          Abstract

          RESUMO Objetivo Comparar a geometria da cavidade nasal de crianças e adolescentes com fissura labiopalatina e deficiência maxilar por meio de dois métodos: a tomografia computadorizada de feixe cônico, considerada padrão-ouro, e a rinometria acústica. Método Foram avaliados, de maneira transversal, os exames de tomografia computadorizada de feixe cônico e de rinometria acústica, previamente obtidos para fins de planejamento ortodôntico, de 17 crianças e adolescentes com fissura labiopalatina e atresia maxilar. Por meio do programa Dolphin Imaging 11.8, a cavidade nasal das imagens tomográficas foi reconstruída por dois avaliadores e foram obtidos os volumes internos nasais. Por meio da rinometria, os volumes nasais foram aferidos para as regiões V1 e V2. Os valores de cada exame foram, então, comparados, a um nível de significância de 5%. Resultados A análise estatística mostrou alta reprodutibilidade intra e interavaliadores na análise da tomografia computadorizada de feixe cônico. Os volumes internos nasais médios (± desvio-padrão), utilizando a rinometria acústica e a tomografia computadorizada de feixe cônico corresponderam a 6,6 ± 1,9 cm3 e 8,1 ± 1,5 cm3, respectivamente. A diferença entre os exames foi de 17,7%, considerada estatisticamente significante (p = 0,006). Conclusão Os volumes nasais aferidos pelos dois métodos são diferentes, ou seja, apresentam discrepâncias nas medidas. A técnica considerada padrão-ouro identificou volumes maiores na cavidade nasal. A determinação de qual exame reflete a realidade clínica constitui passo futuro importante.

          ABSTRACT Purpose To compare the nasal cavity geometry of children and teenagers with cleft lip and palate and maxillary atresia by two methods: cone-beam computed tomography, considered the gold standard, and acoustic rhinometry. Methods Data on cone-beam computed tomography and acoustic rhinometry examinations of 17 children and teenagers with cleft lip and palate and maxillary atresia, previously obtained for orthodontic planning purposes, were evaluated prospectively. Using Dolphin Imaging 11.8 software, the nasal cavity was reconstructed by two evaluators, and the internal nasal volumes were obtained. Using rhinometry, the volumes of regions V1 and V2 were measured. The values of each examination were then compared at a significance level of 5%. Results Statistical analysis showed high intra- and inter-rater reproducibility in the cone-beam computed tomography analysis. The mean internal nasal volumes (± standard deviation) obtained using acoustic rhinometry and cone-beam computed tomography corresponded to 6.6 ± 1.9 cm3 and 8.1 ± 1.5 cm3, respectively. The difference between the examinations was 17.7%, which was considered statistically significant (p = 0.006). Conclusion The nasal volumes measured via the two methods were different; that is, they presented discrepancies in the measurements. The gold standard technique identified larger volumes than acoustic rhinometry in the nasal cavity. Therefore, determining which test reflects clinical reality is an essential future step.

          Gene/environment causes of cleft lip and/or palate.

          J Murray (2002)
          Craniofacial anomalies, and in particular cleft lip and palate, are major human birth defects with a worldwide frequency of 1 in 700 and substantial clinical impact. A wide range of studies in developmental biology has contributed to a better knowledge of how both genes and environmental exposures impact head organogenesis. Specific causes have now been identified for some forms of cleft lip and palate, and we are at the beginning of a time in which the common nonsyndromic forms may also have specific etiologies identified. Mouse models have an especially important role in disclosing cleft etiologies and providing models for environmental cotriggers or interventions. An overview of the gene-environment contributions to nonsyndromic forms of clefting and their implications for developmental biology and clinical counseling is presented.

            Rehabilitative treatment of cleft lip and palate: experience of the Hospital for Rehabilitation of Craniofacial Anomalies/USP (HRAC/USP) - Part 1: overall aspects

            Cleft lip and palate is the most common among craniofacial malformations and causes several esthetic and functional implications that require rehabilitation. This paper aims to generally describe the several aspects related to this complex pathology and the treatment protocol used by the Hospital for Rehabilitation of Craniofacial Anomalies, University of São Paulo (HRAC-USP) along 40 years of experience in the treatment of individuals with cleft lip and palate.
