Objective evaluation of the patency of nasal airway / 临床耳鼻咽喉头颈外科杂志

ABSTRACT

OBJECTIVE@#To obtain the normal values of acoustic rhinometry and rhinomanometry in adult Chinese, analyze the effect of sex and age on the value and investigate the correlation between the two methods.@*METHOD@#One hundred and three normal adults were recruited, Eccovision acoustic rhinometry was used to measure the minimum cross-sectional area (MCA) and the nasal volume from 0-5 cm, 2-5 cm, 0-7 cm (V5, V2-5, V7); ATMO 300 Rhinomanometry was used to measure unilateral and bilateral nasal resistance at 75 Pa and 150 Pa point (R75, R150, R75T, R150T) by anterior active rhinomanometry.@*RESULT@#MCA was (0.66+/-0.18)cm2 for male, (0.57+/-0.16)cm2 for female; V5 was (5.35+/-1.40)cm3 for male, (4.50+/-1.19)cm3 for female; V2-5 was (3.53+/-1.23)cm3 for male; (3.09+/-1.08)cm3 for male; V7 was (9.26+/-2.73)cm3 for male; (8.04+/-2.40)cm3 for female; R75 was (0.66+/-0.34)Pa x cm(-3) x s(-1) for male, (0.77+/-0.33)Pa x cm(-3) x s(-1) for female; R150 was (0.51+/-0.22)Pa x cm(-3) x s(-1) for male, (0.58+/-0.22)Pa x cm(-3) x s(-1) for female, R75T was (0.30+/-0.12)Pa x cm(-3 ) x s(-1) for male, (0.39+/-0.14)Pa x cm(-3) x s(-1) for female; R150T was (0.24+/-0.09)Pa x cm(-3) x s(-1) for male, (0.29+/-0.09)Pa x cm(-3) x s(-1) for female. Significant gender difference was shown in MCA, V5, V2-5, V7, R75, R75T, no significant gender difference was found in R150 and R150T. There was significant correlation between MCA, V5, R75 and age; and there was no significant correlation between R150 and age; significant correlation was found between R75, R150 and MCA, V5, V2-5, V7.@*CONCLUSION@#There is correlation between acoustic rhinometry and rhinomanometry. A statistically significant difference is found between male and female, and age can affect the measurement.
