采用前鼻测压法观察体位变化对NAR的影响,发现正常人在坐位和仰卧位时总NAR无明显差别(p<0. 05)侧卧位时下侧NAR明显升高,上删NAR明显降低(P<0. 05);身体处于不同位置时鼻周期始终存在,侧卧位时下侧NAR波动幅度增大,仰卧位时双侧NAR波动幅度均明显增大,但总NAR却维持在正常范围。在单侧持续性鼻阻塞患者,自发性的鼻周期和体位变化可引起总NAR明显升高,产生双侧鼻阻塞症状。提示体位变化对NAR的影响在解释鼻病患者卧位或夜间睡眠时的严重鼻阻塞症状具有重要意义。
The anterior nasal manometry was used to observe the effect of body position changes on NAR. The results showed that there was no significant difference in the total NAR between sitting position and supine position (p <0.05) (P <0.05). When the body was at different positions, the nasal cycle always existed. The lateral NAR fluctuated more in the lateral position, while the amplitude of bilateral NAR increased significantly in the supine position. However, the total NAR remained within the normal range . In patients with unilateral persistent nasal obstruction, spontaneous nasal cycle and postural changes can cause a significant increase in total NAR, resulting in bilateral nasal obstruction symptoms. Tip changes in the impact of NAR in the interpretation of rhinitis supine or sleep at night when patients with severe nasal obstruction symptoms of great significance.
