Overall Status
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.
Detailed Description
This is a prospective diagnostic test study. Inclusion criteria are all consecutive patients with parotid gland masses referred for treatment at our center, from January 2003 to December 2007.

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.
