Abstract

Background: A patulous Eustachian tube (PET) may be challenging to diagnose in cases where objective tympanic membrane movement is absent during physical examination.

Objective: The primary aim was to assess the diagnostic usefulness of tubomanometry (TMM) in patients with PET. A secondary aim was to evaluate nasopharyngeal pressure curves as indicators of nasopharyngeal muscle function, given the proposed contribution of muscular dystrophy in PET pathophysiology.

Methods: A retrospective study was conducted at a tertiary referral center on adult patients diagnosed with PET who had undergone TMM between August 2016 and May 2024. Ear-symptomatic patients without Eustachian tube dysfunction or sinonasal disease served as healthy controls. The PET group included 27 ears from 20 patients, and the control group included 91 ears from 49 subjects.

Results: The nasopharyngeal pressure threshold at which middle ear pressure started to increase was markedly lower in the PET than the control group [7.0 mbar (3.0 to 23) vs. 21 mbar (10 to 25), respectively, P=0.014]. A threshold of ≤4.5 mbar showed 90% specificity for PET. No differences were observed in nasopharyngeal pressure curves between the groups, suggesting similar nasopharyngeal muscle dynamics.

Conclusions: TMM showed diagnostic value for PET. No differences in nasopharyngeal muscle dynamics were observed.

咽鼓管扩张术的诊断价值。

背景：在体格检查中没有客观鼓膜运动的情况下，咽鼓管扩张性（PET）可能很难诊断。目的：主要目的是评估TMM在PET患者中的诊断价值。第二个目的是评估鼻咽压力曲线作为鼻咽肌功能的指标，考虑到肌萎缩症在PET病理生理学中的贡献。方法：回顾性研究2016年8月至 2024年5月在某三级转诊中心诊断为PET的成人TMM患者。无耳咽管功能障碍和鼻窦疾病的耳部症状患者作为健康对照。PET组包括20例患者的27只耳，对照组包括49例患者的91只耳。结果：PET组中耳压开始升高时的鼻咽压阈值明显低于对照组[7.0 mbar (3.0 ~ 23) vs. 21 mbar (10 ~ 25)， P=0.014]。阈值≤4.5 mbar表明PET特异性为90%。两组鼻咽压曲线无差异，提示鼻咽肌动力学相似。结论：TMM对PET有诊断价值。鼻咽肌动力学无差异。
