Abstract：
Objectives: This study aimed to investigate the effects of seated, supine, and recumbent postures on nasal resistance in individuals with allergic rhinitis (AR) and healthy controls, which has not been investigated in the past. Methods: A visual analog scale (VAS) assessed subjective nasal obstruction, while acoustic rhinometry and video endoscopy provided objective measures. Sixty participants, comprising 30 AR patients and 30 healthy controls, were evaluated across 4 postures without decongestion: seated, supine, left recumbent, and right recumbent. Results: In patients with AR, we noted no significant changes in subjective nasal blockage under various postures (all P > .18). However, significant reductions of minimal cross-sectional area (mCSA) were found (seated vs supine, P = .014; seated vs left recumbent, P = .001; seated vs right recumbent, P < .001) and significant increases in the inferior turbinate hypertrophy were observed on the dependent side of the nose when in recumbent posture (right nose: seated vs right recumbent, P = .013; left nose: seated vs left recumbent, P = .003). On the contrary, healthy controls experienced increased subjective nasal obstruction (VAS scores: seated vs supine, P < .001; seated vs left recumbent, P = .003; seated vs right recumbent, P < .001), reductions in mCSA (seated vs supine, P = .002; seated vs right or left recumbent, both P = .001), and increased inferior turbinate hypertrophy on the dependent side of the nose (right nose: seated vs right recumbent, P = .003; left nose: seated vs left recumbent, P = .006). Conclusions: Healthy controls reported better nasal patency when shifting from supine or recumbent to more upright or less gravity-dependent seated postures, which was further supported by objective examinations. On the contrary, despite patients with AR not subjectively perceiving increased nasal patency while adopting more upright postures, objective evaluations demonstrated an improvement in their nasal airflow in these less gravity-dependent postures.Level of Evidence: 4.
摘要：
目的：本研究旨在探讨坐姿的影响，仰卧,和卧位对过敏性鼻炎（AR）和健康对照者的鼻阻力，过去没有调查过。方法：视觉模拟量表（VAS）评估主观鼻塞，而声学鼻测量和视频内窥镜提供了客观的措施。60名与会者，包括30名AR患者和30名健康对照，在没有缓解充血的情况下对4种姿势进行了评估：坐着，仰卧,左横卧,和右躺。结果：在AR患者中，我们注意到在各种姿势下主观鼻塞没有显著变化(所有P>.18)。然而,发现最小横截面积(mCSA)显著减少(坐位与仰卧，P=.014；坐着与左躺着，P=.001；坐姿与右卧，P<.001）和下鼻甲肥大的显着增加在鼻子的依赖侧时观察到（右鼻：坐姿vs右卧，P=.013；左鼻子：坐着与左躺着，P=.003）。相反,健康对照者主观鼻塞增加(VAS评分：坐姿与仰卧，P<.001；坐姿与左卧，P=.003；坐着与右躺着，P<.001),mCSA减少(坐姿与仰卧，P=.002；坐着与右或左躺，两者P=.001)，并在鼻子的依赖侧增加下鼻甲肥大（右鼻：坐姿vs右卧，P=.003；左鼻子：坐着与左躺着，P=.006）。结论：健康对照者报告说，当从仰卧位或仰卧位转变为更直立或重力依赖性较低的坐姿时，鼻腔通畅性较好。客观考试进一步支持了这一点。相反,尽管AR患者在采取更直立的姿势时主观上没有感觉到鼻腔通畅增加，客观评估显示,在重力依赖性较低的姿势下,他们的鼻腔气流有所改善.证据等级：4。
