title: [Squamous epithelium in the nasal cytology].
abstract: Nasal mucosa cytology is an additional examination useful to differentiate chronic rhinitis in allergological and laryngological diagnostics, including chronic sinusitis. The aim of the study was to estimate the cytological picture in a group of patients with the highest percentage of squamous epithelia, suggesting the atrophic rhinitis. The analysis was carried out on the basis of cytological results performed in 3055 patients diagnosed because of chronic rhinitis. Among these patients, in 31 individuals the higher percentage (30% - 76%) of squamous cells was found. In six patients, the clear predominance of squamous cells over ciliated and goblet cells (3:1) was reported. Only in three patients the increased percentage in eosinophils was stressed (3%, 5% and 9% respectively). No basic and metaplastic cells were observed in the studied cytograms. The squamous cells occurred probably as a result of normal mucosa damages during the different inflammatory changes, both allergic and non-allergic, the impact of toxic agents, irritants (including nasal drops). The higher percentage of squamous cells in the nasal cytogram could have explained the low effectiveness of local inflammatory treatment in these patients.
