Nasal mucociliary function after laryngectomy

: We have made a comparative study of nasal mucociliary transport in 46 normal persons and in 31 laryngectomees, with the charcoal powder technique. Nasal mucociliary transport time is significatively increased in laryngectomized patients (p less than 0.000001) and there aren't statistical correlation between the time after laryngectomy and the nasal mucociliary transport time.
