Abstract

Introduction: The Eustachian tube (ET) is essential for fast and direct pressure equalisation between middle ear and ambient pressure. It is not yet known to what extent Eustachian tube function in healthy adults changes in a weekly periodicity due to internal and external factors. This question is particularly interesting with regard to scuba divers among whom there is a need to evaluate intraindividual ET function variability.

Methods: Continuous impedance measurement in a pressure chamber was performed three times at one-week intervals between measurements. Twenty healthy participants (40 ears) were enrolled. Using a monoplace hyperbaric chamber, individual subjects were exposed to a standardised pressure profile consisting of a 20 kPa decompression over 1 min, a 40 kPa compression over 2 min, and a 20 kPa decompression over 1 min. Measurements of Eustachian tube opening pressure (ETOP), opening duration (ETOD), and opening frequency (ETOF) were made. Intraindividual variability was assessed.

Results: Mean ETOD during compression (actively induced pressure equalisation) on the right side was 273.8 (SD 158.8) ms, 259.4 (157.7) ms, and 249.2 (154.1) ms (Chi-square 7.30, P = 0.026) across weeks 1-3. Mean ETOD for both sides was 265.6 (153.3) ms, 256.1 (154.6) ms, and 245.7 (147.8) ms (Chi-square 10.00, P = 0.007) across weeks 1-3. There were no other significant differences in ETOD, ETOP and ETOF across the three weekly measurements.

Conclusions: This longitudinal study suggests low week-to-week intraindividual variability of Eustachian tube function.

咽鼓管功能的个体内变异性：压力舱纵向研究。

简介咽鼓管（ET）对于快速、直接地平衡中耳和环境压力至关重要。目前尚不清楚健康成年人的咽鼓管功能每周会因内部和外部因素发生多大变化。这个问题对于水肺潜水员尤为重要，因为他们需要评估个体内部咽鼓管功能的变化：方法：在压力舱中进行三次连续阻抗测量，每次测量间隔一周。共招募了 20 名健康参与者（40 耳）。使用单点高压氧舱，受试者分别暴露在标准化的压力曲线下，包括 1 分钟内 20 kPa 的减压、2 分钟内 40 kPa 的加压和 1 分钟内 20 kPa 的减压。对咽鼓管开放压力（ETOP）、开放持续时间（ETOD）和开放频率（ETOF）进行了测量。对个体内部的变异性进行了评估：第 1-3 周，右侧压迫（主动诱导压力平衡）期间的平均 ETOD 分别为 273.8（标清 158.8）毫秒、259.4（157.7）毫秒和 249.2（154.1）毫秒（Chi-square 7.30，P = 0.026）。第 1-3 周，两侧的平均 ETOD 分别为 265.6 (153.3) ms、256.1 (154.6) ms 和 245.7 (147.8) ms（卡方 10.00，P = 0.007）。在每周的三次测量中，ETOD、ETOP 和 ETOF 没有其他明显差异：这项纵向研究表明，咽鼓管功能的周内个体间变异性较低。
