Hearing loss affects people of all ages and backgrounds, often developing slowly over time and interfering with communication, relationships, and everyday life.
What Causes Hearing Loss?
Hearing loss can be caused by a number of factors, generally grouped into three main types:
Conductive Hearing Loss
This occurs when something is blocking or interfering with the outer or middle ear's ability to transmit sound. It can be caused by:
- Earwax buildup
- Middle ear infections
- Structural abnormalities
- Eardrum damage
Many conductive hearing issues are treatable with office-based procedures or surgery.
Sensorineural Hearing Loss
This type involves damage to the inner ear or hearing nerve and is the most common form of permanent hearing loss. Causes include:
- Age-related degeneration (presbycusis)
- Prolonged noise exposure
- Head trauma or sudden loud blasts
- Genetic or inherited conditions
Sensorineural hearing loss cannot be corrected surgically, but many patients benefit greatly from hearing aids or cochlear implants.
