[Conductive deafness without perforation of tympanic membrane with reference to cases of undetermined incudostapedial joint disorder].
In order to elucidate the pathophysiology of an undetermined conductive deafness without perforation of the tympanic membrane, comparative study was made in several factor with conductive deafness which has normal tympanic membrane and may be due to inflammation. Differences and similarities in the manner of ossicular damage were discussed in these conductive deafness. The morbidity rate of con...

متن کاملEustachian tube function in adults with intact tympanic membrane.
UNLABELLED The Eustachian tube has the function of equilibrating the environmental pressure with inner pressure, protecting the middle ear from abrupt pressure changes. AIM To compare the Eustachian tube function in adults with and without history of otitis media and/or respiratory tract inflammation without tympanic membrane perforation. MATERIALS AND METHODS The Eustachian tube function w...
متن کاملDeterminants of Conductive Hearing Loss in Tympanic Membrane Perforation
OBJECTIVES Tympanic membrane perforations are common, but there have been few studies of the factors determining the extent of the resulting conductive hearing loss. The aims of this study were to determine whether the size of tympanic membrane perforation, pneumatization of middle ear & mastoid cavity, and location of perforation were correlated with air-bone gap (ABG) of patients. METHODS F...
