II. Epidemiology
- Hearing declines by 1 dB per year after age 60
- Incidence Hearing Loss of 25 dB or more- Age 60 to 70 years: 37%
- Age 71 to 80 years: 60%
- Age over 85 years: 80%

III. Causes: Hearing Loss in Older Adults
- 
                          Conductive Hearing Loss
                          - External auditory canal obstruction- Cerumen Impaction
- Large exostoses
- Osteomas
 
- Tympanic Membrane disorder
- Middle ear disorder
 
- External auditory canal obstruction
- Sensorineural Hearing Loss
IV. Risk Factors: Age-Related Hearing Loss
- Alcohol Abuse
- Family History of early Hearing Loss
- Progestin use
- Ototoxic Medications
- Male gender
- Loud noise exposure
- Medical conditions- Diabetes Mellitus
- Renal Failure
- Atherosclerosis
- Head Injury
- Immunosuppression
 
V. Screening
VI. History
- See Hearing Loss
- Unilateral, sudden onset Hearing Loss- Conductive Hearing Loss due to localized cause (see above)
- Idiopathic Sudden Sensorineural Hearing Loss
 
- Grandual onset
- Exposures- Ototoxic Medications
- Infections (e.g. Otitis Media, Otitis Externa, Meningitis)
- Closed Head Injury
- Tympanic Membrane Perforation
- Loud noise exposure (noice induced Hearing Loss)
 
- Associated symptoms- Focal neurologic deficit
- Meniere's Disease

VIII. Management
- See Home Modifications for Hearing Impaired Patients
- See Communication with Hearing Impaired Patients
- 
                          Sensorineural Hearing Loss
                          - Immediately evaluate Sudden Hearing Loss
- Audiology evaluation for Assistive Devices
 
- 
                          Conductive Hearing Loss
                          - Cerumen Impaction is most common (30% of cases)
- 
                              Chronic Serous Otitis Media
                              - Consider nasopharyngeal mass obstructing eustachian tube
