To study the influence of endoscopic sinus surgery(ESS) on nasal airway resistance (NAR) and to analyze the relationship between NAR and nasal airflow sensation.
The NAR and nasal airflow sensation were measured with anterior rhinomanometry and visual analogous scale test (VAS) in 42 patients (50 sides) before and after the ESS.
NAR decreased significantly after the operation. The change rates in NAR before and after the decongestion were (55.71 +/- 13.90)% and (24.32 +/- 8.73)%, respectively, and there was a significant difference (P < 0.05). The pathological increase in NAR correlated well with subjective sensation of the patients (P < 0.05).
The improvement of nasal functions by ESS is not due to the alteration of the anatomic structure of the nasal cavity, but to the amelioration of mucosal edema. The rhinomanometry can be used as a useful clinical tool in determining nasal patency.
研究鼻内镜鼻窦手术（ESS）对鼻气道阻力（NAR）的影响，并分析NAR与鼻气流感觉之间的关系。
采用前鼻测压法和视觉模拟评分试验（VAS）对42例患者（50侧）在ESS手术前后测量NAR和鼻气流感觉。
术后NAR显著降低。充血前后NAR的变化率分别为（55.71±13.90）%和（24.32±8.73）%，差异有统计学意义（P<0.05）。NAR的病理性增加与患者的主观感觉密切相关（P<0.05）。
ESS改善鼻功能并非由于鼻腔解剖结构的改变，而是由于黏膜水肿的改善。鼻测压法可作为判断鼻通畅度的有用临床工具。
