Patulous Eustachian tube (PET), a practical overview

Symptoms of patulous Eustachian tube(ET),particularly autophony,can overlap with other conditions,and can arise from a variety of causes.We review the pathophysiology of“speech hyper-resonance syndromes”,and possible mechanisms,including resonances in the tympanic membrane,Eustachian tube and nasopharynx.Treatment can be directed at the eardrum or the ET depending on site of pathology.We review typical presentations,examination findings,and useful clinical tests to distinguish PET from other disorders,and our philosophy of management.

七项咽鼓管功能障碍症状评分量表在评估咽鼓管异常开放症中的应用分析

目的 探讨七项咽鼓管功能障碍症状评分量表(the seven-item Eustachian tube dysfunction questionnaire,ETDQ-7)对量化评估咽鼓管异常开放症(patulous Eustachian tube,PET)的可靠性及临床价值。方法 选取2016年4月~2019年10月于佛山市第二人民医院耳鼻咽喉科门诊就诊的PET成年患者34例(51耳)作为观察组,对照组20名(40耳),采用ETDQ-7分别对观察组和对照组进行问卷调查,计算得分情况,并通过Cronbach’s α信度系数评判量表内部一致性、接收者操作特征曲线(ROC)明确量表诊断价值。结果 ETDQ-7作为PET调查量表,α信度系数为0.879,ROC曲线下面积(AUC)0.966,量表的灵敏度为96.1%,特异度85%。结论 ETDQ-7用于评估PET其信度可靠,价值高,能有效评判PET成年患者主观症状的严重程度。
