Otitis media is mainly avoided by removing possible causes and risk factors and improving the body’s immunity to avoid recurrent attacks. 1. Strengthen physical exercise, enhance physical fitness, and pay attention to cleanliness and hygiene. 2. Actively prevent and treat upper respiratory tract infections and respiratory infectious diseases. 3. Learn the hygiene knowledge of blowing nose correctly, and don’t exert too much force when blowing nose to prevent infection caused by snot entering the tympanic chamber. 4. Keep the external ear canal dry. After bathing or swimming, you can turn one ear down to empty the water inside, or use a dry cloth to wipe the auricle and other easy-to-clean places. 5. Disable the use of hard objects to pull out the ear to prevent damage to the eardrum. 6. Quit smoking and avoid inhaling second-hand smoke. 7. When breastfeeding babies, take a half-sitting position to prevent choking. If otitis media has been cured, you need to go to the hospital regularly for review, follow the doctor’s instructions to standardize the use of medication and treatment, to avoid repeated attacks stimulated by adverse factors.
