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...

chronic otitis media is a common disease which can lead to serious complications or even death. betterment of eustachian tube function is effective on results of operations. the main goal of this study was to determine the effect of eustachian tube function on outcome of graft in tympanoplasty or tympanomastoidectomy for chronic otitis media. we prospectively studied 126 patients who underwent ...

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...

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...

Objective: To determine Eustachian tube function in tubotympanic type of chronic ear disease and to correlate Eustachian tube function with pathological change in middle ear mucosa. Materials and Methods: A prospective study of the cases of tubotympanic type of chronic suppurative otitis media was undertaken. Patients were subjected to clinical examination followed by audiometry tests and imped...

We used a surgical procedure suggested by Murata et al. and inserted a T-silicon plate from the tympanic cavity into the opening of the eustachian tube in 2 cases of chronic otitis media. The goal of this surgery was to promote the regeneration and the epithelization of residual mucosa of the eustachian tube. In our results, epitheliums of regenerated tympanic mucosa were histologically examine...
