单侧前组鼻窦病变对鼻腔通气功能的影响

目的探讨单侧前组鼻窦病变对鼻腔通气功能的影响。方法用Acoustic Rhinometer A1鼻声反射仪和Rhinomanometer NR6-2鼻阻力计测量25例单侧鼻窦病变患者的健侧和患侧鼻腔通气功能,将二者进行对比研究。结果鼻腔0～7 cm,2～5 cm和5～7 cm的鼻腔容积(V0-7,V2-5和V5-7),距离前鼻孔2 cm、4 cm、6 cm处的鼻腔截面积(A2、A4、A6),鼻腔两处最小截面积(MCA1、MCA2)及距前鼻孔的距离(D1、D2),健侧与患侧相比较,两者之间差异无统计学意义(P>0.05)。压差为75 Pa、150 Pa、300 Pa的健侧和患侧的鼻腔气体流量和平均阻力,健侧与患侧相比较,两者之间差异均无统计学意义(P>0.05)。结论前组鼻窦窦口阻塞和鼻窦炎性反应对鼻声反射和鼻阻力的测量结果无明显影响。

Effect of the unilateral anterior group sinusitis on acoustic rhinometry and rhinomanometry

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.
