Resumo
Introdução: A disjunção maxilar (DM) é um procedimento ortopédico amplamente utilizado para correção do desenvolvimento oclusal com objetivo de corrigir a deficiência transversal maxilar. Objetivo: O objetivo desse trabalho foi analisar as alterações morfométricas do septo e cavidade nasal pré e pós disjunção maxilar por meio da utilização de Tomografia Computadorizada. Método: Foram avaliados 40 exames de 20 pacientes com idades entre 7 e 13 anos, de ambos os gêneros, portadores de atresia maxilar e com necessidade de disjunção maxilar realizada com o uso do aparelho de Hyrax. Resultados: Na avaliação da amostra, no momento pré disjunção maxilar, a área da fossa nasal é menor que no exame pós disjunção maxilar. A amostra revelou um aumento médio de 12,65% da área da fossa nasal em todos os pacientes. Também foram observadas as alterações à medida que o assoalho da fossa nasal se desloca para baixo e aumenta sua superfície lateralmente. Conclusão: Em análise aos resultados podemos constatar que na totalidade dos pacientes houve aumento na área da cavidade nasal. Não se pode definir para qual lado o septo nasal desvia em função da disjunção maxilar. Ainda em relação a nossa amostra constatamos que 12 pacientes mantiveram como maior lado aquele que previamente já se apresentava assim.
Introduction: The maxillary disjunction (MD) is an orthopedic procedure widely used for correction of occlusal development in order to correct the maxillary transverse deficiency. Objective: The objective of this study was to analyze the morphometric changes of the septum and nasal cavity pre and post maxillary expansion using Computed Tomography. Method: 40 exams from 20 patients, with ages between 7 to 13 years, of both genders, diagnosed with maxillary atresia and need of maxillary disjunction performed using Hyrax apparatus. Results: Evaluating the sample, before the maxillary disjunction procedure the area of the nasal cavity is smaller than the post maxillary disjunction exams. The sample revealed an average increase of 12,65% of the nasal cavity area for all patients. Changes were also observed while the nasal cavity floor moved downwards and increases the surface laterally. Conclusion: Analyzing the results, in all patients was observed that there was an increase in the area of the nasal cavity. It is not possible to define which way the nasal septum deviates according to MD. In relation with our sample was found that 12 patients maintained the larger side as the one that was previously larger while the remainder of the sample had the side of larger area inverted.
