@entity3540 is constituted of matrix, perimatrix and cystic content. Some authors affirm that, in @entity1 , its clinical behavior is more aggressive of the than in adults. AIMS: Histologic compared @entity3540 of @entity1 and adults. METHODOLOGY: 74 @entity3540 been analyzed, being 35 of pediatrics @entity1 (<18 years). The average number of cellular layers and @entity1373 in the matrix had been evaluated; thickness, delimitante epithelium, @entity82 , @entity32 and @entity738 in the perimatrix. The analysis statistics was carried through with program SPSS 10.0, using the coefficients of Pearson and Spearman, test of chi-square and t test. The number of cellular layers in the matrix was of 8.2+/-4.2. The @entity1373 appears in 17%, @entity82 in 65%, @entity738 in 12% and the delimitante epithelium in 21%. The perimatrix presented a medium one of 80 micrometers (37 the 232), minimum value zero and maximum value 1.926. The histological degree of @entity32 was considered of moderate the accented one in 60%. When applying the coefficient of Spearman enters the @entity32 degree and average of cellular layers of the matrix with the variables of the measure of thickness of the perimatrix we find correlations, significant, with moderate magnitudes of the great ones (rs=0.5 and P<0.0001). CONCLUSION: Adults colesteatomas of and @entity1 had not been identified to morphologic differences between. We find correlation enters the intensity of the @entity32 and of the average of cellular layers of the matrix with the thickness of the perimatrix, what it can predict its @entity146 , more studies are necessary to define the paper of this finding in pathogenesis of @entity3540 .
