Causes of Conductive Hearing Loss

The second most common type of hearing loss is conductive hearing loss. It is called conductive because there is a problem that interfers with the conduction sound through the ear to the hearing nerves called haircells. Typically, the haircells are healthy and working properly but somthing prevents the sound from reaching the nerves. Problems in the outer and middle ear cause conductive hearing loss.   
Common causes of conductive hearing loss include:
  • Ear wax build up in the ear canal
  • Perforated eardrum (tympanic membrane)
  • Fluid behind the eardrum
  • Middle ear infections
  • Problems with the bones in the middle ear
  • Other middle ear diseases such as otosclerosis
  • A blockage of the Eustachian Tube used to ventilate the middle ear. (The Eustachian Tube can block when flying. Swallowing or yawning can open the tube and allow the middle ear to ventilate.)
Often these types of problems can be resolved.  For example, removing the ear wax opens the canal and allows sound to travel to the eardrum.  Other causes of conductive hearing loss are often treated with medicine and others with surgery. When treament options are not available and conductive hearing loss is permanent, hearing aids are very successful!

Did you know that a middle ear infection is one of the most common diseases in children? Let us know if you or your children have had middle ear infections.
