Conductive Hearing Loss

Types of Hearing Loss: Conductive Hearing Loss | Sensorineural Hearing Loss | Mixed Hearing Loss

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:

  • Fluid in the middle ear from colds
  • Ear infection (otitis media)
  • Allergies (serous otitis media)
  • Poor eustachian tube function
  • Perforated eardrum
  • Benign tumors
  • Impacted earwax (cerumen)
  • Infection in the ear canal (external otitis)
  • Swimmer's Ear (otitis ecxterna)
  • Presence of a foreign body
  • Absence or malformation of the outer ear, ear canal, or middle ear
