Accuracy of frozen-section diagnosis in salivary gland lesions.

A retrospective study is presented comparing the results of 462 frozen-section analyses of surgically extirpated salivary gland tumors with the permanent-section results. The overall agreement between frozen- and permanent-section analyses was 95.7%. A separate review of the last 47 months of this 32-year study revealed an accuracy rate of 98.8%. Frozen-section diagnosis of salivary gland tumors has been reliable and clinically valuable in our practice.
