: Occurs when there is a problem conducting sound waves along the route through the outer ear to the eardrum and tiny bones (ossciles) in the middle ear. This effects the ability to hear faint sounds, and can often be corrected medically, or with surgery.
• Build-up of fluid in the middle ear due to a cold or flu
• Ear Infection
• Perforated Eardrum
• Impacted Earwax
• Presence of a foreign object
• Absence of malformation of the outer ear or ear canal
Sensorineural Hearing Loss: Is the case where there is damage to the inner ear or the nerve pathways from the inner ear to the brain. This is the most common form of permanent hearing loss, as the damage cannot be corrected with surgery.
• Birth Defects
• Head Trauma
• Noise-induced Damage
• Exposure to drugs that are toxic to hearing
Mixed Hearing Loss: This describes a situation when a conductive hearing loss occurs in combination with sensorineural hearing loss. This is caused by damage to the outer, middle, or inner ear or auditory nerve itself, hearing loss is mixed, as the patient displays symptoms and characteristics from both types of hearing loss.
