Prevention

Preventive measures can be very useful to decrease the frequency of otitis externa. On the other hand, otitis media is difficult to prevent. Avoid the risk factors outlined under Causes, if possible.

• Otitis externa prevention-preventing moisture in the ear

• Careful drying of the ear after swimming or bathing
• Shaking out excess water
• Holding a hair drier on low heat setting at least 12 inches from the ear
• Wearing earplugs while swimming

• Homemade solution of 1/2 rubbing alcohol, 1/4 white vinegar, and 1/4 distilled water may be used for tougher cases.
  • Place 3-4 drops in each ear after swimming or bathing.
  • Do not use drops if there is a hole (perforation) in the eardrum or if there is a ventilation tube in the ear.
  • Immediately discontinue drops if any pain occurs.

• Otitis externa prevention-preventing scrapes to ear canal

• Careful cleaning of ears to avoid scraping the ear canal.
• Do not use objects (for example, paper clips, bobby pins, or fingernails) that may tear the skin. Most people have ears that are self-cleansing, and cleaning with a cotton-tipped swab is unnecessary and potentially harmful.

• Otitis media prevention

• Avoid risk factors (for example, secondhand smoke, daycare), if possible.

• Treat severe allergies.
• Avoid contact with others who have a cold or respiratory infection.

• In severe cases, a prolonged course of an antibiotic can be used as a preventive measure.
