The Eustachian tube has the function of equilibrating the environmental pressure with inner pressure, protecting the middle ear from abrupt pressure changes.
To compare the Eustachian tube function in adults with and without history of otitis media and/or respiratory tract inflammation without tympanic membrane perforation.
The Eustachian tube function was evaluated in forty-two females and males of 18 to 55 years of age with intact tympanic membrane, tympanometric A curves and without historic of otological surgery. The patients (study group with past otological disease) were matched by a control group. The data was analyzed to compare the Eustachian tube function in both groups.
In the study group, 21.4% of the persons presented dysfunction of the tube against 0% in the control group. There was no statistically significant difference considering the affected ear. We observed a higher percentage of men (90.9%) with normal functioning Eustachian tube in relation to women (65%).
Middle ear infections, rhinitis and/or sinusitis influenced the Eustachian tube functioning. Therefore it is important to test its function in such individuals. Other studies are important to establish a standard of normality in each condition of the test and for a better understanding of these people's complaints.
比较有和无中耳疾病/或呼吸道炎症但鼓膜完整、无鼓膜穿孔病史的成年人的咽鼓管功能。
42 名年龄在 18 至 55 岁之间的女性和男性纳入研究，这些患者均有完整的鼓膜、鼓室压图 A 型曲线，且无耳科手术史。将这些患者（研究组）与对照组进行匹配。对两组患者的咽鼓管功能进行比较。
在研究组中，21.4%的人咽鼓管功能异常，而对照组为 0%。考虑到患耳，两组间无统计学差异。我们观察到，男性（90.9%）的咽鼓管功能正常的比例高于女性（65%）。
中耳感染、鼻炎和/或鼻窦炎影响咽鼓管的功能。因此，在这些患者中测试咽鼓管功能非常重要。其他研究对于确定每种情况下的正常标准以及更好地理解这些人的症状非常重要。
