Abstract:

Based on the literature reviews summarize the diagnostic value of fine needle and core needle biopsy in salivary gland masses, revealing the advantages and disadvantages of these two methods.Salivary gland tumors are diagnostic challenge in a clinical practice and an accurate diagnosis is essential for its adequate management.Fine needle aspiration cytology and core needle aspiration cytology are a useful techniques for evaluating masses suspected of being of salivary gland origin.The reported diagnostic accuracy of FNAC can be as high as 98% when adequate material is obtained, but the rate of insufficient or non-diagnostic rate is up to 29%.Core needle biopsy aids in differentiating malignant from benign masses with reported sensitivities of 75~89%, specificities of 96.6~100%, and accuracies of 91.9~100%.Conclusions:Studies have shown that fine needle and core needle aspiration cytology have high sensitivity and specificity for salivary gland lesions. In the absence of ultrasound-guidance, or on-site cytopathologist, the accuracy of these methods often falls off dramatically.
