An�lise facial em pacientes com Sindrome de Down / Facial analysis in Down?s Syndrome patients

ABSTRACT

Objective: The aim of this study was to analyze the facial features of patients with Down syndrome, such as projection of the nose, projection and length of upper and lower lips, projection of soft pogonion and to compare them with the standardized analysis by Ayala and Gutierrez1. Methods: The sample consisted of 20 patients with Down?s Syndrome, between 8 and 13 years-old of both genders. The analysis was performed by one orthodontist, using lateral cephalograms and photography in natural head position. For statistical analysis, the mean values of linear measurements within a range of 95% were used. Results: The mean (� standard deviation) showed a nasal projection of 10.1 mm (2.4), the upper and lower lip in front of the vertical reference line, subnasal and soft pogonion with a retrusion of 4.95 mm (4.6). The length of the upper lip showed a value of 20.2 mm (2.4) and the length of the lower lip of 42.5 mm (2.9). Conclusion: The facial analysis of patients with Down?s Syndrome, compared with Ayala and Gutierrez1 , showed smaller nasal projection, greater projection of the upper and lower lip, but lengths, and retrusion of the soft pogonion, similar to those of normal individuals.

RESUMO

Objetivo: Realizar uma an�lise das caracter�sticas faciais dos pacientes com S�ndrome de Down quanto � proje��o do nariz, proje��o e comprimento dos l�bios superior e inferior e proje��o do pog�nio mole e compar�-las com a an�lise padronizada por Ayala & Gutierrez1. M�todos A amostra foi composta por 20 pacientes portadores da S�ndrome de Down com idade entre 8 a 13 anos de ambos os g�neros. A an�lise foi efetuada por um �nico ortodontista, utilizando telerradiografias em norma lateral e fotografia em posi��o natural da cabe�a. Para a an�lise estat�stica foram utilizados os valores de m�dia das medidas lineares dentro de um intervalo de confian�a de 95%. Resultados: As m�dias (+ desvio padr�o) revelaram uma proje��o nasal de 10,1 mm (2,4), o l�bio superior e inferior � frente da linha de refer�ncia vertical, subnasal e pog�nio mole com uma retrus�o de 4,95 mm (4,6). O comprimento do l�bio superior apresentou valor de 20,2mm (2,4) e o comprimento do l�bio inferior de 42,5mm (2,9). Conclus�o Conclui-se que pacientes com S�ndrome de Down apresentaram em sua an�lise facial ao se comparar com Ayala & Gutierrez1 menor proje��o nasal, maior proje��o do l�bio superior e inferior, mas comprimentos semelhantes ao de indiv�duos normais, e maior retrus�o do pog�nio mole.
