1.Injury or Pressure Changes
A serious head injury can dislocate your middle-ear bones or damage nerves and cause permanent hearing loss. Sudden changes in pressure from flying or scuba diving could also harm your eardrum or middle or inner ear. Eardrums usually heal in a few weeks. But if your inner ear is badly injured, you may need surgery. Never stick cotton swabs or other objects into your ears. This can break your eardrum and cause permanent damage.
2.Medicines
Hearing loss can be a side effect of some medicines, including certain antibiotics, cancer medications, and erectile dysfunction drugs. Your doctor will probably keep an eye on your hearing while you take them. But some hearing loss may be permanent.
