Conductive Hearing Loss with Intact Tympanic Membrane: Two Cases of Fibrous Change of the Ossicles / 대한이비인후과학회지

ABSTRACT

In general, causes of conductive hearing loss with the intact tympanic membrane and external auditory canal are known as congenital anomaly of the ossicular chain, otosclerosis, and head trauma-induced ossicular discontinuity. But it may also occur due to fibrotic change by potential inflammation of the ossicular chain as a result of otitis media in the infancy or childhood. We report two cases of fibrous change of the ossicles by probable middle ear inflammation with a review of the related literature.
