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.
Types of hearing loss. Conductive hearing loss is a form of hearing impairment where the transmission of sound from the environment to the inner ear is impaired, usually from an abnormality of the external auditory canal or middle ear. This form of hearing loss can be temporary or permanent. Untreated chronic ear infections can lead to conductive hearing loss. If fluid is filling the middle ear, hearing loss can be treated by draining the middle ear and inserting a tympanostomy tube. The other form of hearing loss is sensorineural hearing loss, hearing loss due to abnormalities of the inner ear or the auditory division of the 8th cranial nerve.
