, na FPSM isolada predominou a indicação para cirurgia nas idades acima de 4 anos e acompanhamento nas idades abaixo de 3 anos e, na FPSM associada à fissura labial predominou a conduta acompanhamento; Quanto à manutenção ou reconsideração da conduta inicial, dos casos indicados para acompanhamento, na FPSM isolada, a maioria dos casos alterou a conduta para cirurgia e na FPSM associada à fissura labial, a maioria manteve a conduta inicial; daqueles indicados para fonoterapia, na FPSM isolada, predominou manter a conduta inicial nas idades menores de 3 anos e de 7 a 12 anos e alterar a conduta para cirurgia nas idades de 4 a 6 anos e de 13 a 17 anos e, nos casos com FPSM associada à fissura labial, a maioria manteve a conduta inicial; dos casos indicados para prótese de palato, na FPSM isolada, a maioria dos casos entre 4 e 6 anos alterou a conduta para cirurgia, houve equilíbrio entre manter a conduta inicial e alterar para cirurgia na faixa etária de 7 a 12 anos e houve manutenção da conduta inicial na faixa etária maior de 18 anos, não ocorrendo casos com FPSM associada à fissura labial, já, dos casos indicados para cirurgia, tanto na FPSM isolada quanto na FPSM e associada à fissura labial prevaleceu à conduta inicial. / This study analyzed the patients with submucous cleft palate (SMCP) assisted at HRAC/USP during the period 1984 to 2004, checking the distribution of these cases according to age range, approach adopted at the initial consultation, and if the approach initially adopted was maintained or reconsidered. A total of 1,260 records of patients with SMCP were analyzed; 175 were excluded due to the association with syndromes, leading to a final sample of 1,085 patients, of both genders and from different regions of the country, which were distributed into 5 age groups according to the age rage upon initial consultation: younger than 3 years, 4 to 6 years, 7 to 12 years, 13 to 17 years, and older than 18 years. The analysis revealed 557 (51.33%) cases with isolated SMCP and 528 (48.67%) cases with SMCP associated with cleft lip. These cases were analyzed according to the initial approach adopted: follow-up, speech therapy, speech prosthesis, or surgery, according to the aforementioned age groups. The following could be concluded: with regard to the initial approach, for patients with isolated SMCP, there was predominance of indication for surgery at the ages above 4 years and follow-up for patients younger than 3 years, whereas in cases with SMCP associated with cleft lip there was predominance of follow-up. Concerning the maintenance or reconsideration of the initial approach, among the cases with isolated SMCP indicated for follow-up, in most cases the approach was altered to surgery, whereas the initial approach was mostly maintained for individuals with SMCP associated with cleft lip. Among individuals with isolated SMCP with indication for speech therapy, there was predominance of maintenance of the initial approach for patients younger than 3 years and aged 7 to 12 years, with maintenance of the initial approach for patients aged 4 to 6 years and 13 to 17 years, with predominance of maintenance of the initial approach for patients with SMCP. In relation to the cases with isolated SMCP with indication for speech prosthesis, the approach was altered to surgery in most cases aged 4 to 6 years; there was similar proportion between maintaining the initial approach and altering to surgery at the age range 7 to 12 years; and the initial approach was maintained for patients older than 18 years; there were no cases of SMCP with cleft lip under this indication. Contrarily, among the cases with indication for surgery, the initial approach was maintained for individuals with both isolated SMCP and SMCP with cleft lip.

