Assessment 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 کاملBalloon tuboplasty in patients with Eustachian tube dysfunction: a prospective study in 39 patients (55 ears).
Eustachian tube dysfunction (ETD) is estimated to affect approximately 1% of the UK population. ETD and subsequent inadequate middle ear ventilation have been implicated in the pathogenesis of otological diseases including otitis media with effusion (OME), retraction pockets, tympanic membrane (TM) perforation and cholesteatoma. Patients may present with vague, non-specific symptoms including a...
متن کاملa comparison of teachers and supervisors, with respect to teacher efficacy and reflection

15 صفحه اولFlexibility within the middle ears of vertebrates.
INTRODUCTION AND AIMS Tympanic middle ears have evolved multiple times independently among vertebrates, and share common features. We review flexibility within tympanic middle ears and consider its physiological and clinical implications. COMPARATIVE ANATOMY The chain of conducting elements is flexible: even the 'single ossicle' ears of most non-mammalian tetrapods are functionally 'double os...
