Conductive hearing loss (CHL) results from changes in the outer ear and/or middle ear. With a CHL, sound is not able to travel (be conducted) efficiently down the ear canal, through the eardrum, and along the ossicles (middle ear bones). Some of the more common causes of CHL include the following: fluid in the middle ear, ear infection in either the outer and/or middle ear space, allergies, a hole in the eardrum, ear wax (cerumen) blockage, benign tumor, a foreign object in the ear canal, and the absence or malformation of the outer and/or middle ear. This type of hearing loss is often corrected with medical management or surgery. In some cases, hearing aids may be recommended.
