title: [Cytodiagnostic studies of the laryngeal mucosa in chronic laryngitis].
abstract: Cytological diagnostic aids in chronic inflammation of the larynx have been rarely employed so far. A study was conducted to prove whether there is any possibility of larnygeal cytological diagnosis and whether there are any premalignant changes. In view of the results obtained by gynaecological exfoliative cytology, attention was focussed on the metaplastic cells. The frequent incidence of metaplasias was highly significant, whereas dysplasias occurred only in chronic laryngitis besides in tumours. One trend occupying higher cytological diagnostic groups in the Papanicolaou pattern was seen in chronic laryngitis. In our opinion, cytological diagnosis in laryngeal investigation is an aid in the followup control in chronic laryngitis, which is a repeatable procedure without unduly stressing the tissue. Recording of cellular changes in chronic laryngitis can enable a prospective appreciation of morphological changes, which can be useful as diagnostic tool for examining suspicious findings.
