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...

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.

Background: Normal Eustachian tube function is one of the important factor required for successful tympanoplasty outcome. A clinically useful test for assessment of Eustachian tube function is still lacking. Aims And Objectives: To evaluate Eustachian tube function by impedance audiometry and compare the outcome of surgery with respect to graft take up in normal and abnormal Eustachian tube fun...

OBJECTIVES To evaluate the effect of OSMF on the eustachian tube function and to correlate it with various grades of the disease. STUDY DESIGN Twenty OSMF patients (40 ears) and 20 healthy controls (40 ears) were evaluated for eustachian tube function by eustachian tube function test, tympanometry and audiometry. RESULTS The audiometric and tympanometric analysis showed no significant diffe...

Introduction: Eustachian tube (ET) dysfunction is a common clinical entity but its treatment is still challenging to Otorhinolaryngologists. This study is done to know the effectiveness of transnasal endoscopic balloon dilatation of eustachian tube for treatment of chronic eustachian tube dysfunction.   Materials and Methods: It is a retrospective observational study conducted between May 2...

BACKGROUND Eustachian tube dysfunction is regarded as a 'black box' term, reflecting a spectrum of dysfunction. The key to its diagnosis and management is in identifying the aetiology and exact pathophysiology of the dysfunction. DESIGN We present our retrospective 5-year results for the technique of transnasal endoscopic balloon dilatation of the cartilaginous part of the Eustachian tube, ba...

The goal of this study was to evaluate the feasibility of endoscopic transtympanic balloon dilation of the cartilaginous eustachian tube. To accomplish this, transtympanic balloon dilation of the cartilaginous eustachian tube was performed on 11 eustachian tubes (6 cadaver heads). The balloon catheter was introduced and passed through the protympanic orifice of the eustachian tube transtympanic...

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...

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...
