Conductive hearing loss

hearing loss caused by interference with sound transmission in the external auditory canal or middle ear. The aetiology of conductive hearing loss is very diverse, and may be congenital (e.g. malformation or atresia of the external auditory canal, malformation of the ossicles), inflammatory (e.g. otitis media, cholesteatoma), postinflammatory (e.g. tympanosclerosis), traumatic (disruption of ossicular chain, posttraumatic stenosis of external auditory canal), otosclerosis, osteodysplastic (e.g. fibrous dysplasia head and neck), or tumoral (e.g. external auditory canal carcinoma, nasopharynx cancer with secondary otitis serosa).
