Research Abstract

We have been performed 3D-CT examination and snoring analysis for evaluation of upper airway morphology of OSAS patients. The DICOM data of same patients were examined with INTAGE Volume Editor and Phoenics Special (Ver.2010) for aerodynamic study. With those methods, we could perform dynamic evaluation of the obstruction site of upper airway of OSAS patients.
