MétodosTrinta indivíduos do gênero masculino, com idades entre 12 e 15 anos, respiradores bucais ou não, foram selecionados e neles realizados exames de diagnóstico de hipertrofia da adenóide por cefalometria radiológica, a partir da telerradiografia em norma lateral e exames rinoscópicos, a partir da nasofibroscopia (padrão ouro). A cefalometria utilizada foi a computadorizada e para isto se utilizou o programa CefX versão 2000 e a rinoscopia foi realizada com um nasofibroscópio flexível. Foi tomado como ponto de corte 47% e 75% de bloqueio da nasofaringe para a telerradiografia e nasofibroscopia, respectivamente. ResultadosA correlação encontrada entre os dois exames foi considerada moderadamente positiva (0,5) e os testes de validade e confiabilidade registraram uma sensibilidade de 100%, especificidade de 65,5%, valor preditivo positivo de 9,1%, valor preditivo negativo de 100% e exatidão de 66,60%. ConclusãoA telerradiografia lateral foi considerada um meio prático, confortável para o paciente e relativamente eficiente na detecção da hiperplasia da adenóide e na obtenção do diagnóstico de obstrução nasofaringeana.Termos de indexação: Tonsila faríngea. Circunferência craniana. Hipertrofia. Respiração bucal.
Objective: This study evaluated bone age using the Greulich & Pyle method (1959) and pubertal growth according to the study conducted by Martins (1979). Methods: Hand and wrist radiographs of 201 children (103 boys) aged 9 to 12 years living in the state of Amazonas (Brazil) were analyzed. A chi-square test was used for statistical analysis at a level of significance of 5% (p<0.05). Results and Conclusions: Girls were at more advanced stages in all phases of skeletal growth than boys for the ages under study; 50% of the girls had reached pubertal growth peak, whereas only 11.6% of the boys were in the same stage. The beginning and the peak of the pubertal growth spurt occurred earlier among girls (10.1 ± 0.7 and 11.1 ± 0.8 years) than among boys (11.4 ± 0.7 and 12.3 ± 0.4 years). Early maturation was more frequent among girls than among boys (41.8% vs. 5.8%), and late maturation was more prevalent among boys (38.8% vs. 11.2%). Mean bone age in the group of boys was 10.4 ± 1.7 years, and in the group of girls, 11.7 ± 1.8 years. AbstractKeywords: Growth and development. Puberty. Sexual maturity.
