Acurácia da análise cefalométrica da faringe para o diagnóstico da síndrome da apnéia obstrutiva do sono (SAOS)

The objective of this study was to verify the accuracy of lateral radiographic cephalometry for the diagnosis of obstructive sleep apnea syndrome (OSAS). The sample was composed of 60 patients, all with clinical suspicion of OSAS. A positive polysomnographic diagnosis requires an apnea-hypopnea index [(A+H)I] per hour of sleep equal to or above five events. A positive cephalometric diagnosis requires superior posterior airway space (PASs)
