✦ Synopsis


A retrospective review of 57 patients, who had received frozensection diagnoses, was performed both to ascertain the accuracy of diagnosis and to evaluate its usefulness in assessing tumor surgery. Except for 2 cases, each with a parotid gland tumor, the frozen-section diagnoses were consistent with the fi- nal diagnoses using permanent paraffin sections. Fifteen cases with either T1 or T2 squamous cell carcinoma of the oral cavity and 2 cases with malignant salivary gland tumor, showing tumor-free surgical margins by frozen-section examination, were followed. A local recurrence of the carcinoma was observed in 1 case during the follow-up period. Prior to neck dissection, lymph node metastases were examined using frozen sections. Ten cases, which were diagnosed as negative for metastasis,

Background. Both fine-needle aspiration (FNA) and frozen section (FS), although useful in preoperative and intraoperative management, have their advantages and pitfalls when used in the diagnosis of salivary gland lesions. The accuracy of each of these modalities has been assessed separately in many
