title: Cytological diagnosis of sialadenosis, sialadenitis, and parotid cysts by fine-needle aspiration biopsy.
abstract: This analysis permits the following conclusions: The value of punctate cytology consists in the possibility to verify the clinical diagnosis of a cyst by aspiration of fluid, and to make a preoperative assessment of the necessity of an operation and its type and extent, if proof of a benign or malignant tumor was obtained by microscopic examination. The diagnostic value of punctate cytology can be increased if after aspiration of cyst fluid also solid tissue components from the region of the cyst are included. Patients whose biopsy aspirates did not give evidence for the presence of a tumor should be reexamined 2-4 weeks later. Operative treatment will not be necessary if the follow-up examination reveals that the parotid swelling has subsided. Without this control investigation, recommended by Zajicek [80], morphological aspects always indicate an operation if tumor-negative biopsies cannot be etiologically classified even though clinical data were included in the diagnostic procedure.
