[Unilateral patulous eustachian tube with XXXX , inner ear damage, vertigo and sudden deafness--collagen injection].

In elderly @entity1 an unilateral @entity1274 is frequently associated with a relatively more patent eustachian tube on the involved side. A simple method of investigation is observation under the operating microscope during tubal inflation by the @entity1 . In right-handed @entity1 the abnormally patent tube most often lay on the left side. Powerful self inflation in these @entity1 induces acute @entity393 and vertigo. Acute @entity393 is commoner on the left side. The air bone gap is greater at higher frequencies due to mobility of the stapes, loosening of the incudal joints and the tympanic membrane. In contrast the air bone gap is greater at lower frequencies in @entity8719 or malleus head @entity3947 . Minor degrees improve after self inflation is prohibited. In most @entity1 with abnormally patent eustachian tubes further therapy is not necessary after the @entity1 has received precise advice. In only about 20% of the cases is the @entity1 disturbed by a feeling of fullness in the ear, autophony and @entity392 . After stabilisation of weight and blood pressure, a septoplasty with correction of the posterior turbinates may reduce the exspiratory resistance. The most drastic treatment is a collagen injection around the tube. @entity1 with @entity308 should be treated appropriately.
