Evaluation of Drug Effects on Eustachian Tube Dysfunction in Divers
Problems associated with the Eustachian Tube (ET) can result in significant impacts to diving, aviation forces, and hyperbaric medicine. Eustachian tube dysfunction (ETD) is associated with middle-ear barotraumas, which is one of the most prevalent medical complications in the above arenas. The purpose of this trial was to determine the efficacy of various drugs to decrease the incidence of ETD...
متن کاملEustachian tube surfactant is different from alveolar surfactant: determination of phospholipid composition of porcine eustachian tube lavage fluid.
Phosphatidylcholine (PC) is the main phospholipid in lung surfactant and, more specifically, dipalmitoyl PC (PC16:0/16:0) is the major surface-active component. Several studies have tentatively shown that eustachian tube lavage fluid (ETLF) contains surface-active material. The aim of the present study was to determine, using electrospray ionization mass spectrometry, whether the phospholipid m...
متن کاملSurfactant proteins A and D in Eustachian tube epithelium.
Surfactant protein (SP) A and SP-D are collectins that have roles in host defense. The Eustachian tube (ET) maintains the patency between the upper airways and the middle ear. Dysfunction of local mucosal immunity in ET may predispose infants to recurrent otitis media. We recently described preliminary evidence of the expression of SP-A and SP-D in the ET. Our present aim was to establish the s...
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 ...
متن کاملRunning Title: Eustachian tube mechanics The Effect of Surface Tension and Surfactant Administration on Eustachian Tube Mechanics
The development of Otitis media has been related to abnormal Eustachian tube (ET) mechanics. The ET is a collapsible tube that is periodically opened to regulate middle ear (ME) pressure and clear ME fluid into the nasopharynx. The ability to perform these physiological functions depends on several mechanical properties including the ET’s opening pressure (Popen), compliance (ETC), and hysteres...
