Fluid accumulation is the most common cause of conductive hearing loss in the middle ear, especially in children. Major causes are ear infections or conditions that block the eustachian tube, such as allergies or tumors.
Types of Hearing Impairment. The external ear and the middle ear conduct sound: the inner ear receives it. If there is some difficulty in the external or middle ear, a conductive hearing loss occurs. If the trouble lies in the inner ear, a sensorineural (SNHL) or nerve hearing loss is the result. When there is some difficulty in both the middle and inner ear, a combination of conductive and sensorineural impairment exists.
