Abstract:
OBJECTIVE:To explore a simple and accurate method for localization of upper airway obstruction in patients with obstructive sleep apnea-hypopnea syndrome (OSAHS) and provide instructions for surgical treatment.
METHOD:Fifty OSAHS patients confirmed by PSG underwent acoustic rhinometric and pharyngometric assessment by Eccovision. The parameters were recorded, including nasal minimal cross-sectional area (NMCA), distance of MCA from the nostril (DCAN), minimum cross-sectional area at the nasal valve(MCA), nasal resistance (NR) and nasal volume from 0 to 6 cm from the nostril (NCV), as well as pharyngeal cross-sectional area (CSA) and volume from 4.8 to 15.0 cm. The sensitivity and specificity of acoustic rhinometry and pharyngometry on localization of airway obstruction was determined by a comprehensive imaging and endoscopic study.
RESULT:In 50 cases with severe OSAHS, NMCA, DCAN, MCA, NCV, NR were (0.61 +/- 0.35) cm2, (2.06 +/- 0.12) cm, (0.87 +/- 0.12) cm2, (9.24 +/- 2.31)cm3 and (0.51 +/- 0.32)kPa/(L x min), respectively. Pharyngeal CSA and volume were statistically significantly lower than that in control group (P < 0.01). The value of DCAN was (2.06 +/- 0.12) cm, (9.50 +/- 4.08) cm, (13.10 +/- 2.52) cm in type I II, III patient, respectively. Compared with the control group, the difference was statistically significant.
CONCLUSION:Acoustic rhinometry and pharyngometry is a simple and safe method in localization of airway obstruction in patients with OSAHS.
