Some of the causes of conductive hearing loss include: PROBLEMS WITH THE EXTERNAL EAR WHAT CAN CAUSE CONDUCTIVE HEARING LOSS?Ĭonductive hearing loss may result from diseases that affect the external ear or middle ear structures. An otolaryngologist, also called an Ear Nose and Throat or ENT doctor, can determine the specific diagnosis and treatments for either type of hearing loss and perform surgical treatments, if necessary. The distinction between these two types of hearing loss is important because many cases of conductive hearing loss can be improved with medical or surgical intervention. ![]() A formal audiogram, or hearing test, is the best way to determine the type and degree of hearing loss. The preliminary classification of hearing loss as conductive or sensorineural can be determined by a physician using a tuning fork in the office. Mixed hearing loss refers to a combination of these two types. Hearing loss can be divided into two types: Conductive Hearing Loss, which is essentially a mechanical problem with the conduction of sound vibrations, and Sensorineural Hearing Loss, a problem with the generation and/or transmission of nerve impulses from the inner ear to the brain. ![]() The sound vibrations in the ossicles are then transmitted to the nerves and fluids in the cochlea (inner ear), which generates a nerve impulse that passes along the auditory nerve to the brain. Sound waves enter the ear canal and cause a vibration of the tympanic membrane (ear drum) which is then passed through three tiny bones behind the ear drum in the middle ear space: the malleus (hammer), incus (anvil) and stapes (stirrup). The ear can be divided into three parts: 1) the external ear includes the pinna (outer, visible ear) and the ear canal, 2) the middle ear includes the tympanic membrane (ear drum) and the ossicles (middle ear bones), 3) the inner ear, which includes the cochlea (organ of hearing) and vestibule (organ of balance).
