Abstract: Objective To explore the effect of the unilateral anterior group sinusitis on acoustic rhinometry and rhinomanometry. Methods The nasal ventilation function of 25 patients of lateral sinusitis was detected by acoustic rhinometry and rhinomanometry and then compare the results of normal nasal cavity and affected nasal cavity. Results The nasal volume from 0~7 cm, 2~5 cm, 5~7 cm(V_0-7, V_2-5, V_5-7) was (8.98±3.01)mL, (3.47±1.37)mL, (4.39±1.42)mL of healthy side and (8.59±1.30)mL, (3.09±0.55)mL, (4.07±0.81)mL of affected side respectively. The minimum cross-sectional area(MCA) of the anterior extremity of inferior turbinate and middle turbinate was (0.56±0.35)cm², (1.83±1.13)cm² of normal side and (0.52±0.18)cm², (1.52±0.75)cm² of affected side. The nasal flow rate was F75Pa (193±70)mL/s, F150Pa(271±131)mL/s, F300Pa(225±204)mL/s of healthy side and F75Pa(196±52)mL/s, F150Pa(274±106)mL/s, F300Pa(174±205)mL/s of affected side. The resistance was R75Pa(0.46±0.21)Pa·cm^-3·s^-1, R150Pa(0.55±0.30)Pa·cm^-3·s^-1, R300Pa(0.57±0.57)Pa·cm^-3·s^-1 of healthy side and R75Pa(0.41±0.15)Pa·cm^-3·s^-1, R150Pa(0.50±0.21)Pa·cm^-3·s^-1, R300Pa(0.39±0.47)Pa·cm^-3·s^-1 of affected side. No significant difference was found between healthy side and affected side(P>0.05). Conclusion The acoustic rhinometry and rhinomanometry was not affected significantly by the ostial state of anterior nasal sinusitis and the mild inflammation of the middle nasal meatus.
