Can mucociliary dysfunction be repaired or restored in chronic upper airway issues, and people with bronchiectasis? If so, how please? Thanks

1ry ciliary dyskinesia. If that what you meant? This is congenital,needs to be diagnosed with electron microscopy of nasal mucosal biopsy, or the saccharine test can give us a clue. At any rate, the microcilia in this condition cannot rid the secretions in the airways,upper/lower, leading to chronic rhinosinusitis /bronchiectasis, prophylactic antibiotics, drainage and chest PT daily are important,keep a close follow up.
