Resumo: | This study aimed to compare the palatal volume in children with unilateral cleft lip and palate before and after two surgical protocols. The sample comprised 120 digitized dental models divided into:Group 1 (G1) children submitted to cheiloplasty at three months (Millard technique) and one-step palatoplasty at 12 months (von Langenbeck technique); Group 2 (G2): children submitted to cheiloplasty (Millard technique) and hard palate closure (Hans Pichler technique) at three months and soft palate closure at 12 months (Sommerlad technique). The dental arches were evaluated at three periods. The volume was measured through stereophotogrammetry system software. Repeated measures ANOVA followed by Tukey test and Friedman test followed by Dunn test was used for intragroup comparisons. Independent t test and Mann-Whitney test evaluated intergroup comparisons. The intragroup analysis revealed that G1 had a statistically significant increase in volume at T2 followed by a reduction at T3 (p=0.003); G2 showed a statistically significant increase of dental arch volume between T1 and T2 (p=0.001). The surgical protocol influenced the palatal volume of children with unilateral cleft lip and palate. This study suggested that two-step palatoplasty was more suitable for dental arch development. |

A amostra foi composta por 120 modelos dentários digitalizados divididos em:Grupo 1 (G1) crianças operadas para reparo labial (técnica de Millard) aos 3 meses e palatoplastia em única etapa (técnica de von Langenbeck) aos 12 meses. Grupo 2 (G2): crianças operadas para reparo labial (técnica de Millard) e do palato duro (técnica de Hans Pichler) aos 3 meses de vida; o reparo do palato mole (técnica de Sommerlad) foi efetuado aos 12 meses. A amostra foi avaliada em três tempos, Tempo 1 (T1) pré cirurgias plásticas primárias; Tempo 2 (T2) 1ª etapa pós cirurgias plásticas primárias; Tempo 3 (T3) 2ª etapa pós cirurgias plásticas primárias. O volume foi analisado por meio do software do sistema de estereofotogrametria. A Análise de Variância (ANOVA) de medidas repetidas seguida pelo Teste de Tukey e o Teste de Friedman seguido pelo Teste de Dunn foram aplicados nas análises intragrupos; enquanto os Testes T independente e MannWhitney, nas comparações intergrupos (nível de significância de 5%). Na análise intragrupo, G1 apresentou diferença estatisticamente significativa com aumento do volume em T2 seguido de uma redução em T3 (p=0.003). Em G2 houve diferença estatisticamente significativa com aumento volumétrico do arco dentário entre T1xT2 (p=0.001).Conclui-se que, o volume dos arcos dentários de crianças com fissura unilateral de lábio e palato foi influenciado pelos protocolos cirúrgicos. Este estudo sugere que reparo do palato em duas etapas é mais adequado para desenvolvimento dos arcos dentários.Biblioteca Digitais de Teses e Dissertações da USPValarelli, Thais Marchini de OliveiraAlcarde, Amanda Ribeiro Homem2021-08-16info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisapplication/pdfhttps://www.teses.usp.br/teses/disponiveis/61/61132/tde-28102021-131525/reponame:Biblioteca Digital de Teses e Dissertações da USPinstname:Universidade de São Paulo (USP)instacron:USPLiberar o conteúdo para acesso público.info:eu-repo/semantics/openAccesseng2024-10-09T13:16:04Zoai:teses.usp.br:tde-28102021-131525Biblioteca Digital de Teses e Dissertaçõeshttp://www.teses.usp.br/PUBhttp://www.teses.usp.br/cgi-bin/mtd2br.plvirginia@if.usp.br|| atendimento@aguia.usp.br||virginia@if.usp.bropendoar:27212024-10-09T13:16:04Biblioteca Digital de Teses e Dissertações da USP - Universidade de São Paulo (USP)false |
