[Reliability of cytologic examination in the diagnosis of laryngeal carcinoma (author's transl)].

Cytologic examination has been performed as systematic survey, with drawing by plug in direct laryngoscopy, on 96 patients with intrinsic and extrinsic laryngeal lesions and, as control, on 22 patients with oro- and rhinopharyngeal lesions. The reliability of cytologic diagnosis in relation to the type of the lesion (histologically controlled), to the site of the lesion and to the staining method is evaluated.
