Multi-slice spiral CT and airway reconstruction in 33 patients with obstructive sleep apnea syndrome / 中国组织工程研究

ABSTRACT

This study was designed to investigate the application of multi-slice spiral CT(MSCT)and airway reconstruction in the patients with obstructive sleep apnea syndrome(OSAS).Using GE Lightspeed16 scanner,MSCT and airway three-dimensional reconstruction were performed on 33 patients with OSAS,who were admitted in the Chinese PLA General Hospital between 2004 and 2005.The sagittal diameter,coronal diameter and the section area of upper airway were measured.The results showed that the narrowest place of the airway in OSAS patients was the posterior soft palate region,in which the sagittal diameter,coronal diameter and the section area were 8.96 mm,16.64 mm and 164.62 mm2 respectively,and then was palatine uvula region.With MSCT scanning and post-processing,a precise measurement of airway can be gotten,and stenosis locus and scope are easy to be localized,which will provide reliable evidences for treatment scheme and surgical mode.
