How do you fix damage cilia in trachea?

Repairing damaged cilia in the trachea primarily involves addressing the underlying causes of the damage, such as quitting smoking, avoiding pollutants, and treating respiratory infections. Supportive therapies, like using humidifiers and saline nasal sprays, can help maintain moisture and promote ciliary function. In some cases, medications or therapies to reduce inflammation may also aid in recovery. However, severe or chronic damage may require more advanced medical interventions.
