Research Abstract |
In the present study, the following fact became clear. 1) A changing pattern of acoustic property of snoring with the change of breathing route has plural types, but the type that sound pressure around 1000Hz increases remarkably by mouth breathing is expected that bilateral palatine tonsil is one of the major site of upper airway obstruction. 2) According to 3D-CT examination, even in awake, upper airway became narrow with oral breathing. 3) Acoustic analysis of snoring sound combined with 3D-CT image analysis could become a useful and less invasive tool for evaluating the upper airway tract configuration.
