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.
Conductive hearing loss occurs when sound is not conducted efficiently through the outer ear canal to the eardrum and the tiny bones (ossicles) of the middle ear. Conductive hearing loss usually involves a reduction in sound level or the ability to hear faint sounds. This type of hearing loss can often be corrected medically or surgically. Some possible causes of conductive hearing loss: 1  Fluid in the middle ear from colds. 2  Ear infection (otitis media). 3  Allergies (serous otitis media). 4  Poor eustachian tube function. 5  Perforated eardrum. 6  Benign tumors. 7  Impacted earwax (cerumen).
