目的：探讨鼻声反射和鼻阻力（NR）检查结果在鼻内镜下低温等离子射频消融术疗效评价中的临床意义。方法：选取2011年5月-2014年5月本院收治的中重度慢性鼻炎患者90例作为研究组，药物治疗效果欠佳，择期行鼻内镜下低温等离子射频消融术，采用视觉模拟评分法（VAS）评价手术前后疼痛程度。另择同期90例健康体检者作为对照组，两组分别于鼻黏膜收缩前和收缩后进行鼻声反射及NR检查，结合VAS疼痛评分评价临床疗效。结果：手术前，研究组患者鼻黏膜收缩前后双侧鼻腔各项指标比较差异均无统计学意义（P>0.05）；与手术前比较，研究组术后鼻腔最小横截面积（NMCA）和鼻腔容积（NCV）增大，NR减小，比较差异均有统计学意义（P<0.05），鼻腔最小横截面积至前鼻孔的距离（DCAN）和鼻腔平均横截面积（MNCA）比较，差异均无统计学意义（P>0.05）；术后VAS评分明显低于术前，比较差异有统计学意义（P<0.05）；两组术后各项指标比较，差异均无统计学意义（P>0.05）。结论：鼻内镜下低温等离子射频消融术治疗中重度慢性鼻炎效果确切，可有效改善鼻通气功能，鼻声反射和鼻阻力检查结果可准确反映临床疗效。%Objective:To investigate the clinical significance of nasal acoustic reflex and nasal resistance (NR) test results in the evaluation of low temperature radiofrequency ablation under endoscopic sinus surgery. Method:From May 2011 to May 2014,90 cases of moderate and severe chronic rhinitis in our hospital were selected as the research group,which drug therapy effect were not good and selected nasal endoscopic low temperature plasma radiofrequency ablation.The visual analogue scale (VAS) was used to evaluate the degree of pain before and after surgery.90 cases of healthy people during the same period were selected as the control group, the nasal acoustic reflex and NR test before and after nasal mucosa contraction combined with VAS pain score were compared.Result:Before surgery,there were no significant differences in the bilateral nasal index of research group before and after nasal mucosa contraction(P>0.05).Compared with before surgery,the researh group minimum cross-sectional area of the nasal cavity (NMCA) and nasal volume (NCV) increased,NR decreased, the differences were statistically significant(P<0.05),the minimum cross-sectional area of the nasal cavity to the distance from the front (DCAN) and average cross-sectional area of nasal cavity (MNCA) were not statistically significant(P>0.05),postoperative VAS score was significantly lower than preoperative,the difference was statistically significant(P<0.05).There was no significant difference between the control group and the study group after surgery(P>0.05).Conclusion:Low temperature radiofrequency ablation under endoscopic sinus surgery for the treatment of moderate and severe chronic rhinitis has exact effect.It can effectively improve the nasal airway function,nasal acoustic reflex and NR test results can accurately reflect the clinical efficacy.
