Middle ear barotrauma is a tissue injury to the ear secondary to inadequate pressure equalisation between the middle ear and the external environment. Paragliding, though an exciting sport, has its own risks and hazards. Para-pilots experience a variety of ear-related symptoms due to pressure discrepancies between the middle ear and ambient air. Middle ear barotrauma amongst para-pilots is a common yet neglected problem. The aim of this study was to find the prevalence of middle ear barotrauma among licensed para-pilots of a metropolitan city.
A descriptive cross-sectional study was conducted amongst para-pilots practising in different paragliding companies in a metropolitan city. The study was conducted from 10th October, 2021 to 22nd October, 2021 after getting ethical approval from the Institutional Review Committee (Reference number: 0410202109/2021). A sample size of 76 participants was taken using convenience sampling technique. Data was collected from participants after performing an otoscope examination. The data were entered into Microsoft Excel version 2016 and analysed using the Statistical Package for the Social Science Version 22.0. Point estimate at a 95% Confidence Interval was calculated along with frequency and proportion for binary data and mean and standard deviation for continuous data.
Out of 76 participants, the prevalence of middle ear barotrauma was 10 (13.2%) (5.58-20.81 at 95% Confidence Interval).
The prevalence of middle ear barotrauma was similar to other studies done in similar settings.

中耳气压伤是由于中耳与外环境之间的压力平衡不足而导致的耳部组织损伤。滑翔伞运动虽然令人兴奋，但也有其自身的风险和危害。由于中耳与环境空气之间的压力差异，滑翔伞飞行员会经历各种与耳朵相关的症状。滑翔伞飞行员中耳气压伤是一个常见但被忽视的问题。本研究旨在调查大都市地区有证滑翔伞飞行员中耳气压伤的患病率。
在大都市的不同滑翔伞公司中，对滑翔伞飞行员进行了描述性横断面研究。该研究于 2021 年 10 月 10 日至 22 日进行，在获得机构审查委员会的伦理批准（参考编号：0410202109/2021）后进行。使用便利抽样技术抽取了 76 名参与者的样本量。在对参与者进行耳镜检查后，从参与者那里收集数据。将数据输入 Microsoft Excel 版本 2016 并使用统计软件包 22.0 进行分析。计算了 95%置信区间的点估计值以及二进制数据的频率和比例以及连续数据的均值和标准差。
在 76 名参与者中，中耳气压伤的患病率为 10 例（13.2%）（95%置信区间为 5.58-20.81）。
中耳气压伤的患病率与类似环境下的其他研究相似。
