Resumo: | Bilateral cleft lip and palate (BCLP) can be considered the most severe of cleft lip and palate (CLP) anomalies, due to its esthetic and functional implications. The rehabilitation process is arduous from the beginning because of the marked forward premaxilla projection, which is an important characteristic in this type of CLP and increases the difficulty of initial surgical procedures. These plastic surgeries can negatively influence the maxillary development. The objective of this study was to evaluate the influence of plastic surgeries (lip and palate repair) on the development of maxillary segments in children with BCLP. This longitudinal observational retrospective study was conducted at the Hospital for Rehabilitation of Craniofacial Anomalies of University of Sao Paulo, Bauru, Brazil. Dental casts were obtained in two times, the first before primary plastic surgeries (T0) and the second after 5 years of age (T1) in the same individual. The scanned dental models were analyzed on a software to obtain angular and linear measurements. The t-test, Mann-Whitney test and Spearman´s correlation test were applied for statistical analysis. There were significant changes in dental casts in T1 that evidenced the influence of primary plastic surgeries on maxillary development. The most affected structure was the premaxilla, and its retropositioning worsened the anterior dental arch collapse. The maxillary and premaxillary development are highly susceptible to primary surgeries performed on the individual with BCLP. |

O processo reabilitador é árduo desde o início, pois a pré-maxilla muito projetada é uma caraterística importante neste tipo de fissura e dificulta o desenvolvimento das primeiras intervenções cirúrgicas, as mesmas que podem influenciar negativamente o desenvolvimento maxilar. O objetivo deste estudo foi avaliar a influência das cirurgias plásticas (queiloplastia e palatoplastia) no desenvolvimento dos segmentos maxilares em crianças com fissura transforme incisivo bilateral. Este estudo retrospectivo longitudinal observacional foi conduzido no Hospital de Reabilitação de Anomalias Craniofaciais da Universidade de São Paulo, Bauru, Brasil. Foram utilizados modelos dentários digitalizados em dois tempos, o primeiro antes das cirurgias primárias (T0) e o segundo a partir dos 5 anos (T1). Os modelos dentários digitalizados foram analisados em um software para obtenção de medidas angulares e lineares. Foram aplicados na análise estatística o teste t, teste de Mann-Whitney e teste de correlação de Spearman. Houve mudanças significativas nos modelos dentários no T1 que evidenciam a influência das cirurgias primárias no desenvolvimento maxilar. A estrutura mais afeitada foi a prémaxila, e o seu retroposicionamento agravou o colapso dentário anterior. O desenvolvimento maxilar e da pré-maxila são altamente suscetíveis às cirurgias primárias realizadas no indivíduo com FTIB.Biblioteca Digitais de Teses e Dissertações da USPDalben, Gisele da SilvaHuayta Aguirre, Ingrid Ivanna 2019-10-22info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisapplication/pdfhttps://www.teses.usp.br/teses/disponiveis/61/61132/tde-28102021-120752/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/openAccesseng2021-12-09T20:59:52Zoai:teses.usp.br:tde-28102021-120752Biblioteca 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:27212021-12-09T20:59:52Biblioteca Digital de Teses e Dissertações da USP - Universidade de São Paulo (USP)false |
