We sought to evaluate the short-term efficacy of radiofrequency volumetric tissue reduction (RFVTR) in treatment of inferior turbinate hypertrophy (TH) as measured by expiratory nasal sound spectra. In our study, we aimed to investigate the Odiosoft-rhino (OR) as a new diagnostic method to evaluate the nasal airflow of patients before and after RFVTR.
In this study, we have analyzed and recorded the expiratory nasal sound in patients with inferior TH before and after RFVTR. This analysis includes the time expanded waveform, the spectral analysis with time averaged fast Fourier transform (FFT), and the waveform analysis of nasal sound.
We found an increase in sound intensity at high frequency (Hf) in the sound analyses of the patients before RFVTR and a decrease in sound intensity at Hf was found in patients after RFVTR.
This study indicates that RFVTR is an effective procedure to improve nasal airflow in the patients with nasal obstruction with inferior TH. We found significant decreases in the sound intensity level at Hf in the sound spectra after RFVTR. The OR results from the 2000- to 4000-Hz frequency (Hf) interval may be more useful in assessing patients with nasal obstruction than other frequency intervals. OR may be used as a noninvasive diagnostic tool to evaluate the nasal airflow.
我们试图通过呼气鼻声谱评估射频容积性组织减容术（RFVTR）治疗下鼻甲肥大（TH）的短期疗效。在我们的研究中，我们旨在研究Odiosoft-rhino（OR）作为一种新的诊断方法，用于评估RFVTR治疗前后患者的鼻气流情况。
在本研究中，我们分析并记录了RFVTR治疗前后下鼻甲肥大患者的呼气鼻声。该分析包括时间扩展波形、采用时间平均快速傅里叶变换（FFT）的频谱分析以及鼻声的波形分析。
我们发现RFVTR治疗前患者的声音分析中高频（Hf）声音强度增加，而治疗后患者的高频声音强度降低。
本研究表明，RFVTR是改善下鼻甲肥大所致鼻塞患者鼻气流的有效方法。我们发现RFVTR后声谱中高频声音强度水平显著降低。2000至4000赫兹频率（Hf）区间的OR结果在评估鼻塞患者时可能比其他频率区间更有用。OR可作为评估鼻气流情况的无创诊断工具。
