Sonographically guided core biopsy of the salivary gland masses: safety and efficacy.

Over an 8-year period, we performed ultrasonography (US)-guided core biopsy of the salivary gland in 37 patients using an 1l-mm-throw 18-gauge automated biopsy system. The biopsy results were retrospectively compared with the findings of surgical pathology (n=18) or more than 6 months of clinical follow-up (n=19). The sensitivity, specificity, and accuracy of US-guided core biopsy for the diagnosis of malignancy were 75.0%, 96.6%, and 91.9%, respectively. No immediate or delayed complications occurred.
