Clinical significance of preoperative imaging in oral squamous cell carcinoma compared with lymph node status: a comparative retrospective study.

Objective: The accuracy and sensitivity of commonly used imaging modalities in evaluating oral cavity cancer was evaluated by comparing the preoperative radiologic findings and the postoperative pathology report.

Study Design: Patients with oral squamous cell carcinoma, who had undergone at least 1 imaging test 2 weeks before surgery were included. Radiologic findings were compared with the dissected neck findings to assess the lymph node status.
