Eustachian tube function in adults with intact tympanic membrane.
UNLABELLED The Eustachian tube has the function of equilibrating the environmental pressure with inner pressure, protecting the middle ear from abrupt pressure changes. AIM To compare the Eustachian tube function in adults with and without history of otitis media and/or respiratory tract inflammation without tympanic membrane perforation. MATERIALS AND METHODS The Eustachian tube function w...
متن کامل[Direct observation of the tympanic cavity by superfine fiberscopy through the eustachian tube].
It was impossible to observe directly the tympanic cavity with the ear drum intact. The superfine fiberscope, developed by the Department of Otolaryngology, Tokyo Medical College, makes it possible to observe the tympanic cavity through the eustachian tube without any surgical intervention such as myringotomy. This fiberscope is flexible and very fine, having an outer diameter of 0.6-0.8mm. Usi...
متن کاملPREVALENCE OF TRAUMATIC TYMPANIC MEMBRANE PERFORATION IN PATIENTS WITH A PATULOUS EUSTACHIAN TUBE
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...
متن کاملAssessment of Eustachian tube function in patients with tympanic membrane retraction and in normal subjects.
INTRODUCTION The diagnosis of Eustachian tube dysfunctions is essential for better understanding of the pathogenesis of chronic otitis media. A series of tests to assess tube function are described in the literature; however, they are methodologically heterogeneous, with differences ranging from application protocols to standardization of tests and their results. OBJECTIVE To evaluate the var...
متن کاملTests of Eustachian tube function: a review.
BACKGROUND Eustachian tube (ET) dysfunction is a common but poorly understood cause of patient symptoms, and an important aetiological factor in the development of middle ear pathology. Despite this, there are no specific tests of ET function in widespread clinical use and no identified 'gold standard' with which to diagnose the disease. OBJECTIVE This review aims to review the literature to ...
