[Evaluation of nasal mucociliary activity in laryngectomized patients]

The mucus-ciliar transport (M.C.T.) was studied by the indirect objective method of bleu of metilene in 30 patients undergone (at least since one year) on operation of total laryngectomy. The M.C.T. was absent in 1/3 of the patients and extended in almost all the others this kind of response may be explained as a consequence both of constitutional features and relative inertness of nasal mucous membrane following the absence of ventilation.
