RESUMEN
INTRODUCTION: Obstructive sleep apnea syndrome has a high prevalence among adults. Cephalometric variables can be a valuable method for evaluating patients with this syndrome. OBJECTIVE: To correlate cephalometric data with the apnea-hypopnea sleep index. METHODS: We performed a retrospective and cross-sectional study that analyzed the cephalometric data of patients followed in the Sleep Disorders Outpatient Clinic of the Discipline of Otorhinolaryngology of a university hospital, from June 2007 to May 2012. RESULTS: Ninety-six patients were included, 45 men, and 51 women, with a mean age of 50.3 years. A total of 11 patients had snoring, 20 had mild apnea, 26 had moderate apnea, and 39 had severe apnea. The distance from the hyoid bone to the mandibular plane was the only variable that showed a statistically significant correlation with the apnea-hypopnea index. CONCLUSION: Cephalometric variables are useful tools for the understanding of obstructive sleep apnea syndrome. The distance from the hyoid bone to the mandibular plane showed a statistically significant correlation with the apnea-hypopnea index.

INTRODUÇÃO: A síndrome da apneia do sono apresenta grande prevalência na população adulta. A cefalometria com análise das variáveis morfológicas pode ser um método valioso na avaliação de pacientes com essa síndrome. OBJETIVO: Correlacionar dados cefalométricos com o índice de apneia-hipopneia do sono, com a finalidade de detectar fatores preditores para a gravidade da síndrome da apneia obstrutiva do sono. MÉTODOS: Trata-se de um estudo retrospectivo, em que foram analisadas cefalometrias de pacientes em acompanhamento no ambulatório de distúrbios do sono da disciplina de Otorrinolaringologia, de um hospital universitário terciário, no período de junho de 2007 a maio de 2012. RESULTADOS: Foram avaliados 96 pacientes, sendo 45 homens e 51 mulheres. Onze pacientes eram portadores de roncopatia, 20 de apneia leve, 26 de apneia moderada e 39 de apneia grave. A única variável cefalométrica que apresentou correlação estatisticamente significante com o índice de apneia e hipoapneia foi a distância linear perpendicular do osso hioide ao plano mandibular. CONCLUSÃO: As variáveis cefalométricas podem ser úteis no entendimento da síndrome da apneia obstrutiva do sono e uma atenção deve ser dada à variável que mede a distância do hioide perpendicularmente ao plano mandibular. .
