Conductive hearing loss occurs when sound is not conducted efficiently through the outer ear canal to the eardrum and the tiny bones, or 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 medically or surgically corrected.

 Examples of conditions that may cause a conductive hearing loss include:

  • Conditions associated with middle ear pathology such as fluid in the middle ear from colds, allergies (serous otitis media), poor eustachian tube function, ear infection (otitis media), perforated eardrum, benign tumors

  • Impacted earwax (cerumen)

  • Infection in the ear canal (external otitis)

  • Presence of a foreign body

  • Absence or malformation of the outer ear, ear canal or middle ear
