Diagnostic Accuracy of Fine Needle Aspiration in Parotid Tumors


Brief description of study

Liberal use of fine needle aspiration biopsy of parotid gland masses is controversial. All information regarding this procedure has been retrospective. Our objective is to evaluate prospectively the diagnostic accuracy of the test, alone and when associated to clinical and/or radiologic data.

The gold standard for the diagnosis of malignancy is the surgical pathology report of the parotidectomy specimen. Cytologist and pathologist will be blind. Diagnostic accuracy is determinded by Bayesian analysis.
