探讨鼻腔气流测定在鼻中隔偏曲矫正术中的应用价值。方法：在鼻腔减充血状态下，采用前鼻测压法对２１例患者鼻中隔粘膜下切除术前后的双鼻腔阻力及气流进行测定并予比较。结果：发现双鼻腔气流差异率比鼻气道阻力更能反映鼻通气功能，术前双鼻腔气流差异率绝对值大于５０％的患者预后差，术后患者主观疗效评价与双鼻腔气流差异率相关。结论：双鼻腔气流差异率可作为单侧鼻中隔偏曲矫正术手术患者的选择、预后与疗效评价的一个较好指标。
To explore the value of nasal airflow measurement in nasal septum deviation correction surgery. Methods: In nasal decongestation, nasal resistance and air flow of 21 patients with nasal septum before and after submucosal resection were measured and compared by anterior nasal manometry. Results: It was found that the difference of nasal airway flow between nasal airway resistance and nasal airway resistance was better than that of nasal airway resistance. The preoperative double nasal airflow difference was more than 50%. The subjective efficacy evaluation was correlated with the difference . Conclusion: The difference of nasal airflow in two nasal cavities can be used as a better indicator of choice, prognosis and curative effect in patients with unilateral nasal septum deviation correction surgery.
