抄録

It is well known that the breathing route affects the upper airway morphology. It has been suggested that patients with obstructive sleep apnea (OSA) have narrower pharyngeal airways than non-OSA patients, therefore breathing with mouth open affect the upper airway morphology of OSA patients significantly compared to non-OSA patients.<br>To assess the relationship between pattern of breathing and upper airway morphology in OSA patients, we perform 3D-CT examination and evaluate the changes of upper airway morphology with mouth open and close with DICOM viewer (Osirix).<br>Eight patients were examined 3D-CT with breathing with mouth open, close. Even in awake, upper airway became narrow with oral breathing.<br>It has been reported that the imaging results while awake do not necessarily reflect conditions during sleep, when tone of the upper airway dilating muscles is decreased. But on the standpoint of relationship between breathing routes and upper airway morphology, 3D-CT while awake can be a useful tool for OSA treatment. DICOM viewer Osirix is free software but very useful tool for evaluate the upper airway morphology.
