To assess the efficacy of nasal expiratory sound analysis in determining the degree of nasal obstruction.
We have analyzed and recorded the expiratory nasal sounds in 18 healthy controls and in 30 patients with inferior turbinate hypertrophy before and after the administration of nasal corticosteroid treatment. Analysis consisted of the time-expanded waveform, spectral analysis with time-averaged fast Fourier transform and waveform analysis of nasal sound.
Before treatment, an increase in sound intensity at high frequency was observed in the sound analyses of the patients, whereas after treatment, a decrease in sound intensity at high frequency was noted in the sound analyses of the patients. The differences between the patients and the control group were statistically significant. Data obtained with the Odiosoft-Rhino method were correlated with symptom scores and endoscopic examination.
Expiratory nasal sound is a practical and objective tool, which can be reliably used not only for the assessment of the degree of nasal blockage but also for the comparison of different treatment alternatives.
评估鼻呼气声音分析在确定鼻阻塞程度方面的有效性。
我们分析并记录了18名健康对照者以及30名下鼻甲肥大患者在鼻用糖皮质激素治疗前后的鼻呼气声音。分析包括时间扩展波形、采用时间平均快速傅里叶变换的频谱分析以及鼻声的波形分析。
治疗前，在患者的声音分析中观察到高频声音强度增加，而治疗后，在患者的声音分析中注意到高频声音强度降低。患者与对照组之间的差异具有统计学意义。用Odiosoft - Rhino方法获得的数据与症状评分及内镜检查相关。
鼻呼气声音是一种实用且客观的工具，不仅可可靠地用于评估鼻阻塞程度，还可用于比较不同的治疗方案。
