[Comparative cytologic studies of human nasal secretions (differential smears of secretions in patients following laryngectomy and patients with rhinitis sicca in comparison with healthy subjects)].

Using a new method, exfoliative cytologic examinations were performed in patients after laryngectomy and in patients with rhinitis sicca in comparison to normal nasal mucosa. In patients after laryngectomy an increased rate of nasal secretion can be seen. In the nasal smear the main fraction of cells are ciliated epithelial cells. Contrariwise, in patients with rhinitis sicca many squamous epithelial cells can be found. The new method enables the preparation of quantitative cytograms.
