Abstract

Abstract: PURPOSE: To evaluate the upper airway condition more precisely by using three-dimensional CT reconstruction (3D-CT) in patients with difficult airway during preoperative assessment. METHODS: A total of 62 obese patients with obstructive sleep apnea-hypopnea syndrome (OSAHS) and normal adults were recruited. ASA grade Ⅱ of obese OSAHS patients was 34. 33± 10. 07 (17-55) years old, with a BMI of (39. 05±
5. 17)kg/m². In the control group, ASA grade Ⅰ to Ⅱ was 28. 34±6. 41 (18-35) years old, and the BMI was (23. 23±
4. 51)kg/m². Mimics 11. 04 was used to analyze the upper airway of OSAHS patients and normal people by reviewing the upper airway 3D-CT data which included the minimum area and the volume of the upper airway. Difference of the upper airway between OSAHS patients and normal ones in 3D-CT reconstruction was analyzed with SPSS 21. 0 software package. RESULTS: OSAHS patients' volume of total airway, retropalatal region and epiglottal region were significantly smaller than the controls (P< 0. 05). There was no significant difference in retroglossal region between OSAHS patients and the controls(P> 0. 05). CONCLUSIONS: 3D-CT reconstruction can display upper airway stenosis and is a good preoperative assessment of difficult airway.
