Final answer:
Conditions such as otosclerosis, inflammation of the labyrinth, and eighth cranial nerve damage may cause conductive hearing loss.
Step-by-step explanation:
Conductive hearing loss is a type of hearing loss that occurs when there is a problem in delivering sound energy to the cochlea. One condition that may cause conductive hearing loss is otosclerosis, which is the abnormal growth of bone in the middle ear that prevents the stapes from vibrating properly.
Another condition that can cause conductive hearing loss is inflammation of the labyrinth, which is the inner part of the ear responsible for balance and hearing. Eighth cranial nerve damage can also result in conductive hearing loss, as the nerve is responsible for transmitting sound signals to the brain.
