Abstract

The effectiveness of the Improved Mechanical Therapeutic Nasal Dilator (IMTND) was evaluated rhinomanometrically in 33 patients (mean age: 26 years; range 18-68 years) with anterior nasal obstruction. Using anterior rhinomanometry the patients were observed to have a mean total resistance of 0.376 Pa/cm3/s (range: 0.16-0.87 Pa/cm3/s). There was a significant drop in the inspiratory nasal resistance by 26% after the insertion of the IMTND in the nostrils (p < 0.001). Following decongestion with 1% phenylephrine the resistance decreased by 41%. This difference was statistically significant (p < 0.001). Insertion of the IMTND in the decongested nostrils resulted in even higher and significant decrease in the nasal resistance by 59% (p < 0.001).

摘要

对33例（平均年龄：26岁；范围18 - 68岁）前鼻孔阻塞患者，采用鼻阻力测量法评估改良机械性治疗性鼻扩张器（IMTND）的有效性。通过前鼻阻力测量法观察到，患者的平均总阻力为0.376 Pa/cm³/s（范围：0.16 - 0.87 Pa/cm³/s）。在鼻孔插入IMTND后，吸气鼻阻力显著下降26%（p < 0.001）。用1%去氧肾上腺素减充血后，阻力下降41%。这种差异具有统计学意义（p < 0.001）。在减充血的鼻孔中插入IMTND，鼻阻力甚至更高且显著下降59%（p < 0.001）。
