background: with respect to physical relations in force and pressure, we hypothesized that the prevalence of traumatic tympanic membrane perforation in patients with a patulous eustachian tube is greater than normal, because in eustachian tube patency, the internal air pressure of the middle ear will not increase after compression, subsequent to trauma. therefore the force upon the tympanic mem...

PURPOSE OF REVIEW The purpose of this review is to summarize the recent knowledge on eustachian tube dysfunction and the patulous eustachian tube. RECENT FINDINGS A clinically useful test for eustachian tube function is still lacking. Narrowing of the isthmus alone was demonstrated to be an insufficient cause of otitis media. Inflammatory mediators identified within the eustachian tube and mi...

The diagnosis and treatment of patulous eustachian tube were discussed with review of the literature. In addition, some new findings from the author's group related to this difficult disorder were presented. We have used 3-dimensional reconstruction of the computed tomography (3D-CT) of the eustachian tube lumen to detect very severe cases of the patulous eustachian tube. The new treatment of t...

OBJECTIVE To determine eustachian tube function in patients with asthma and with or without eosinophilic otitis media (EOM), a new middle ear disease entity with a highly viscous middle ear effusion containing many eosinophils and usually associated with bronchial asthma. One of the most important causes of otitis media (OM) is eustachian tube dysfunction. DESIGN Retrospective case review. ...

Patulous Eustachian tube (PET) is a common condition that produces symptoms of aural fullness and autophony. We describe a Parkinson's disease (PD) patient that experienced a reversible bilateral patulous (hyperpatent) Eustachian tube syndrome induced by treatment with amantadine hydrochloride. The clinical features, relevant anatomy and physiology, and associated risk factors for PET are revie...

The patulous, or nonclosing, eustachian tube is believed to affect as many as 7 percent of all adults, causing physical and psychological difficulties. This paper provides a brief review of the literature regarding the patulous eustachian tube (PET), its symptoms, precipitating conditions, incidence, diagnosis, and current medical management. Several case studies are also presented to illustrat...

BACKGROUND Application of one or several paper patches on the tympanic membrane can improve autophony and other symptoms in some patients with a patulous eustachian tube. METHOD The charts of 21 patients treated for patulous eustachian tube syndrome between 2006 and 2011 were studied for subjective improvement of symptoms following the application of paper patches. RESULTS Paper patching of...

Objective: Autologous lipoinjection for patulous Eustachian tube dysfunction was investigated. We studied the technique of fat harvesting, fat tissue changes due to processing, clinical application and preliminary outcomes. Design: Prospective pilot cohort study. Methods: Transnasal endoscopic injection of autologous lipoinjection into the posterior cushin was performed in 8 patients as a new t...

Title: Meniere’s disease with patulous eustachian tubes Background: Meniere’s disease (MD) is considered to be a multifactorial disease. Although there are some previous reports on the relationship between MD and stenotic eustachian tube (ET), there are a few reports evaluating MD and patulous ET. The study aimed to investigate whether MD would have patulous ET or not. Methods and Findings: Son...