Objective: The aim of this study was to evaluate the dentoalveolar effects of rapid maxillary expansion in children with unilateral complete cleft lip and palate in comparison with non-cleft patients. Methods: The experimental group (EG) was composed of 25 patients with unilateral and complete cleft lip and palate (9 males and 15 females) with a mean age of 10.6 years. The control group (CG) comprised of 27 patients without cleft lip and palate (14 males and 13 females) with a mean age of 9.1 years. Dental models of the maxillary dental arch were obtained immediately preexpansion (T1) and 6 months post-expansion (T2) at the time of appliance removal. Digital dental models were obtained using the 3Shape R700 3D laser scanner (3Shape A/S, Copenhagen, Denmark). Transversal widths, arch perimeter, arch length, palatal depth, palatal volume, canine and posterior tooth inclination were digitally measured. Paired t-test was used to perform interphase comparisons and independent t-test to perform intergroup comparisons (p<0.05). Results: In the experimental group, the expansion produced a ignificant increase of all maxillary transverse measurements, palatal volume, arch perimeter and palatal depth while decreased the arch length. RME caused a buccal tip of posterior teeth in patients with UCLP. No differences were observed between experimental and control groups for all the measurements performed except for the intermolar distance (6-6), which showed a greater increase in patients with cleft. Conclusion: Rapid maxillary expansion showed similar dentoalveolar effects in children with UCLP and without oral clefts. / Objective: The aim of this study was to evaluate the dentoalveolar effects of rapid maxillary expansion in children with unilateral complete cleft lip and palate in comparison with non-cleft patients.

Os objetivos do presente estudo foram: 1) mensurar e descrever as medidas de extensão e espessura do véu palatino e da profundidade da nasofaringe em indivíduos com fissura transforame unilateral operada (FTU) que apresentavam disfunção velofaríngea (DVF); 2) calcular e descrever a razão entre a profundidade da nasofaringe e a extensão do véu palatino; 3) comparar as medidas encontradas para os indivíduos deste estudo com as normas descritas por SUBTELNY (1957); 4) comparar as medidas encontradas entre os sexos masculino e feminino; 5) comparar as medidas encontradas para os indivíduos que receberam palatoplastia com procedimento de Furlow (FW) com as medidas daqueles que receberam procedimento de Von Langenbeck (VL); 6) correlacionar as medidas encontradas com as idades dos indivíduos. A casuística foi constituída de 30 indivíduos com FTU e DVF, sendo 15 meninas e 15 meninos, com média de idade de 6 anos e 11 meses. Desses 30, 10 tiveram o palato operado pela técnica de FW e 20 pela de VL, entre as idades de 9 e 18 meses. Para definição da conduta para correção da DVF, todos os indivíduos foram submetidos ao exame de videofluoroscopia. Uma imagem em tomada lateral do MVF em repouso fisiológico foi selecionada e editada em um DVD para análise e mensuração das estruturas velofaríngeas de interesse. Três fonoaudiólogas experientes em videofluoroscopia realizaram as mensurações. Os resultados indicaram média de 27,4 mm para as medidas de extensão do véu palatino, de 9,7 mm para as de espessura do véu palatino, de 22,7 mm para as de profundidade da nasofaringe e de 0,86 para a razão entre a profundidade da nasofaringe e a extensão do véu palatino. Comparando os resultados do presente estudo com os de Subtelny (1957) diferença significante foi encontrada para as medidas da espessura do véu palatino, da profundidade da nasofaringe e da razão entre a profundidade da nasofaringe e a extensão do véu palatino. Os resultados também demonstraram diferença significante entre a média das medidas de extensão do véu palatino nos sexos masculino e feminino. Não houve diferença significante entre a média das medidas das estruturas avaliadas para os indivíduos operados pela técnica de FW nem pelos operados pela VL. Não houve correlação significante entre a variável idade e as medidas obtidas. / The objectives of the present study were: 1) to measure and to describe length and thickness of the velum and depth of nasopharynx for individuals with unilateral operated cleft lip and palate (UCLP) with velopharyngeal dysfunction (VPD); 2) to calculate and describe the depth of nasopharynx to velar length ratio (D/L); 3) to compare measures found for the individuals in this study with the norms described by Subtelny (1957) for normal individuals; 4) to compare the measures between males and females; 5) to compare the measures between individuals who received palatoplasty with the Furlow (FW) procedure to those who received the Von Langenbeck (VL) procedure; 6) correlate measures between different ages. The sample included 30 individuals with UCLP and VPD, 15 girls and 15 boys, with mean age of 6y11m. Ten individuals had palatoplasty with FW procedure and 20 with VL, between the ages of 9 and 18 months. For identifying best procedure for correcting VPD all individuals were submitted to videofluoroscopy assessment. A lateral view of the velopharyngeal mechanism during rest was selected and edited into a DVD, for analysis and measurement of the velopharyngeal structures of interest. Three speech-language pathologists experienced in videofluoroscopic assessment obtained all measures studied. The results revealed a mean velar length of 27.4 mm; mean velar thickness of 9.7 mm; mean depth of nasopharynx of 22.7 mm; D/L of 0.86. Comparing these results to Subtelny\'s (1957) a significant difference was found for measures of velar thickness, depth of nasopharynx velar length and D/L. Significant difference was found between males and females only for velar length. No significant differences were found between different techniques for palatoplasty. There was no significant correlation between age and the measurements obtained.

