Common causes of conductive hearing loss include: 1  Cerumen (earwax) or foreign body in the external auditory canal. 2  Otitis externa, infection or irritation of the outer ear.  Exostoses, abnormal growth of bone within the ear canal.
A conductive hearing loss exists when there is an abnormality in the middle or outer ear but the inner ear (cochlea) functions normally. This causes sound to be attenuated before it reaches the inner ear. This type of loss often can be treated with either medication or surgery.
