Study of acoustic rhinometry and rhinomanometry for normal adult / 临床耳鼻咽喉头颈外科杂志

ABSTRACT

OBJECTIVE@#To obtain the normal values of acoustic rhinometry and rhinomanometry parameters of normal adult and analyze the correlation of two measurement results between rhinomanometry and acoustic rhinometry.@*METHOD@#Eighty-two normal adults were recruited in our research. Acoustic rhinometry was used to acquire unilateral area of first constriction (UA1), unilateral area of second of constriction (UA2), unilateral minimum cross-sectional area (UMCA), unilateral nasal volume 0-5 cm, 2-5 cm (UV5, UV2-5), and rhinomanometer was used to measure the effective unilateral and total nasal resistances in inspiration, expiration at 150 Pa or Broms (radius is 200 Pa) (UR(ins150), UR(ins200), UR(exp150), UR(exp200), TR(ins150), TR(ins200), TR(exp150), TR(exp200)).@*RESULT@#UA1 was (0.63 +/- 0.14) cm2 for male, (0.60 +/- 0.14) cm2 for female; UA2 was (0.72 +/- 0.48) cm2 for male, (0.6 +/- 0.4) cm2 for female; UMCA was (0.50 +/- 0.16) cm2 for male, (0.47 +/- 0.18) cm2 for female; UV5 was (5.68 +/- 1.73) cm3 for male, (5.16 +/- 1.85) cm3 for female; UV2-5 was (4.13 +/- 1.56) cm3 for male, (3.83 +/- 1.66) cm3 for female. No statistical significance was found between men and women (T = 0.093, 0.134, 0.392, 0.408, P > 0.05). UR(ins150) was (0.86 +/- 0.96) Pa/(cm3 x s); UR(ins200) was (0.45 +/- 0.61) Pa/(cm3 x s); UR(exp150) was (0.83 +/- 0.71) Pa/(cm3 x s); UR exp200 was (0.52 +/- 0.88) Pa/(cm3 x s); TR(ins150) was (0.38 +/- 0.34) Pa/(cm3 x s); TR(ins200) was (0.18 +/- 0.24) Pa/ (cm3 x s); TRp(exp150) was (0.38 +/- 0.27) Pa/(cm3 x s); TR(exp200) was (0.19 +/- 0. 24) Pa/(cm3 x s). There was significant correlation between UR(ins150), UR(exp150), TR(ins150), TR(exp150 and UMCA, UV5, UV2 - 5 (P < 0.05, respectively).@*CONCLUSION@#There was correlation between acoustic rhinometry and rhinomanometry. The results of this study can be used as a valuable reference to judge nasal cavity condition of normal adult.