Os efeitos das cirurgias primárias sobre os arcos dentários vêm sendo objeto de estudo ao longo do tempo. O presente estudo se propõe a avaliar a relação oclusal dos arcos dentários de pacientes com fissura transforame incisivo unilateral submetidos à cirurgia de lábio e palato mole no primeiro tempo e palato duro no segundo tempo por meio de modelos de estudo documentados em pacientes portadores de fissura transforame incisivo unilateral em uma fase mais tardia. Para a avaliação das arcadas utilizou-se o índice oclusal de Goslon (Mars et al 1987) em uma amostra de 42 modelos de gesso de pacientes com idade entre 15 e 19 anos que reparam o palato mole aos 6 meses e o palato duro aos 40 meses. O objetivo dos índices consiste em facilitar o prognóstico e a aplicação de protocolos terapêuticos no tratamento dos pacientes com fissuras de lábio e palato. Em relação aos resultados, a distribuição do Índice oclusal de Goslon foi 42,86% dos pacientes no grupo 1 (G1), 19,05% no grupo 2 (G2), 16,67% no grupo 3 (G3), 7,14% no grupo 4 (G4) e 14,29% no grupo (G5). Para os escores agrupados do índice de Goslon, 61,90 % dos pacientes foram classificados nos grupos 1 e 2 (G1+G2) demonstrando uma relação interarcos satisfatória e 21,43% foram categorizados nos grupos 4 e 5 (G4+G5), considerando uma pobre relação interarcos. / The purpose of this work was to evaluate the outcomes of the application of delayed hard palate closure treatment protocol on the dental arch on a sample of Brazilian patients aging 15 to 19 years old. The sample comprised 42 patients with UCLP, on the permanent dentition, aging 15 to 19 years old, treated with the referred protocol. The mean age of closure was 6 (±3.15) and 40 (±36.07) months for soft and hard palate respectively. Dental casts were obtained and analyzed by a single calibrated (kappa > .71) examiner. Dental arch relationships were accessed on the by applying the Goslon Yardstick, which has been proved to be a useful method for longitudinal assessment of dental arch relationship. The frequencies of each Goslon Yardstick score were described in order to evaluate long-term treatment results on these patients. The distribution of the cases into their assigned Goslon Yardstick scores showed 18 (42.86%) cases on group 1, 8 (19.05%) cases on group 2, 7 (16.67%) cases on group 3, 3 (7.14%) cases on group 4 and 6 (14.29%) cases on group 5. In evaluating the results described, it was possible to conclude that long-term results of delayed hard palate closure treatment protocol for UCLP regarding dental arch relationships were satisfactory on the studied sample: 61.9% of the patients showed excellent or good arch relationship (G1+G2) while 21.43% were classified as having poor or very poor arch relationship (G4+G5).

