Objective Evaluation Of Nasal Ventilation Function In Healthy Adults In Tianjin Area

ObjectiveTo establish reference values of acoustic rhinometry,rhinomanometry and rhinospirometer in healthy adults in Tianjin area, analyze the effect of age,sex and side on the value investigate the correlation of the measure values,offer the diagnosis date for test nasal ventilation function in Tianjin area.Method466 healthy adults in Tianjin area were tested.A1 acoustic rhinometry was used to measure the minimum cross-sectional area(MCA),distance of the minimal cross-sectional area to the nostril (DCAN) and the nasal volume from 0-5cm,2-5cm(NV5, NV2-5);At 150pa,75pa and broms,NR6 Rhinomanometry was used to measure unilateral nasal inspiratory resistance (IR)and expiratory resistance (ER),bilateral nasal inspiratory and expiratory resistance (TIR and TER),and difference of the bilateral nasal resistance can be calculated;NV1 Rhinospirometer was used to mesure unilateral inspiratory capacity (IC) and expiration capacity (EC),and the nasal partitioning ratio (NPR) can be calculated. Practical measure the distance of nostril to ahead of the inferior turbinate and compare with DCAN.Make the correlational analysis on different index of three exam.Result1,Reference values of acoustic rhinometry:MCA was (0.45±0.16) cm2 fro male,(0.44±0.16) cm2 fro female; NV2-5 was (3.52±1.38) cm3 fro male,(3.36±1.22) cm3 fro female, NV5 was (5.10±1.47) cm3 fro male,(4.86±1.12) cm3 fro female; DCAN have two distince, (2.22±0.398,0.53±0.625) cm was for male, (2.10±0.37,0.67±0.15) cm was for female;No significant gender,side and age difference were shown in MCA,V5,V2-5.Significant gender difference was shown in DCAN but no side and age difference.2,Reference values of rhinomanometry: Significant gender but no side and age difference was shown in IR,ER,TIR,TER. 3,Reference values of rhinospirometer:IC wsa (2.06±1.10) L/20s for male, (1.37±0.34) L/20s fro female, EC was (2.15±1.23) L/20s fro male, (1.39±0.58) L/20s fro female. NPRi was 0.11[0.05,0.23],NPRe was 0.11[0.05,0.19].Significant gender but no side and age difference were shown in IC and EC. No gender and age difference were shown in NPRi and NPRe.4,There was significant correlation was found between MCA and IR/ER/IC/EC, IR and IC,ER and EC,Rlr and NPRi/NPRe.ConclusionAcoustic rhinometry,rhinomanometry and rhinospirometer can be useful reference values to evaluate nasal ventilation function, more value will be found if use the three together.1.In acoustic rhinometry,MCA is the most valuable measure,and no gender,age and side difference were shown.Normal population,88.4%(412/466),the narrowest of nasal cavity,or nasal valve area,located in front of the inferior trubinate.2.In rhinomanometry,39%(184/466) of nasal pressure can not achieve 150pa,15%(70/466) of nasal pressure can not achieve 75pa. Significant gender but no side and age difference was shown in IR,ER,TIR,TER.3.In rhinospirometer, Significant gender but no side and age difference was shown in IC and EC,no gender and age were shown in NPR. Rhinospirmeter distinct advantage lies in its ability to judge the openness of the nasal cavity, especially in bilateral symmetry-related diseases (such as septal deviation areas).
