Is the regenerative treatment technology for cochlear hair cells already achieved?

Patient's question:

Because listening to headphones has damaged auditory cells, my hearing has declined for two years. Can medication now regenerate hair cells? Where should I seek medical treatment? How much will it cost? Thank you

Doctor's answer:

Hello, damage to auditory cells can lead to hearing loss.
Guidance: Nerve cells are permanent cells and cannot regenerate, so there is no cure. For your situation, it's important to pay attention to your lifestyle and stay away from noise.
Otitis media in children can cause significant harm to patients. It is recommended that patients seek timely treatment from a specialist under the guidance of a doctor. Daily activities can be appropriate, but be mindful of preventing overheating. We hope the child can recover as soon as possible!
