Resumo

Patients with obstructive sleep apnea-hypopnea syndrome (OSAHS) were evaluated using ultrafast magnetic resonance imaging (UMRI) while asleep and awake to analyze tongue changes.The upper airway of 21 OSAHS patients and 20 normal controls were examined during sleep using UMRI.A series of midline sagittal images of the upper airway were obtained to measure dynamic changes in tongue size and the distance from the tongue to the x-axis (an extended line from the anterior nasal spine to posterior nasal spine) and the y-axis (a perpendicular line from the center of the pituitary to the x-axis).The maximum and minimum sagittal ©FUNPEC-RP www.funpecrp.com.br
