ABSTRACT
The objective of this paper was to evaluate the applicability of the method developed by Caldas to measure the vertebral bone age of Brazilians suffering from Down syndrome. A database comprised of 57 case records of individuals with this syndrome, both male and female, with ages ranging between 5 and 18 years, was used for this purpose. These records had lateral cephalometric radiographs and radiographs of hand and wrist, all of which had been obtained on the same date. There were 48 other records of individuals who did not suffer from Down syndrome. The Tanner and Whitehouse (TW3) method was used to perform the hand and wrist radiographs for obtaining bone age. The Caldas method was employed on the lateral cephalometric radiographs in order to obtain the vertebral bone age. From the information acquired on bone age, vertebral bone age and chronological age, it could be concluded that there is a statistically significant difference between the three ages for both the male and the female control group and for the female Down syndrome group. Therefore, this method was employed only on male Down syndrome individuals. Based on the results, a formula was developed to obtain the bone age for Down syndrome individuals (AU).
O objetivo deste trabalho foi avaliar a aplicabilidade do método desenvolvido por Caldas para medir a idade óssea vertebral em brasileiros, quando empregado em indivíduos portadores da síndrome de Down. Foram estudados 57 prontuários de indivíduos com síndrome de Down, de ambos os sexos, com idades variando entre 5 e 18 anos. Esses prontuários continham radiografias cefalométricas laterais e radiografias de mão e punho, obtidas no mesmo dia, e também foram avaliados 48 prontuários de indivíduos não portadores de síndrome de Down. Para as radiografias de mão e punho, o método de Tanner e Whitehouse (TW3) foi usado para que pudéssemos obter a idade óssea. O método de Caldas foi empregado nas radiografias cefalométricas laterais, e assim obtivemos a idade óssea vertebral. A partir das informações sobre a idade óssea, idade óssea vertebral e idade cronológica, foi verificada uma diferença estatisticamente significativa entre as três faixas etárias para ambos os sexos do grupo controle e grupo com síndrome de Down do sexo feminino. Portanto, este método foi aplicável apenas em indivíduos do sexo masculino portadores da síndrome de Down. Com base nos resultados, uma fórmula para obtenção da idade óssea de indivíduos com síndrome de Down foi desenvolvida (AU).

Bone exostosis has long been described in the literature, appearing in most cases as a torus palatinus or mandibularis. These two variations are relatively common and affect approximately 30% of the world's population. Incidence is even higher when human skulls are examined post mortem, indicating that in some cases the exostosis is small and cannot be seen under the soft tissue. Removal of an exostosis is usually associated with the construction of a prothesis, but in rare cases such as the present, the lesion enlarges enough to affect speech and feeding. Few studies have reported the removal of such a large exostosis, and all were conducted in a hospital environment. In this case, complete removal was successfully conducted in an ambulatory clinic under local anesthesia.