The International Classification of Function, Disability and Health-Children and Youth Version (ICY-CY), (WHO, 2007) provides an important framework for the holistic consideration of children with communication disorders such as cleft lip and palate. It allows for understanding the effects of a cleft lip and palate on a child’s ability to communicate in structured and natural contexts, going beyond a focus on body structures and functions in order to examine the ways that environmental and personal factors influence the child. Over the years, a number of researchers have applied the ICF-CY framework to children with communication impairments such as speech sound disorders, language impairments, and stuttering. While there is an emerging body of research and literature on this topic, the ICF-CY does not yet appear to be widely applied clinically to children with cleft lip and palate. The aim of the study was to conduct a comprehensive narrative review of the application of the ICF-CY to children with cleft lip and palate, in order to illustrate its use in this population, to identify research needs, and to make recommendations for clinical application to assessment and intervention and integrating the ICF-CY in cleft palate curricula. A systematic search of the literature was conducted by following a specific search strategy and a systematized selection of publications for review to limit researcher bias. Computer searches of electronic data bases, as well as hand searches, were conducted to identify publications and sources that addressed the ICF-CY or ICF in children with cleft lip and palate. Publications and sources that met the inclusion criteria were selected for review. Each source was summarized according to the author(s) and publication year, and a qualitative description of each was made according to structured review procedures and templates. Applications of the specific ICF-CY components to children with cleft lip and palate were mapped, and recommendations for clinical application and future research were described. It is suggested that the ICF-CY framework should be included in cleft palate curricula to provide future speech-language pathologists with a holistic perspective on children with cleft lip and palate and to extend their thinking about the impact of speech impairment associated with cleft lip and palate. Training to adopt the ICF-CY framework will also facilitate collaborative interdisciplinary care of children with cleft lip and palate. Using the ICF-CY framework in the assessment of children in this population will focus intervention on the ultimate goal of improvement of the child's ability to communicate in natural settings. This narrative review will also serve as the theoretical underpinning for a planned survey of the clinical assessment practices of speech-language pathologists treating children with cleft lip and palate.

Development of the secondary palate (SP) is a complex event despite the small area it encompasses. Problems with SP development can lead to a cleft palate, which is one of the most common birth disorders. The matrix metalloproteinases (MMPs) are required for proper SP development, but a functional role for any one of them remains unknown. MMP-25 is a candidate MMP to have a functional role in SP formation as genetic scans of the DNA of human cleft palate patients indicate a common mutation at a region upstream of the Mmp-25 gene. The purpose of this thesis is to investigate gene expression of Mmp-25 in the developing mouse SP, whether it has a functional role in mouse SP development and begin to identify factors potentially upstream of Mmp-25 expression.<p> Mmp-25 mRNA and protein is found at all SP developmental stages in mice with highest expression at embryonic day (E) 13.5 when analyzed by quantitative real-time PCR and western blotting. Immunohistochemistry localizes MMP-25 protein primarily to the plasma membranes of palate shelf epithelial cells with secondary expression in apical mesenchymal cells. Mmp-25 knockdown with siRNA in palatal cultures resulted in a significant decrease in palate shelf fusion and persistence of the medial edge epithelium in vitro. Mmp-25 mRNA and protein levels are significantly decreased in vitro when cultured palate shelves are incubated in growth medium with 5 ìg/ml of a TGFâ3-neutralizing antibody. Mmp-25 gene expression is highest at E12.5 and E13.5, which corresponds to increasing palate shelf growth downward alongside the tongue. Immunohistochemistry localized MMP-25 protein expression predominantly in the epithelium of the palate shelves, but also in areas of the mesenchyme that were immediately adjacent to the epithelium and apical in location. Knockdown of Mmp-25 expression resulted in palate shelf fusion being impaired and significant medial edge epithelium remaining in contacted areas. Bioneutralization of TGFâ3 resulted in a significant decrease in Mmp-25 gene expression. These data suggest a functional role for MMP-25 in mouse SP development by removing extra-cellular matrix barriers to increased palate shelf growth and place its expression downstream of TGF-â3 signaling. This is the first research to present a role for a single MMP in mouse SP development.
